idea使用maven從0整合ssm+shiro

1. 搭建環境

idea2017

maven3

jdk1.8

2. 整合ssm

首先新建一個maven工程，空的也無所謂，構建目錄結構，如圖1.

目錄搭建好了，可以開始整合ssm了。首先把jar給導入，maven就是幫我們干這個事情的。除了jar包的依賴管理，還有編譯的一些配置可以設置。我把我的maven的pom.xml給貼上來吧。如果不知道怎麼弄maven，你可以先去看一下idea 配置maven的blog。如果是eclipse的話，請你走吧，我試過幫我同學弄，出現很多問題，比如xsd重複這些，如果你是新手eclipse和idea都不熟悉，你還是下載idea吧。然後邊百度邊使用idea。

jar包導進來了。你可能會問這麼多jar包啊，我怎麼知道。對不起，我也是百度過來的。有些jar包我知道，有些我不知道。抱歉。繼續。web工程都先看WEB-INF下面的web.xml的配置，無論哪個web工程。那麼我先把我整理過的web.xml貼上來。

   <?xml version="1.0" encoding="UTF-8"?>  <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"           xmlns="http://java.sun.com/xml/ns/javaee"           xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"           version="3.0">    <display-name>ssm</display-name>    <context-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:./spring-cfg.xml</param-value>    </context-param>      <!-- 編碼過濾器 -->    <filter>      <filter-name>encodingFilter</filter-name>      <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>      <async-supported>true</async-supported>      <init-param>        <param-name>encoding</param-name>        <param-value>UTF-8</param-value>      </init-param>    </filter>    <filter-mapping>      <filter-name>encodingFilter</filter-name>      <url-pattern>/*</url-pattern>    </filter-mapping>    <!-- Spring監聽器 -->    <listener>      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <!-- Spring MVC servlet -->    <servlet>      <servlet-name>SpringMVC</servlet-name>      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>      <init-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:spring-mvc.xml</param-value>      </init-param>      <load-on-startup>1</load-on-startup>      <async-supported>true</async-supported>    </servlet>    <servlet-mapping>      <servlet-name>SpringMVC</servlet-name>      <url-pattern>/</url-pattern>    </servlet-mapping>    <!--log4j日誌-->    <context-param>      <param-name>log4jConfigLocation</param-name>      <param-value>classpath:log4j.properties</param-value>    </context-param>  </web-app>

稍微來說明一下吧。<display-name>ssm</display-name>工程名。下面這個，springcontext的配置文件，很重要，一般把這個配置文件獨立出去，方便管理，事實上你寫到web.xml裡面來也是沒有什麼問題的。但是我沒有試過。有興趣了解一下？然後告訴我？

  <context-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:./spring-cfg.xml</param-value>    </context-param>

接下來就是編碼過濾器。事實上就是一個filter，因為Tomcat的默認編碼不是utf-8 所以為了保證編碼的一致，使用這個編碼過濾器，<filter-mapping>代表的過濾器的生效路徑。

  <filter>      <filter-name>encodingFilter</filter-name>      <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>      <async-supported>true</async-supported>      <init-param>        <param-name>encoding</param-name>        <param-value>UTF-8</param-value>      </init-param>    </filter>    <filter-mapping>      <filter-name>encodingFilter</filter-name>      <url-pattern>/*</url-pattern>    </filter-mapping>

接下來就是spring的監聽器了，**ContextLoaderListener的作用就是啟動Web容器時，自動裝配ApplicationContext.xml的配置資訊。**因為它實現了ServletContextListener這個介面，在web.xml配置這個監聽器，啟動容器時，就會默認執行它實現的方法。也就是說，當web容器初始化的時候，spring 的配置文件ApplicationContext.xml也啟用了，當然我這裡spring的配置文件是spring-cfg.xml。所以監聽器決定我們spring是否啟動。 https://www.cnblogs.com/wuchaodzxx/p/6038895.html

  <!-- Spring監聽器 -->    <listener>      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

