环境
eclipse 4.7
jdk 1.8
Spring Boot 1.5.2
一、springboot整合事务
事务分类:编程事务、声明事务(XML、注解),推荐使用注解方式,springboot默认集成事物,只主要在方法上加上@Transactional即可
1、controller
package com.wjy.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; 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; /** * @Desc * @author wangjy15 */ @Service public class UserServiceTest1 { @Autowired private UserMapperTest1 userMapperTest1; /** * @Description: 如果没有事务控制 那么报错之后 插入到库里的数据不会回滚 加上 注解@Transactional 就可以回滚 */ @Transactional public String insertuser1(String name,Integer age) { userMapperTest1.insert(name, age); int i =1/0; return "success"; } }
3、mapper
/** * */ package com.wjy.test1.dao; import org.apache.ibatis.annotations.Insert; import org.apache.ibatis.annotations.Param; import org.apache.ibatis.annotations.Select; import com.wjy.entity.User; /** * @Desc * @author wangjy15 */ public interface UserMapperTest1 { @Select("SELECT * FROM users WHERE NAME = #{name}") User findByName(@Param("name") String name); @Insert("insert into users (name,age) values(#{name},#{age})") int insert(@Param("name") String name,@Param("age") Integer age); }
4、APP
package com.wjy; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class APP { public static void main(String[] args) { SpringApplication.run(APP.class, args); } }
5、测试验证
http://localhost:8080/insertTest1ByService?name=wangsan0010&age=1000
二、SpringBoot分布式事务管理
传统项目:jta+automatic
