spring练习，在Eclipse搭建的Spring开发环境中，使用set注入方式

事务的开启

实现思路&＃xff1a;

在com.mhys.pojo包下&＃xff0c;创建User类。 在com.mhys.dao包下&＃xff0c;创建UserDao类。

package com.mhys.bean;

public class Users {

private String userId;

private String userName;

private String password;

private int age;

private String address;

private String flag;

public Users() {

super();

}

public Users(String userId, String userName, String password, int age, String address, String flag) {

super();

this.userId &＃61; userId;

this.userName &＃61; userName;

this.password &＃61; password;

this.age &＃61; age;

this.address &＃61; address;

this.flag &＃61; flag;

}

&＃64;Override

public String toString() {

return “Users [userId&＃61;” &＃43; userId &＃43; “, userName&＃61;” &＃43; userName &＃43; “, password&＃61;” &＃43; password &＃43; “, age&＃61;” &＃43; age

• “, address&＃61;” &＃43; address &＃43; “, flag&＃61;” &＃43; flag &＃43; “]”;

}

public String getUserId() {

return userId;

}

public void setUserId(String userId) {

this.userId &＃61; userId;

}

public String getUserName() {

return userName;

}

public void setUserName(String userName) {

this.userName &＃61; userName;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password &＃61; password;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age &＃61; age;

}

public String getAddress() {

return address;

}

public void setAddress(String address) {

this.address &＃61; address;

}

public String getFlag() {

return flag;

}

public void setFlag(String flag) {

this.flag &＃61; flag;

}

}

package com.mhys.Dao;

import com.mhys.bean.Users;

public class UsersDao {

public User 《一线大厂Java面试题解析&＃43;后端开发学习笔记&＃43;最新架构讲解视频&＃43;实战项目源码讲义》无偿开源 威信搜索公众号【编程进阶路】 s getUserById(String userId){

Users users &＃61; new Users(“130006”, “杨明金”, “123456”, 20, “云南”, “1”);

return users;

}

public Boolean insertUser(Users users){

System.out.println(“插入数据&＃xff1a;”&＃43;users.getUserId()&＃43;“&＃xff0c;”&＃43;users.getUserName()

&＃43;“&＃xff0c;”&＃43;users.getPassword()&＃43;“&＃xff0c;”&＃43;users.getAge()&＃43;“&＃xff0c;”

&＃43;users.getAddress()&＃43;“&＃xff0c;”&＃43;users.getFlag());

return true;

}

public Boolean updataUserByid(Users users){

System.out.println(“修改用户编号&＃xff1a;”&＃43;users.getUserId()&＃43;“的密码为&＃xff1a;”&＃43;users.getPassword());

return true;

}

public Boolean deleteUserByid(Users users){

System.out.println(“删除用户编号&＃xff1a;”&＃43;users.getUserId()&＃43;“的信息”);

return true;

}

}

在com.mhys.service包下&＃xff0c;创建UserService类。

package com.mhys.Dao;

import com.mhys.bean.Users;

public class UsersService {

private UsersDao usersDao;

public Users getUserInfoById(String userId){

Users users &＃61; usersDao.getUserById(userId);

return users;

}

public Boolean insertUserInfo(Users users) {

System.out.println(“开启事务”);

usersDao.insertUser(users);

System.out.println(“提交事务”);

System.out.println(“关闭事务”);

return true;

}

public Boolean updataInfo(Users users) {

System.out.println(“开启事务”);

usersDao.updataUserByid(users);
