本文详细介绍了配置Web应用的基础文件，包括web.xml、applicationContext.xml等，并深入讲解了数据库连接、数据模板、SQL映射文件、Struts配置、JavaBean类、DAO层、Service层、Action层等关键组件的配置与实现。通过实例代码展示了如何搭建完整的Web应用框架，覆盖从配置到实际业务逻辑的全过程。

配置web.xml

<?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_3_0.xsd" id="WebApp_ID" version="3.0">

	<servlet-mapping>
		<servlet-name>action</servlet-name>

	</servlet-mapping>
  
  
</web-app>

配置applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"

		<property name="dao" ref="dao" />
	</bean>
	
	
	<bean name="dao" class="com.dao.UserDaoImpl" parent="abstractDao"></bean>

</beans>

配置sqlmap.xml

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

	<select id="select_user_list" parameterClass="hashmap" resultClass="hashmap">
		select * from user
	</select>
	
	
</sqlMap>

配置SqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMapConfig      
    PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"

javabean类

TestForm.java

package com.action;

	 * javabean类，也就是实体类。
	 */
	private static final long serialVersionUID = 1L;

dao类

UserDaoImpl.java

package com.dao;

import java.util.HashMap;
import java.util.List;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;

public class UserDaoImpl extends SqlMapClientDaoSupport {
	/*
		dao层，也就是持久层。
	*/

service类

TestService.java

package com.service;

import java.util.HashMap;

import org.apache.struts.actions.DispatchAction;

import com.dao.UserDaoImpl;

public class TestService extends DispatchAction {

/*	
	业务层，也就是service层。

action类

TestAction.java

package com.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
