SpringMVC+Spring+mybatis+maven+搭建多模組框架前後端分離開發框架的完整demo,拿走不謝。——猿實戰02
猿實戰是一個原創系列文章，通過實戰的方式，採用前後端分離的技術結合SpringMVC Spring Mybatis,手把手教你擼一個完整的電商系統，跟著教程走下來，變身猿人找到工作不是問題。想要一起實戰嗎？，關注公主號猿人工廠，獲取基礎程式碼，手把手帶你開發屬於自己的電商系統。
從今天開始，我們將進入猿實戰的階段，實現一個前後端分離的電商系統，沒有開發框架怎麼行？今天是第一個系列，猿人君將帶你搭建後端開發框架。
創建應用父模組
父模組負責控制整個應用的結構,因為pzmall-basic作為父項目的存在，無需編寫程式碼,記得在創建完成後，刪除項目下的src目錄。
創建子模組
考慮到我們需要構建一個B2C(兼容商家端的應用)我們的應用按照程式碼職責的劃分，我們的應用暫時涉及到一下幾個模組。
pzmall-basic-common:負責編寫項目公用的一些內容，比如工具類。
pzmall-basic-domain:負責項目涉及的實體內容編寫。
pzmall-basic-dao:負責數據持久層的內容編寫。
pzmall-basic-service：負責業務邏輯層的內容編寫。
pzmall-basic-search-util：負責項目搜索引擎工具相關的內容編寫。
pzmall-basic-web:負責項目網站端業務內容編寫。
pzmall-basic-manweb:負責項目運營管理端業務內容編寫。
接下來我們一起來創建子項目pzmall-basic-common。
接下來，以葫蘆畫瓢，建立pzmall-basic-domain、pzmall-basic-dao、pzmall-basic-service、pzmall-basic-search-util幾個子模組，最後得到如下結果。
由於pzmall-basic-web和pzmall-basic-manweb屬於web應用，在創建時有所區別，在選擇maven項目類型時記得選擇正確的archetype,org.apache.maven.archetypes:maven-archetype-webapp.
完成後，並在模組的src/main目錄下建立java和resources兩個目錄。
最後項目的整體結果效果如下，為了測試下效果，編譯下項目。
調整項目依賴
就項目模組之間的依賴關係而言，pzmall-basic-common和pzmall-basic-serch-util由於編寫的是工具類，相對獨立，不依賴於其它模組。pzmall-basic-domain、pzmall-basic-dao、pzmall-basic-service、三者的依賴是存在關聯關係的，pzmall-basic-service依賴pzmall-basic-dao，pzmall-basic-dao依賴pzmall-basic-domain。而之前提及的pzmall-basic-common和 pzmall-basic-serch-util更多的會在service層被使用。所以，pzmall-basic-service會依賴pzmall-basic-common和pzmall-basic-serch-util。注意哈，pzmall-basic-domain要盡量保持乾淨，不要和工具類扯上什麼關係，否則對今後的架構方面的擴展，是不友好的。而pzmall-basic-web和pzmall-basic-manweb作為項目最終要部署的war包，依賴pzmall-basic-service就可以了。
接下來我們調整引入各個層面所需要的依賴，搭建我們項目開發所需要的框架。

搭建開發框架
1.在pzmall-basic-dao模組的src/main目錄下建立resources/mybatis目錄,並在mybaits目錄下建立SqlMapConfig.xml文件以及mapper目錄。
SqlMapConfig.xml下用於配置mybatis全局相關的一些屬性，以及載入哪些mapper配置文件，mapper目錄下未來將按模組存放相干的mapper文件。
2.在pzmall-basic-manweb目錄的resources目錄下分別建立spring和config兩個目錄。並在resources目錄下建立applicationContext.xml文件。如下圖所示。
3.整合mybatis，在spring目錄中建立文件，spring-dao.xml並輸入如下內容。
<?xmlversion="1.0" encoding="UTF-8"?>

<property name="sqlSessionFactoryBeanName"value="mybatisSqlSessionFactory"/>
<propertyname="basePackage" value="com.pz.basic.mall.dao" />
</bean>
</beans>
4.配置事務相關的內容，在spring目錄中建立文件，spring-tx.xml並輸入如下內容。
<?xmlversion="1.0" encoding="UTF-8"?>
<beansxmlns="//www.springframework.org/schema/beans"
xmlns:xsi="//www.w3.org/2001/XMLSchema-instance"xmlns:p="//www.springframework.org/schema/p"

