Spring+springmvc+mybatis整合案例

今天在整合过程中发生了很多问题，根本原因在于整合jar不完整，导致的NotFoundClass报错，这个错误很经典，一旦jar有误就会发生，我在这里粘贴上我的项目源码，以便于提供大家参考。
源码下载地址：http://download.csdn.net/detail/u013821825/9546000
项目中我用的是spring3.1.2+mybatis3.0.5整合的

项目结构：

1、数据准备

create table CREATE TABLE `emp` ( `id` int(10) NOT NULL, `name` varchar(20) DEFAULT NULL, `age` int(3) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 INSERT INTO `test`.`emp`(`id`,`name`,`age`) VALUES ( '1','xsx','24');
INSERT INTO `test`.`emp`(`id`,`name`,`age`) VALUES ( '2','mpt','23');

2、实体类

package org.xsx.entity;

public class Emp {
    private Integer id;
    private String name;
    private Integer age;
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }


}

3、映射Mapper配置文件

<?xml version="1.0" encoding="UTF-8" ?>  
<!DOCTYPE mapper PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN" "http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd">
<mapper namespace="org.xsx.dao.EmpDao">

<select id="findAll" resultType="org.xsx.entity.Emp">
    select id,name,age from emp
</select>

</mapper>

4、映射接口

package org.xsx.dao;

import java.util.List;

import org.xsx.annotation.MyBatisRepository;
import org.xsx.entity.Emp;

/** * DAO组件 * @author xusha * */
@MyBatisRepository
public interface EmpDao {
    public List<Emp> findAll();
}

5、业务控制类

package org.xsx.controller;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.xsx.dao.EmpDao;
import org.xsx.entity.Emp;

@Controller
@RequestMapping("emp")
public class EmpController {
    @Resource
    private EmpDao empDao;

    @RequestMapping("/findEmp.do")
    public String find(Model model){
        List<Emp> list = empDao.findAll();
        model.addAttribute("emps", list);
        return "emp/emp_list";
    }
}

6、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" 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>
        <servlet-name>SpringMvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
    </servlet>

    <servlet-mapping>
        <servlet-name>SpringMvc</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <async-supported>true</async-supported> 
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>

    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>*.do</url-pattern>
    </filter-mapping>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

7、spring位置文件

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

    </bean>

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

    </bean>


</beans>

8、jsp文件

<%@page pageEncoding="utf-8" contentType="text/html;charset=utf-8" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
    <head></head>
    <body>
        <table width="60%" cellpadding="2" cellspacing="0">
            <tr>
                <td>编号</td>
                <td>姓名</td>
                <td>年龄</td>
            </tr>
            <c:forEach items="${emps}" var="e">
            <tr>
                <td>${e.id }</td>
                <td>${e.name }</td>
                <td>${e.age }</td>
            </tr>
            </c:forEach>
        </table>
    </body>
</html>
