struts2+mybatis+spring框架整合

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"?>
 <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">


     <bean id="propertyConfigurer"
         class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
         <property name="location">
             <value>/WEB-INF/configs/sqlServer.propertiesvalue>
         property>
     bean>


     <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     

 jdbcjdbc.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" ?>
 >
 <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"?>
 >
 <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>contextConfigLocationparam-name>
     <param-value>/WEB-INF/classes/applicationContext.xmlparam-value>
 context-param>

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

   <filter>
     <filter-name>struts2filter-name>
     <filter-class>
         org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
     filter-class>

   filter>

   <filter-mapping>
     <filter-name>struts2filter-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   

     "login" method="post">
     "username" label="用户名：">
     "password" label="密码：">
     "提交">

 
     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
