使用SpringBoot注解方式处理事务回滚实现

2023-07-18 22:02:04 65

我们在SpringBoot和MyBatis整合的时候，需要在SpringBoot中通过注解方式配置事务回滚

1Pojo类

packagecom.zxf.domain;

importjava.util.Date;

publicclassUser{
privateIntegerid;
privateStringname;
privateStringpwd;
privateStringhead_img;
privateStringphone;
privateDatecreate_time;

publicIntegergetId(){
returnid;
}

publicvoidsetId(Integerid){
this.id=id;
}

publicStringgetName(){
returnname;
}

publicvoidsetName(Stringname){
this.name=name;
}

publicStringgetPwd(){
returnpwd;
}

publicvoidsetPwd(Stringpwd){
this.pwd=pwd;
}

publicStringgetHead_img(){
returnhead_img;
}

publicvoidsetHead_img(Stringhead_img){
this.head_img=head_img;
}

publicStringgetPhone(){
returnphone;
}

publicvoidsetPhone(Stringphone){
this.phone=phone;
}

publicDategetCreate_time(){
returncreate_time;
}

publicvoidsetCreate_time(Datecreate_time){
this.create_time=create_time;
}
}

2Mapper接口

我们这里使用注解的方式编写SQL语句

packagecom.zxf.mapper;

importcom.zxf.domain.User;
importorg.apache.ibatis.annotations.Insert;
importorg.springframework.stereotype.Repository;

@Repository
publicinterfaceUserMapper{
@Insert("insertintouser(name,pwd,head_img,phone,create_time)values(#{name},#{pwd},#{head_img},#{phone},#{create_time})")
publicintsave(Useruser);
}

3Service接口和实现类

packagecom.zxf.service;

importcom.zxf.domain.User;


publicinterfaceUserService{
publicintsave(Useruser);
}

packagecom.zxf.service.impl;
importcom.zxf.domain.User;
importcom.zxf.mapper.UserMapper;
importcom.zxf.service.UserService;
importorg.springframework.beans.factory.annotation.Autowired;
importorg.springframework.stereotype.Service;
importorg.springframework.transaction.annotation.Transactional;

@Service
@Transactional//实现事务的时候要在业务类中加入该注解
publicclassUserServiceImplimplementsUserService{
@Autowired
privateUserMapperuserMapper;

@Override
publicintsave(Useruser){
intf=userMapper.save(user);
//intx=5/0;
returnf;
}
}

4Controller层

packagecom.zxf.controller;

importcom.zxf.domain.User;
importcom.zxf.service.UserService;
importorg.springframework.beans.factory.annotation.Autowired;
importorg.springframework.web.bind.annotation.RequestMapping;
importorg.springframework.web.bind.annotation.RestController;
importjava.util.Date;
@RestController
@RequestMapping("api/v1/user")
publicclassUserController{
@Autowired
privateUserServiceuserService;
@RequestMapping("save")
publicObjectsave(){
Useruser=newUser();
user.setName("zhang3");
user.setPwd("abc123");
user.setCreate_time(newDate());
user.setPhone("1789238734");
user.setHead_img("aabbddd.jpg");
userService.save(user);
returnuser;
}
}

5application.properits配置文件

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/online
spring.datasource.username=root
spring.datasource.password=******
mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

6pom文件



4.0.0

org.springframework.boot
spring-boot-starter-parent
2.3.2.RELEASE


com.zxf
xf_spring2
0.0.1-SNAPSHOT
xf_spring2

1.8



org.springframework.boot
spring-boot-starter-web


org.mybatis.spring.boot
mybatis-spring-boot-starter
2.1.2


mysql
mysql-connector-java
5.1.13


org.springframework.boot
spring-boot-starter-test
test


org.junit.vintage
junit-vintage-engine








org.springframework.boot
spring-boot-maven-plugin

6SpringBoot启动类

packagecom.zxf;
importorg.mybatis.spring.annotation.MapperScan;
importorg.springframework.boot.SpringApplication;
importorg.springframework.boot.autoconfigure.SpringBootApplication;
importorg.springframework.transaction.annotation.EnableTransactionManagement;
@SpringBootApplication
@MapperScan("com.zxf.mapper")//扫描mapper接口
@EnableTransactionManagement//事务处理的时候启动类必须要加的注解
publicclassXfSpring2Application{
publicstaticvoidmain(String[]args){
SpringApplication.run(XfSpring2Application.class,args);
}
}

7也是最重要，也是很多人忽视的地方，就是MySQL要支持事务处理才可以

这里一定要记住；否则你的SpringBoot的事务没有任何效果
