struts2+mybatis+spring框架整合
近期公司要开发新的项目，要用struts2+ibatis+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+ibatis+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"?><beansxmlns="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"value="classpath:com/test/sqlMapper/mybatis_config.xml" /> <property name="dataSource" ref="dataSource" /> </bean> <bean id="loginDao" value="com.test.dao.ILoginDao"/><property name="sqlSessionFactory" ref="sqlSessionFactory" /></bean><bean id="loginAction" 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=loginjdbc.driver=com.microsoft.sqlserver.jdbc.SQLServerDriverjdbc.user=sajdbc.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
