配置文件:
spring和mybatis的整合
- 配置service層包掃描
- 配置連接池數據源
- 配置mybatis的核心類（用於整合）
- 配置mybatis的映射掃描器（用於整合）
- 配置mybatis的分頁插件
- 配置事務管理

<!–主程式對應的配置文件–>
<!–開啟bean註解掃描–>
<context:component-scan base-package=”com.XXX.service”/>
<!–載入properties文件–>
<context:property-placeholder location=”classpath*:jdbc.properties”/>
<!–數據源–>
<bean id=”dataSource” class=”com.alibaba.druid.pool.DruidDataSource”>
<property name=”driverClassName” value=”${jdbc.driver}”/>
<property name=”url” value=”${jdbc.url}”/>
<property name=”username” value=”${jdbc.username}”/>
<property name=”password” value=”${jdbc.password}”/>
</bean>
<!–整合mybatis到spring中–>
<bean class=”org.mybatis.spring.SqlSessionFactoryBean”>
<property name=”dataSource” ref=”dataSource”/>
<property name=”typeAliasesPackage” value=”com.itheima.domain”/>
<property name=”plugins”><!–分頁插件–>
<array>
<bean class=”com.github.pagehelper.PageInterceptor”>
<property name=”properties”>
<props>
<prop key=”helperDialect”>mysql</prop>
<prop key=”reasonable”>true</prop>
</props>
</property>
</bean>
</array>
</property>
</bean>
<!–映射掃描–>
<bean class=”org.mybatis.spring.mapper.MapperScannerConfigurer”>
<property name=”basePackage” value=”com.itheima.dao”/>
</bean>
<!–開啟註解式事務–>
<tx:annotation-driven transaction-manager=”txManager”/>
<!–事務管理器–>
<bean id=”txManager” class=”org.springframework.jdbc.datasource.DataSourceTransactionManager”>
<property name=”dataSource” ref=”dataSource”/>
</bean>
</beans>
SpringMVC環境配置
- 註解的掃描
- 處理器適配器和處理器映射器
- 釋放靜態資源
<?xml version=”1.0″ encoding=”UTF-8″?>
<beans xmlns=”//www.springframework.org/schema/beans”
xmlns:context=”//www.springframework.org/schema/context”
xmlns:mvc=”//www.springframework.org/schema/mvc”
xmlns:xsi=”//www.w3.org/2001/XMLSchema-instance”
xsi:schemaLocation=”//www.springframework.org/schema/beans //www.springframework.org/schema/beans/spring-beans.xsd
//www.springframework.org/schema/mvc //www.springframework.org/schema/mvc/spring-mvc.xsd
//www.springframework.org/schema/context //www.springframework.org/schema/context/spring-context.xsd”>
<mvc:annotation-driven/>
<context:component-scan base-package=”com.xxxx.controller”/>
<mvc:default-servlet-handler/>
</beans>
注意: <mvc:default-servlet-handler/>這個釋放靜態資源路不配置也是可以的 在web.xml中可以攔截*.do的請求是一樣的效果
web.xml文件配置（1+1+1）
<?xml version=”1.0″ encoding=”UTF-8″?>
<web-app xmlns=”//xmlns.jcp.org/xml/ns/javaee”
xmlns:xsi=”//www.w3.org/2001/XMLSchema-instance”
xsi:schemaLocation=”//xmlns.jcp.org/xml/ns/javaee
//xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd”
version=”3.1″>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:applicationContext.xml</param-value>
</context-param>
<!–啟動伺服器時，通過監聽器載入spring運行環境–>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<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>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<servlet>
<servlet-name>DispatcherServlet</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>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>(這裡就可以寫*.do那麼就不需要配置釋放靜態資源了)
</servlet-mapping>
</web-app>
到此再寫dao service controller 層就可以了 訪問資料庫測試一下就完成了ssm的基礎搭建
