以下是一个简单的ssm项目：如果中途报错，肯定是tomcat配置或者数据库配置有问题，在程序中注意将包名等配置换成自己的。数据库表需要提前建好，并加入数据，注意表结构要和实体对象对应。

1.开发条件：eclipse + comcat7.0

2.创建一个Dynamic Web Project项目，大概的目录结构。

3.jar包如下：

4.页面访问结果：http://localhost:8080/spring001/list.action

 

下面开始上代码：

1.UserDao

package cn.mr.li.dao;import java.util.List;import cn.mr.li.entity.User;public interface UserDao {    List
     
       getUser();}
     

2.UserDaoImpl

package cn.mr.li.dao.impl;import java.util.List;import org.mybatis.spring.support.SqlSessionDaoSupport;import cn.mr.li.dao.UserDao;import cn.mr.li.entity.User;public class UserDaoImpl extends SqlSessionDaoSupport implements UserDao {        @Override    public List
     
       getUser() {        return this.getSqlSession().selectList("cn.mr.li.entity.user.mapper.getAll");    }}
     

3.userService

package cn.mr.li.service;import java.util.List;import cn.mr.li.entity.User;public interface UserService {    List
     
       getAll();}
     

4.userServiceImpl

package cn.mr.li.service.impl;import java.util.List;import cn.mr.li.dao.UserDao;import cn.mr.li.entity.User;import cn.mr.li.service.UserService;public class UserServiceImpl implements UserService {    private UserDao userDao;        @Override    public List
     
       getAll() {        return userDao.getUser();    }    public UserDao getUserDao() {        return userDao;    }    public void setUserDao(UserDao userDao) {        this.userDao = userDao;    }}
     

5.user

package cn.mr.li.entity;public class User {    private int id;        private String name;        private int age;    public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public int getAge() {        return age;    }    public void setAge(int age) {        this.age = age;    }    public User(int id, String name, int age) {        super();        this.id = id;        this.name = name;        this.age = age;    }        public User() {    }}

6.user-mapper.xml

     
         
              select * from user    
     

7.UserAction

       list;    private UserService userService;        public String list(){        list = userService.getAll();        return "success";    }        public List
      
        getList() {        return list;    }    public void setList(List
       
         list) {        this.list = list;    }    public UserService getUserService() {        return userService;    }    public void setUserService(UserService userService) {        this.userService = userService;    }}
