3.2添加三个配置文件并配置相关参数

web.xml文件

 <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <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:applicationContext-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>

 

applicationContext.xml文件

 <!-- 读取properties文件org.springframework.beans.factory.config.PlaceholderConfigurerSupport  -->
        <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

    <!-- aop激活自动代理功能 -->
    <aop:aspectj-autoproxy proxy-target-class="true"/>
    
    
    <!-- 事务处理器 -->
    <bean id="txManage" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

 

 

applicationContext-mvc.xml文件

<context:component-scan base-package="com.diancan.controller"/>
    <!-- 配置SpringMVC的视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="http://www.mamicode.com/WEB-INF/jsp/"/>
        <property name="suffix" value="http://www.mamicode.com/.jsp"/>
    </bean>

 

 

mybatis-config.xml文件

<settings> 
        <setting name="cacheEnabled" value="http://www.mamicode.com/true" /><!-- 全局映射器启用缓存 -->   
        <setting name="useGeneratedKeys" value="http://www.mamicode.com/true" /> 
        <setting name="defaultExecutorType" value="http://www.mamicode.com/REUSE" />

        <!-- 分页 -->
        <typeAlias type="com.diancan.entity.Page" alias="Page"/>
    </typeAliases>
