<?xml version="1.0" encoding="UTF-8"?>
insert into gy_user(USERID,USERNAME,PASSWORD) values(#userid#,#username#,#password#)
delete from gy_user where USERID=#id#
update gy_user set USERID=#userid#,USERNAME=#username#,PASSWORD=#password# where USERID=#userid#
package com.user.model;
public class User {
private int userid;
private String username;
private String password;
public int getUserid() {
return userid;
}
public String getUsername() {
return username;
}
public String getPassword() {
return password;
}
public void setUserid(int userid) {
this.userid = userid;
}
public void setUsername(String username) {
this.username = username;
}
public void setPassword(String password) {
this.password = password;
}
}
三、Action控制层
userAction.java类
package com.user.action;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.user.model.User;
import com.user.service.UserService;
public class userAction extends ActionSupport{
HttpServletRequest request;
private User user;
private UserService userService;
int id;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public UserService getUserService() {
return userService;
}
public void setUserService(UserService userService) {
this.userService = userService;
}
public String insertUser() throws Exception{
userService.insertUser(user);
return "success";
}
//查询用户
public String queryUser() throws Exception{
List userlist=userService.queryUser(user);
System.out.println("userAction--size--"+userlist.size());
for(int i=0;i
四、Service接口+实现（业务逻辑层）
1、Service接口
UserService.java类
package com.user.service;
import java.util.List;
import com.user.model.User;
public interface UserService {
//添加用户
public void insertUser(User user) throws Exception;
//查询用户
public List queryUser(User user) throws Exception;
//查询用户by id
public User queryUserById(int id) throws Exception;
//删除用户
public void deleteUser(int id) throws Exception;
//修改用户
public void updateUser(User user) throws Exception;
}
2、Service接口实现
UserServiceImpl.java类
package com.user.service.impl;
import java.util.List;
import com.user.model.User;
import com.user.service.UserService;
import com.user.dao.UserDao;
public class UserServiceImpl implements UserService{
private UserDao userdao=null;
public UserDao getUserdao() {
return userdao;
}
public void setUserdao(UserDao userdao) {
this.userdao = userdao;
}
//添加用户
public void insertUser(User user) throws Exception {
// TODO Auto-generated method stub
System.out.println("插入数据User开始--->UserService");
userdao.insertUser(user);
System.out.println("插入数据User结束--->UserService");
}
//查询用户
public List queryUser(User user) throws Exception{
System.out.println("查询数据User开始--->UserService");
List userlist=userdao.queryUser(user);
System.out.println("UserService--size--"+userlist.size());
for(int i=0;iUserService");
return userlist;
}
//删除用户
public void deleteUser(int id) throws Exception {
// TODO Auto-generated method stub
System.out.println("删除数据User开始--->UserService");
userdao.deleteUser(id);
System.out.println("删除数据User开始--->UserService");
}
//查询用户by id
public User queryUserById(int id) throws Exception {
// TODO Auto-generated method stub
System.out.println("查询数据BY ID开始--->UserService"+"---"+id);
User user=userdao.queryUserById(id);
System.out.println("查询数据BY ID结束--->UserService"+"---"+id);
return user;
}
//修改用户
public void updateUser(User user) throws Exception {
// TODO Auto-generated method stub
System.out.println("更新数据User开始--->UserService");
userdao.updateUser(user);
System.out.println("更新数据User开始--->UserService");
}
}
五、DAO接口+实现（持久层）
1、DAO接口
UserDao.java类
package com.user.dao;
import java.util.List;
import com.user.model.User;;
public interface UserDao {
//添加用户
public void insertUser(User user);
//查询用户
public List queryUser(User user);
//查询用户by id
public User queryUserById(int id);
//删除用户
public void deleteUser(int id);
//修改用户
public void updateUser(User user);
}
2、DAO接口实现
UserServiceImpl.java类
package com.user.dao.impl;
import java.util.List;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
import com.user.dao.UserDao;
import com.user.model.User;
public class UserDaoImpl extends SqlMapClientDaoSupport implements UserDao{
//添加用户
public void insertUser(User user ){
System.out.println("插入数据User开始--->UserDao"+"---"+user.getUserid()+"-"+user.getUsername()+"-"+user.getPassword());
this.getSqlMapClientTemplate().insert("insertUser",user);
System.out.println("插入数据User结束--->UserDao");
}
//查询用户
public List queryUser(User user){
System.out.println("查询数据User开始--->UserDao"+"---"+user.getUserid()+"-"+user.getUsername()+"-"+user.getPassword());
List userlist=(List)this.getSqlMapClientTemplate().queryForList("queryUser", user);
System.out.println("查询数据User结束--->UserDao");
return userlist;
}
//删除用户
public void deleteUser(int id) {
System.out.println("删除数据User开始--->UserDao"+"---"+id);
this.getSqlMapClientTemplate().delete("deleteUser", id);
System.out.println("删除数据User结束--->UserDao"+"---"+id);
}
//查询用户by id
public User queryUserById(int id) {
System.out.println("查询数据BY ID开始--->UserDao"+"---"+id);
User user=(User)this.getSqlMapClientTemplate().queryForObject("queryUserById", id);
System.out.println("查询数据BY ID结束--->UserDao"+"---"+id);
return user;
}
//修改用户
public void updateUser(User user) {
System.out.println("更新数据User开始--->UserDao"+"---"+user.getUserid());
this.getSqlMapClientTemplate().update("updateUser", user);
System.out.println("更新数据User结束--->UserDao"+"---"+user.getUserid());
}
}