繼續下一個,就是servlet的配置了，servlet是web的基礎，我們沒有用框架的時候，就是在web.xml裡面配置servlet-class和servlet-mapping的。那麼這裡的配置就是吧servlet交給springMVC的dispatcherServlet類。適配路徑/* 全部路徑。就是說所有的url都會進入到dispatchservlet類裡面。但你配置 /su/*的時候，那就只能適配/su/ 後面的路徑了

這裡就是實現了整合springMVC，而上面就是整合了spring，那麼你會問mybatis捏，事實上mybatis是後端和數據交互的中間過程，也是說橋樑。那麼我們寫業務的時候才需要用到mybatis，所以mybatis是整合到spring裡面來，也就是說實在spring-cfg.xml裡面配置。

<!-- Spring MVC servlet -->    <servlet>      <servlet-name>SpringMVC</servlet-name>      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>      <init-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:spring-mvc.xml</param-value>      </init-param>      <load-on-startup>1</load-on-startup>      <async-supported>true</async-supported>    </servlet>    <servlet-mapping>      <servlet-name>SpringMVC</servlet-name>      <url-pattern>/</url-pattern>    </servlet-mapping>

那麼接下來就是spring-cfg.xml了，這配置也就是開啟aop，掃描註解開啟，事務開啟。還有整合mybatis，整合就是配置sqlSessionFactory以及掃描mapper。當然你說用xml注入bean也行，我開了註解就注入，然而用xml配置DI我覺得好麻煩，而且又長。打註解比較方便，相比之下。

接下來就是spring-mvc.xml。開啟註解，開啟包掃描註解，包掃描component，主要是掃描controller，處理靜態資源，以及配置處理器，這裡我用的velocity，以前很多人用jsp。我沒有導jstl的jar包，你要你自己找dependency導進來。再自己配置

<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"         xmlns:context="http://www.springframework.org/schema/context"         xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context.xsd        http://www.springframework.org/schema/mvc        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">            <mvc:annotation-driven>          <mvc:message-converters>                <bean class="org.springframework.http.converter.StringHttpMessageConverter"/>              <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">                  <property name="supportedMediaTypes">                      <list>                          <value>text/html;charset=UTF-8</value>                          <value>application/json;charset=UTF-8</value>                      </list>                  </property>              </bean>          </mvc:message-converters>      </mvc:annotation-driven>            <!--支援多媒體文件上傳-->      <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">          <!--<property name="maxUploadSize" value="10485760"/> &lt;!&ndash; 表示上傳文件最大Size為10M &ndash;&gt;-->          <property name="maxInMemorySize" value="4096" />          <property name="defaultEncoding" value="UTF-8"/>      </bean>      <!--包掃描-->      <context:component-scan base-package="com.su.User.controller" />        <!--開啟註解掃描-->      <mvc:annotation-driven/>      <!--處理靜態資源-->      <mvc:default-servlet-handler/>              <bean id="velocityConfigurer" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">          <property name="resourceLoaderPath" value="/WEB-INF/views"/>          <property name="velocityProperties">              <props>                  <prop key="input.encoding">utf-8</prop>                  <prop key="output.encoding">utf-8</prop>                  <prop key="file.resource.loader.cache">false</prop>                  <prop key="file.resource.loader.modificationCheckInterval">1</prop>                  <prop key="velocimacro.library.autoreload">false</prop>              </props>          </property>      </bean>        <bean class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">          <property name="suffix" value=".vm"/>          <property name="contentType" value="text/html;charset=utf-8"/>          <property name="dateToolAttribute" value="date"/><!--日期函數名稱-->      </bean>        </beans>

到了這裡還沒好，掃描的那些mapper文件沒有，entity也沒有，dao也沒有，這些沒有還會會報錯。繼續看下去，你可以用mybatis-generator逆向，不會的自行百度。

