本文详细介绍了使用Struts2、MyBatis和Spring框架整合开发Web应用的过程，包括环境搭建、配置文件编写及代码实现等关键步骤。

近期公司要开发新的项目，要用struts2+mybatis+spring框架，所以学习了下，来自己的博客发表下，希望能给大家带来帮助！下

边我把我的myschool开发的源代码以及数据库贴出来！

开发环境 myeclips+tomcate+sql server

开发技术 struts2+mybatis+spring jsp+java

一.创建web项目导入必需的jar文件

二.创建并编写配置文件，配置文件比较多。可能有点繁琐。

1.创建并编写ApplicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans
	xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
	
	<!--配置数据源属性文件  -->
	<bean id="propertyConfigurer"
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="location">
			<value>/WEB-INF/configs/sqlServer.properties</value>
		</property>
	</bean>
	
	<!--配置数据源  -->
	<bean id="dataSource"
		class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName">
			<value>${jdbc.driver}</value>
		</property>
		<property name="url">
			<value>${jdbc.url}</value>
		</property>
		<property name="username">
			<value>${jdbc.user}</value>
		</property>
		<property name="password">
			<value>${jdbc.pwd}</value>
		</property>
	</bean>
	
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
	    <property name="configLocation" value="classpath:com/test/sqlMapper/mybatis_config.xml" />  
	    <property name="dataSource" ref="dataSource" />  
	</bean> 
	
    
    <bean id="loginDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
		<property name="mapperInterface" value="com.test.dao.ILoginDao"/>
		<property name="sqlSessionFactory" ref="sqlSessionFactory" />
	</bean>

	<bean id="loginAction" class="com.test.action.LoginAction">
		<property name="loginDao" ref="loginDao"></property>
	</bean>
</beans>

2.配置数据源当然要有个数据源属性文件了sqlServer.properties

jdbc.url=jdbc:sqlserver://localhost:1433;DatabaseName=login
jdbc.driver=com.microsoft.sqlserver.jdbc.SQLServerDriver
jdbc.user=sa
jdbc.pwd=

我的数据库密码为空pwd当然也要空了。

3.mybatis的配置文件mybatis_config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> 
<configuration>
	<typeAliases>
		<typeAlias alias="userinfo" type="com.test.entity.UserInfo"/>
	</typeAliases>
	<mappers>
		<mapper resource="com/test/sqlMapper/loginMapper.xml"/>
	</mappers>
</configuration>

4.在mybatis_config.xml中的中有个映射文件loginMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> 
<mapper namespace="com.test.dao.ILoginDao">
	
	<resultMap type="userinfo" id="userMap">
		<id property="id" column="id"/>
		<result property="username" column="username"/>
		<result property="password" column="password"/>	
	</resultMap>
	
	<select id="getUser" parameterType="String" resultMap="userMap">
		select * from userinfo where username=#{userName}
	</select>
</mapper>

5.接下来就是web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" 
	xmlns="http://java.sun.com/xml/ns/j2ee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
	http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<context-param>
	<param-name>contextConfigLocation</param-name>
	<param-value>/WEB-INF/classes/applicationContext.xml</param-value>
</context-param>

<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
</listener>

  <filter>  
	<filter-name>struts2</filter-name>  
	<filter-class>  
		org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter   
	</filter-class>  
 
  </filter>  

  <filter-mapping>  
	<filter-name>struts2</filter-name>  
	<url-pattern>/*</url-pattern>  
  </filter-mapping>  

</web-app>

好了所有的配置文件都已经配置好了
三.该写JAVA文件了接口，实体辅助类，还有action

1.写接口 ILoginDao.java

package com.test.dao;

import java.util.List;

public interface ILoginDao {
	public List getUser(String userName);
}

2.实体辅助类UserInfo.java

package com.test.entity;

public class UserInfo {
	
	private int id;
	private String username;
	private String password;
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
}

3.action 类 LoginAction.java

package com.test.action;

import java.util.List;

import com.test.dao.ILoginDao;

public class LoginAction {

	
		private ILoginDao loginDao;
		private String username;
		private String password;
		

		public String getUsername() {
			return username;
		}
		public void setUsername(String username) {
			this.username = username;
		}
		public String getPassword() {
			return password;
		}
		public void setPassword(String password) {
			this.password = password;
		}
		
		public ILoginDao getLoginDao() {
			return loginDao;
		}
		public void setLoginDao(ILoginDao loginDao) {
			this.loginDao = loginDao;
		}
		
		public String execute(){
			String userName = getUsername();
			String password = getPassword();
			System.out.println("userName:"+userName+"\n"+"password:"+password);
			List list = loginDao.getUser(userName);
			if(list.size()>0){
				return "success";
			}else{
				return "error";
			}
			
		}
		
}

四.该写页面了页面有三个如下
1. login.jsp

<body> 
    <s:form action="login" method="post"> 
    <s:textfield name="username" label="用户名："></s:textfield> 
    <s:textfield name="password" label="密码："></s:textfield> 
    <s:submit value="提交"></s:submit> 
    </s:form> 
  </body>

2.success.jsp 就几个字登陆成功
3.error,jsp 就几个字登录失败
五.创建数据库 login 创建表 userinfo 里面就三个字段 id username password 数据库我已经传到这文章里边了，下载后可以直接用

六.好了快启动tomcat看看成功了
