 public class User {
     private String id;
     private String name;
     private Integer age;
     private String address;
     public String getAddress() {

     @Override
     public String toString() {
         return "User [id=" + id + ", name=" + name + ", age=" + age + "]";
     }

 }

MyUser.xml   (mybatis对数据处理)

3.dao层处理

 package cn.itcast.mybatis.dao;

 import java.util.List;

 import cn.itcast.mybatis.domain.User;

 public interface IUserDao {
     public List<User> list();
     public User get(String id);
     public int insert(User u);
     public int update(User u);
     public int deleteById(String id);
 }

daoImpl处理

 package cn.itcast.mybatis.dao;

 import java.util.List;

 import org.mybatis.spring.support.SqlSessionDaoSupport;

 import cn.itcast.mybatis.domain.User;

 public class UserDaoImpl extends SqlSessionDaoSupport implements IUserDao {

     //删除
     public int deleteById(String id) {
         return this.getSqlSession().delete("cn.itcast.mybatis.domain.User.delete",id);
     }

     //新增
     public int insert(User u) {
         return this.getSqlSession().insert("cn.itcast.mybatis.domain.User.create", u);
     }

     //列表
     public List<User> list() {
         return this.getSqlSession().selectList("cn.itcast.mybatis.domain.User.listAll");
     }

     //修改
     public int update(User u) {
         return this.getSqlSession().update("cn.itcast.mybatis.domain.User.update",u);
     }

     //获取对象
     public User get(String id) {
         return (User) this.getSqlSession().selectOne("cn.itcast.mybatis.domain.User.get", id);
     }

 }

4.service层

 package cn.itcast.mybatis.service;

 import java.util.List;

 import cn.itcast.mybatis.domain.User;

 public interface IUserService {
     public List<User> list();
     public User get(String id);
     public int insert(User u);
     public int update(User u);
     public int deleteById(String id);
 }

serviceImpl

 package cn.itcast.mybatis.service;

 import java.util.List;

 import cn.itcast.mybatis.dao.IUserDao;
 import cn.itcast.mybatis.domain.User;

 public class UserServiceImpl implements IUserService {

     private IUserDao userDao;

     }

     public int deleteById(String id) {
         int i = userDao.deleteById(id);
         //测试事务
         int j = 1/0;

     }

     public List<User> list() {
         return userDao.list();
     }

     public int update(User u) {
         return userDao.update(u);
     }

 }

5.action层

 package cn.itcast.mybatis.action;

 import java.util.List;

 import cn.itcast.mybatis.domain.User;
 import cn.itcast.mybatis.service.IUserService;

 import com.opensymphony.xwork2.ActionContext;

         return "actlist";
     }

     public String updateSave(){

         return "actlist";
     }

     public String delete(){