<propertyname="dataSource" ref="dataSource" />
</bean>
<!-- 開啟事務控制的註解支援 -->
<tx:annotation-driventransaction-manager="transactionManager"/>
</beans>
5.配置SpringMVC相關內容，先在spring目錄中建立文件spring-service.xml備用，然後再建立一個springmvc.xml文件，並在文件中輸入如下內容。

6.由於我們打算使用前後端分離的方式來開發項目，需要解決跨域問題，我們使用了攔截器的方式來處理這個問題，也在springMVC中做了相應的配置。在pzmall-basic-manweb模組中編寫程式碼。
package com.pz.basic.mall.interceptor;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.List;
/**
* 處理跨域請求
*/
public classCommonInterceptor implements HandlerInterceptor {
private List<String> excludedUrls;
public List<String> getExcludedUrls(){
return excludedUrls;
}
public voidsetExcludedUrls(List<String> excludedUrls) {
this.excludedUrls = excludedUrls;
}
/**
*
* 在業務處理器處理請求之前被調用如果返回false
* 從當前的攔截器往回執行所有攔截器的afterCompletion(),
* 再退出攔截器鏈, 如果返回true 執行下一個攔截器,
* 直到所有的攔截器都執行完畢再執行被攔截的Controller
* 然後進入攔截器鏈,
* 從最後一個攔截器往回執行所有的postHandle()
* 接著再從最後一個攔截器往回執行所有的afterCompletion()
*
* @param request
*
* @param response
*/
public boolean preHandle(HttpServletRequestrequest, HttpServletResponse response,
Object handler)throws Exception {
response.setHeader("Access-Control-Allow-Origin","*");
response.setHeader("Access-Control-Allow-Methods", "POST,GET, PUT, OPTIONS, DELETE, PATCH");
response.setHeader("Access-Control-Max-Age","3600");
response.setHeader("Access-Control-Allow-Headers","X-Token, Origin, X-Requested-With, Content-Type, Accept");
response.setHeader("Access-Control-Allow-Credentials","true");
response.setHeader("XDomainRequestAllowed","1");
return true;
}
// 在業務處理器處理請求執行完成後,生成視圖之前執行的動作
public void postHandle(HttpServletRequestrequest, HttpServletResponse response, Object handler,
ModelAndViewmodelAndView) throws Exception {
}
/**
*
* 在DispatcherServlet完全處理完請求後被調用
* 當有攔截器拋出異常時,
* 會從當前攔截器往回執行所有的攔截器的afterCompletion()
*
* @param request
*
* @param response
*
* @param handler
*
*/
public voidafterCompletion(HttpServletRequest request, HttpServletResponse response,
Object handler,Exception ex) throws Exception {
}
}
7.修改pzmall-basic-manweb模組中的resources/config目錄下增加db.properties文件，加入資料庫相關的配置。
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://127.0.0.1:3306/pz_mall_basic?useUnicode=true&characterEncoding=UTF-8 jdbc.username=root jdbc.password=123456
8.在resources目錄下新增log4j.properties文件，增加日誌相關配置。
log4j.rootLogger=trace,console
logging.level.com.pz.mall.dao=DEBUG
log4j.appender.console= org.apache.log4j.ConsoleAppender
log4j.appender.console.Target= System.out
log4j.appender.console.layout= org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=[%-5p][%d{yyyy-MM-dd HH:mm:ss}]%m%n
log4j.logger.com.ibatis=DEBUG
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
log4j.logger.Java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
9.修改pzmall-basic-manweb模組中的web.xml文件，增加應用啟動相關配置：
<?xmlversion="1.0" encoding="UTF-8"?>
<web-appxmlns:xsi="//www.w3.org/2001/XMLSchema-instance"
xmlns="//java.sun.com/xml/ns/javaee"
xsi:schemaLocation="//java.sun.com/xml/ns/javaee//java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
<!-- 解決post亂碼 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 指定載入的配置文件，通過參數contextConfigLocation載入 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
</web-app>
到此為止，我們項目的開發框架搭建完畢。