我這裡簡單說一下。

主要是pom.xml的那裡吧mybatis-generator導進來。

然後配置xml，再配置maven

配置文件generatorConfig.xml為

<?xml version="1.0" encoding="UTF-8" ?>  <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"          "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >  <generatorConfiguration>        <!--classPathEntry:資料庫的JDBC驅動 -->      <classPathEntry              location="D:maven3mavenrepositorymysqlmysql-connector-java5.1.45mysql-connector-java-5.1.45.jar" />        <context id="MysqlTables" targetRuntime="MyBatis3">            <!-- 注意這裡面的順序確定的，不能隨變更改 -->          <!-- 自定義的分頁插件 <plugin type="com.deppon.foss.module.helloworld.shared.PaginationPlugin"/> -->            <!-- 可選的（0 or 1） -->          <!-- 注釋生成器 -->          <commentGenerator>              <!-- 是否去除自動生成的注釋 true：是 ： false:否 -->              <property name="suppressAllComments" value="true" />          </commentGenerator>            <!-- 必須的（1 required） -->          <!--資料庫連接的資訊：驅動類、連接地址、用戶名、密碼 -->          <jdbcConnection driverClass="com.mysql.jdbc.Driver"                          connectionURL="jdbc:mysql://localhost:3306/project-manager"                          userId="root" password="root">          </jdbcConnection>            <!-- 可選的（0 or 1） -->          <!-- 類型轉換器或者加類型解析器 -->          <!-- 默認false，把JDBC DECIMAL 和 NUMERIC 類型解析為 Integer true，把JDBC DECIMAL 和              NUMERIC 類型解析為java.math.BigDecimal -->          <javaTypeResolver>              <property name="forceBigDecimals" value="false" />          </javaTypeResolver>              <!-- 必須的（1 required） -->          <!-- java模型生成器 -->          <!-- targetProject:自動生成程式碼的位置 -->          <javaModelGenerator targetPackage="com.su.User.entity"                              targetProject="D:ProjectCollectionideassmsrcmainjava"                               >              <!-- TODO enableSubPackages:是否讓schema作為包的後綴 -->              <property name="enableSubPackages" value="true" />              <!-- 從資料庫返回的值被清理前後的空格 -->              <property name="trimStrings" value="true" />          </javaModelGenerator>            <!-- 必須的（1 required） -->          <!-- map xml 生成器 -->          <sqlMapGenerator targetPackage="com.su.User.dao"                           targetProject="D:ProjectCollectionideassmsrcmainjava">              <property name="enableSubPackages" value="true" />          </sqlMapGenerator>            <!-- 可選的（0 or 1） -->          <!-- mapper 或者就是dao介面生成器 -->          <javaClientGenerator targetPackage="com.su.User.dao"                               targetProject="D:ProjectCollectionideassmsrcmainjava"                               type="XMLMAPPER">              <property name="enableSubPackages" value="true" />          </javaClientGenerator>            <!-- 必須的（1...N） -->          <!-- pojo 實體生成器 -->          <!-- tableName:用於自動生成程式碼的資料庫表；domainObjectName:對應於資料庫表的javaBean類名 -->          <!-- schema即為資料庫名 可不寫 -->          <table  tableName="user" domainObjectName="User"                  enableInsert="true" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"                  enableSelectByExample="false" selectByExampleQueryId="false">              <!-- 忽略欄位 可選的（0 or 1） -->              <!-- <ignoreColumn column="is_use" /> -->              <!--//無論欄位是什麼類型，生成的類屬性都是varchar。 可選的（0 or 1） 測試無效 -->              <!-- <columnOverride column="city_code" jdbcType="VARCHAR" /> -->          </table>            </context>  </generatorConfiguration>

逆向生成後，自己寫一些controller測試吧。到這裡已經搭建好了

如果報錯，查看報錯資訊，先翻譯找錯，不行再百度吧。

3.整合logback+lombok

首先是pom.xml導包，這裡只是pom.xml的一部分，這是logback需要的一些包

 <!-- 日誌文件管理包 -->          <!-- log start -->            <!--logback-->          <dependency>              <groupId>org.slf4j</groupId>              <artifactId>slf4j-api</artifactId>              <version>${slf4j.version}</version>          </dependency>          <dependency>              <groupId>ch.qos.logback</groupId>              <artifactId>logback-core</artifactId>              <version>1.1.6</version>          </dependency>          <dependency>              <groupId>ch.qos.logback</groupId>              <artifactId>logback-classic</artifactId>              <version>1.1.6</version>          </dependency>          <dependency>              <groupId>ch.qos.logback</groupId>              <artifactId>logback-access</artifactId>              <version>1.1.2</version>          </dependency>          <dependency>              <groupId>commons-logging</groupId>              <artifactId>commons-logging</artifactId>              <version>1.2</version>          </dependency>            <dependency>              <groupId>commons-codec</groupId>              <artifactId>commons-codec</artifactId>              <version>1.10</version>          </dependency>            <dependency>              <groupId>log4j</groupId>              <artifactId>log4j</artifactId>              <version>1.2.17</version>          </dependency>          <dependency>              <groupId>org.logback-extensions</groupId>              <artifactId>logback-ext-spring</artifactId>              <version>0.1.4</version>          </dependency>          <dependency>              <groupId>org.projectlombok</groupId>              <artifactId>lombok</artifactId>              <version>1.16.6</version>          </dependency>          <!--end-->

