导入jar包:

创建实体类:

数据访问层接口及其实现

创建service

配置ApplicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

        ">
   <!-- 01.C3p0 数据源 -->
   <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <!-- 设值注入，本质上使用的是类的set方法 -->

     <property name="user" value="${jdbc.username}"></property>

      <aop:advisor advice-ref="txAdvice" pointcut-ref="pointCut"/>
      
   </aop:config>
  
</beans>

配置数据库连接信息

创建struts.xml

 因为是web端:所以要配置web.xml来加载资源文件

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
  <display-name></display-name>
  
  <!--指定路径 applicationContext.xml  -->
  <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  
  <!-- 监听器：在应用程序加载启动的时候，spring容器自动构建 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <!-- 核心过滤器 -->
  <filter>
    <filter-name>struts</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  
  <filter-mapping>
    <filter-name>struts</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  
  
  
  
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

 最后创建页面进行访问:

add.jsp

成功页面:

index.jsp
