最近公司搭建一个应用系统，由于本人好多年没有用到struts、spring和mybatis（以前叫abatis），一切都要从头开始，只能边查文档边开发。邻近年末，对前期的工作大概总结一下，作为资料保存。

## 1、开源框架 ##

struts2- 2.3.15.3+spring3.2.4+mybatis-3.2.3

## 2、下载所需要的包 ##

有的包不需要，可适当删除

![SouthEast][]

## 3、建表 ##

以mysql为例，建库Test，并执行下面sql

CREATE TABLE T\_TEST (

id  varchar(12),

name varchar(50)

)

## 4、新建工程工程名为：Test ##

包结构和配置文件

![Image 1][]![SouthEast 1][]

包结构

action 处理前台交互

bean   实体类

dao    负责和数据库交互

mapper 是mybatis的配置文件

services 是业务逻辑接口

services.impl是业务逻辑实现类

## 5、配置文件 ##

Web.xml配置文件

Stuts2配置文件struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd">

    	<constant name="struts.objectFactory" value="spring" />

    		namespace="/">
    		
    	</package>
    	
    	<include file="struts-test.xml"></include>
    </struts>

Mybatis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>
          
          
    
    </configuration>

日志采用log4j，配置文件log4j.properties

log4j.rootLogger=ERRO, CONSOLE,ZHOU
    
    log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
    log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout

    log4j.appender.ZHOU.layout.conversionPattern=%d [%t] %-5p %c(%L) - %m%n
    log4j.appender.ZHOU.MaxFilZHOUize=1000KB
    log4j.appender.ZHOU.MaxBackupIndex=10
    
    log4j.logger.com.zhou=INFO,ZHOU
    
    
    log4j.logger.org.springframework=ERROR,ZHOU
    log4j.logger.org.springframework.jdbc.support=DEBUG
    log4j.logger.org.springframework.scheduling=DEBUG
    log4j.logger.java.sql.Connection=DEBUG

## 6、验证 ##

我们以数据从前台添加保存到数据库中为例

在WebRoot下新建test.jsp

<%@ page contentType="text/html; charset=UTF-8"%>
    <html>
    <head>
    <title></title>
    <script type="text/javascript">
    	function insertTest() {
    		var myform = document.forms[0];
    		myform.action = "Test!save.action";
    		myform.method = "post";
    		myform.submit();
    	}
    </script>
    
    
    </head>
    <body>
    	<h1>样例</h1>
    	<hr>
    	<form name="myform">
    		id: <input type="text" name="test.id"> <br> 
    		name： <input type="text" name="test.name"> <br> 
    		<input type="button" name="btninsert" οnclick="insertTest()" value="增加" />
    	</form>
    </body>
    </html>

在包bean新建Test.java实体类

package com.zhou.action;
    
    import com.zhou.bean.Test;
    import com.zhou.services.TestService;
    
    /**
     * @author zhouzhenlong
     * @date Sept 18, 201212:55:36 PM
     * @description
     * @version V1.0
     */
    public class TestAction {
    	private static final long serialVersionUID = 1L;
    	/**
    	 * 注入service
    	 */
    	private TestService testService;
    	private Test test;
    
    	/**
    	 * 保存Test对象
    	 * 
    	 * @return
    	 */
    	public String save() {
    		testService.save(test);
    		return "success";
    	}
    
    	public void setTestService(TestService testService) {
    		this.testService = testService;
    	}
    
    	public void setTest(Test test) {
    		this.test = test;
    	}
    
    	public Test getTest() {
    		return test;
    	}
    
    }

在包services创建接口TestService.java

package com.zhou.services;
    
    import com.zhou.bean.Test;
    
    /**
     * @author zhouzhenlong
     * @date Sept 18, 201212:55:36 PM
     * @description
     * @version V1.0
     */
    public interface TestService {
    	/**
    	 * 保存Test对象
    	 * 
    	 * @param test
    	 */
    	public void save(Test test);
    }

在包services.impl创建接口的实现类TestServiceImpl.java

package com.zhou.services.impl;
    
    import com.zhou.bean.Test;
    import com.zhou.dao.TestDao;
    import com.zhou.services.TestService;
    /**
     * @author zhouzhenlong
     * @date Sept 18, 201212:55:36 PM
     * @description 
     * @version V1.0
     */
    public class TestServiceImpl implements TestService {
    
    	private TestDao testDao;
    
    	public void setTestDao(TestDao testDao) {
    		this.testDao = testDao;
    	}
    
    	public void save(Test test) {
    		testDao.insertTest(test);
    	}
    }

在包dao下创建TestDao.java

package com.zhou.dao;
    
    import com.zhou.bean.Test;
    
    /**
     * @author zhouzhenlong
     * @date Sept 18, 201212:55:36 PM
     * @description
     * @version V1.0
     */
    
    public interface TestDao {
    	/**
    	 * 插入
    	 * 
    	 * @param test
    	 */
    	public void insertTest(Test test);
    }

在包mapper先创建mybatis的配置文件test-mapper.xml

注意namespace要和实际映射的接口dao的路径相同

<?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.zhou.dao.TestDao">
    	<insert id="insertTest" parameterType="com.zhou.bean.Test" >
    		insert into t_test(id,name) values (#{id},#{name})
    	</insert>
    </mapper>

创建配置文件applicationContext-beans.xml，负责spring依赖注入

创建配置文件struts-test.xml，负责struts2的访问和跳转

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd">
    
    <struts>
       
    	<package name="MyActions" extends="struts-default">     
            <action name="Test!*" class="testAction" method="{1}">
    			<result name="success">/index.jsp</result>
    		</action>
        </package>
    
    </struts>

部署到tomcat下访问[http://localhost:8080/Test/test.jsp][http_localhost_8080_Test_test.jsp]

保存到数据库，成功！！！