配置logback，新建一個logback.xml,這裡面有些地方需要改寫自己項目的配置，比如日誌存放的文件的位置，默認是Tomcat的啟動的那個盤的目錄下，我的配置是這樣子的。logback的好處，自己去百度吧，這裡是採用error級別和info級別的區分，有特定需求自己搞吧。

<?xml version="1.0" encoding="UTF-8"?>  <configuration>      <property name="LOG_HOME" value="/logs/ssm/" />        <appender name="Console" class="ch.qos.logback.core.ConsoleAppender">          <encoder>              <pattern>%d{H:mm} %-5level [%logger{16}] %msg%n</pattern>          </encoder>      </appender>        <appender name="normalLog"                class="ch.qos.logback.core.rolling.RollingFileAppender">          <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">              <FileNamePattern>${LOG_HOME}/web.normal.%d{yyyy-MM-dd}.log              </FileNamePattern>              <MaxHistory>30</MaxHistory>          </rollingPolicy>          <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">              <maxFileSize>10MB</maxFileSize>          </triggeringPolicy>          <layout class="ch.qos.logback.classic.PatternLayout">              <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{16} - %msg%n              </pattern>          </layout>          <filter class="ch.qos.logback.classic.filter.LevelFilter">              <level>ERROR</level>              <onMatch>DENY</onMatch>              <onMismatch>ACCEPT</onMismatch>          </filter>      </appender>      <appender name="errorLog"                class="ch.qos.logback.core.rolling.RollingFileAppender">          <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">              <FileNamePattern>${LOG_HOME}/web.error.%d{yyyy-MM-dd}.log              </FileNamePattern>              <MaxHistory>30</MaxHistory>          </rollingPolicy>          <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">              <maxFileSize>10MB</maxFileSize>          </triggeringPolicy>          <layout class="ch.qos.logback.classic.PatternLayout">              <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{16} - %msg%n              </pattern>          </layout>          <filter class="ch.qos.logback.classic.filter.LevelFilter">              <level>ERROR</level>              <onMatch>ACCEPT</onMatch>              <onMismatch>DENY</onMismatch>          </filter>      </appender>          <logger name="com.su" level="debug" >          <appender-ref ref="normalLog" />          <appender-ref ref="errorLog" />      </logger>          <root level="info">          <appender-ref ref="Console" />      </root>  </configuration>

然後在web.xml配置logback

  <!--log4j日誌 由於啟用了logback日誌，此配置廢除-->    <!--<context-param>-->      <!--<param-name>log4jConfigLocation</param-name>-->      <!--<param-value>classpath:log4j.properties</param-value>-->    <!--</context-param>-->        <!--logback日誌-->    <context-param>      <param-name>logbackConfigLocation</param-name>      <param-value>classpath:logback.xml</param-value>    </context-param>

4. 整合shiro

首先導包。

創建一個realm，注意這裡只是簡單創建一個realm，其實可以創建多個realm，這個需要看需求，我把程式碼貼出來吧，簡化過的程式碼，有需要可以查看別人的部落格，來進行完善

