使用SpringBoot注解方式处理事务回滚实现

发布日期： 2026-01-12 阅读量： 作者： 用户投稿

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

1 Pojo类

package com.zxf.domain;

import java.util.Date;

public class User {
  private Integer id;
  private String name;
  private String pwd;
  private String head_img;
  private String phone;
  private Date create_time;

  public Integer getId() {
    return id;
  }

  public void setId(Integer id) {
    this.id = id;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public String getPwd() {
    return pwd;
  }

  public void setPwd(String pwd) {
    this.pwd = pwd;
  }

  public String getHead_img() {
    return head_img;
  }

  public void setHead_img(String head_img) {
    this.head_img = head_img;
  }

  public String getPhone() {
    return phone;
  }

  public void setPhone(String phone) {
    this.phone = phone;
  }

  public Date getCreate_time() {
    return create_time;
  }

  public void setCreate_time(Date create_time) {
    this.create_time = create_time;
  }
}

2 Mapper接口

我们这里使用注解的方式编写SQL语句

package com.zxf.mapper;

import com.zxf.domain.User;
import org.apache.ibatis.annotations.Insert;
import org.springframework.stereotype.Repository;

@Repository
public interface UserMapper {
  @Insert("insert into user (name,pwd,head_img,phone,create_time) values(#{name},#{pwd},#{head_img},#{phone},#{create_time})")
    public int save(User user);
}

3 Service接口和实现类

package com.zxf.service;

import com.zxf.domain.User;


public interface UserService {
  public int save(User user);
}

package com.zxf.service.impl;
import com.zxf.domain.User;
import com.zxf.mapper.UserMapper;
import com.zxf.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service
@Transactional //实现事务的时候要在业务类中加入该注解
public class UserServiceImpl implements UserService {
  @Autowired
  private UserMapper userMapper;

  @Override
  public int save(User user) {
    int f= userMapper.save(user);
   // int x=5/0;
    return f;
  }
}

4 Controller层

package com.zxf.controller;

import com.zxf.domain.User;
import com.zxf.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.Date;
@RestController
@RequestMapping("api/v1/user")
public class UserController {
  @Autowired
  private UserService userService;
   @RequestMapping("save")
  public Object save(){
    User user=new User();
      user.setName("zhang3");
      user.setPwd("abc123");
      user.setCreate_time(new Date());
      user.setPhone("1789238734");
      user.setHead_img("aabbddd.jpg");
    userService.save(user);
    return user;
  }
}

5 application.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

6 pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

      </exclusions>
    </dependency>
  </dependencies>

  <build>
    <plugins>

        <artifactId>spring-boot-maven-plugin</artifactId>

    </plugins>
  </build>
</project>

6 SpringBoot启动类

package com.zxf;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.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
public class XfSpring2Application {
  public static void main(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
