import com.wjy.test1.service.UserServiceTest1;


@RestController
public class UserController {

    @Autowired
    public UserServiceTest1 userServiceTest1;
    
    @RequestMapping("/insertTest1ByService")
    public String insertTest1ByService(String name,Integer age) {
        userServiceTest1.insertuser1(name, age);
        return "success";
    }
    
    
}

2、service

/ **

 * / 
Package com.wjy.test1.service; 

Import org.springframework.beans.factory.annotation.Autowired;
 Import org.springframework.stereotype.Service;
 Import org.springframework.transaction.annotation.Transactional; 

Import COM .wjy.test1.dao.UserMapperTest1; 

/ **

@Service 
public  class UserServiceTest1 {

     * @Description: If no transaction control then inserted into the database after error where the data will not be rolled back annotate to roll back @Transactional
     */
    @Transactional
    public String insertuser1(String name,Integer age) {

        int i =1/0;
        return "success";
    }

}

3、mapper

/**

package com.wjy.test1.dao;

import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;

import com.wjy.entity.User;

/**

    @Insert("insert into users (name,age) values(#{name},#{age})")
    int insert(@Param("name") String name,@Param("age") Integer age);
}

package com.wjy;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class APP {

    public static void main(String[] args) {