package com.su.shiro;        import com.su.user.entity.User;  import com.su.user.service.UserService;  import org.apache.shiro.authc.AuthenticationException;  import org.apache.shiro.authc.AuthenticationInfo;  import org.apache.shiro.authc.AuthenticationToken;  import org.apache.shiro.authc.SimpleAuthenticationInfo;  import org.apache.shiro.authz.AuthorizationInfo;  import org.apache.shiro.authz.SimpleAuthorizationInfo;  import org.apache.shiro.realm.AuthorizingRealm;  import org.apache.shiro.subject.PrincipalCollection;    import javax.annotation.Resource;  import java.util.Set;    /**   * @author Veng Su 1344114844@qq.com   * @date 2018/4/12 9:40   */  public class MyRealm extends AuthorizingRealm {      @Resource      private UserService userServiceImpl;        //為當前登錄成功的用戶授予許可權和角色，已經登錄成功了。      protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {          String username=(String) principals.getPrimaryPrincipal();          SimpleAuthorizationInfo authorizationInfo=new SimpleAuthorizationInfo();          //這裡拿到角色名          Set<String> roles = null;          roles.add("user");//賦予user角色，其實你可以放到資料庫裡面，這裡簡化          authorizationInfo.setRoles(roles);          //這裡拿到該角色的許可權          //這裡拿到角色名          Set<String> permissions = null;          permissions.add("select");//賦予user角色許可權，其實你可以放到資料庫裡面，這裡簡化          authorizationInfo.setStringPermissions(permissions);          return authorizationInfo;      }          //驗證當前登錄的用戶，獲取認證資訊。      protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {          String username=(String) token.getPrincipal();//獲取用戶名          User user=new User();//這裡簡化，本來從資料庫拿的          //如果查詢不出來則返回null，不通過驗證，如果查出來，則返回AuthenticationInfo          if(user!=null){              AuthenticationInfo authcInfo =new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(),"myRealm");              return authcInfo;          }else{              return null;          }      }  }

好了，萬事俱備，那麼就要在web.xml裡面註冊這個shiro，shiro是基於filter來搞得，那麼就要在web.xml裡面註冊這個filter

<!--集成shiro-->      <filter>          <filter-name>shiroFilter</filter-name>          <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>          <init-param>              <!-- 該值預設為false，表示聲明周期由SpringApplicationContext管理，設置為true表示ServletContainer管理 -->              <param-name>targetFilterLifecycle</param-name>              <param-value>true</param-value>          </init-param>      </filter>      <filter-mapping>          <filter-name>shiroFilter</filter-name>          <url-pattern>/*</url-pattern>      </filter-mapping>

那麼到這裡，shiro已經集成到spring裡面了

接下來就是使用shiro來做登錄驗證，我去找張流程圖

認證過程

授權過程

然後，我把構建sercurityManager的環境搭建起來吧，簡單點就是用controller調用realm的doGetAuthorizationInfo授權,和doGetAuthenticationInfo驗證，這裡是我的項目的源碼而已，有問題，看著shiro的官方文檔來吧

package com.su.shiro;      import com.su.user.service.UserService;  import org.apache.shiro.authc.AuthenticationException;  import org.apache.shiro.authc.AuthenticationInfo;  import org.apache.shiro.authc.AuthenticationToken;  import org.apache.shiro.authz.AuthorizationInfo;  import org.apache.shiro.authz.SimpleAuthorizationInfo;  import org.apache.shiro.realm.AuthorizingRealm;  import org.apache.shiro.subject.PrincipalCollection;    import javax.annotation.Resource;    /**   * @author Veng Su 1344114844@qq.com   * @date 2018/4/12 9:40   */  public class MyRealm extends AuthorizingRealm {      @Resource      private UserService userServiceImpl;        //為當前登錄成功的用戶授予許可權和角色，已經登錄成功了。      protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {          String username=(String) principals.getPrimaryPrincipal();          SimpleAuthorizationInfo authorizationInfo=new SimpleAuthorizationInfo();  //        authorizationInfo.setRoles(userServiceImpl.getRoles(username));  //        authorizationInfo.setStringPermissions(userServiceImpl.getPermissions(username));          return authorizationInfo;      }          //驗證當前登錄的用戶，獲取認證資訊。      protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {          String username=(String) token.getPrincipal();//獲取用戶名  //        User user=userServiceImpl.getByUsername(username);  //        if(user!=null){  //            AuthenticationInfo authcInfo =new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(),"myRealm");  //            return authcInfo;  //        }else{  //            return null;  //        }          return null;      }  }
