这篇文章主要介绍了springboot使用事物注解方式代码实例,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考
1.在启动类Application中添加注解@EnableTransactionManagement
import tk.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.transaction.annotation.EnableTransactionManagement;
@SpringBootApplication
@EnableTransactionManagement //开启书屋管理注解模式 最新的版本可以省略
@MapperScan("com.xz.springboot.mapper") //扫描该包下所有的接口并为该接口生成实现类
public class Springboot01Application {
public static void main(String[] args) {
SpringApplication.run(Springboot01Application.class, args);
}
}
2.在业务层添加@Transactional
import com.xz.springboot.bean.User;
import com.xz.springboot.mapper.UserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
@Service
public class UserService {
@Autowired
private UserMapper userMapper;
public List<User> queryAll(){
System.out.println("热部署");
return userMapper.findAll();
}
@Transactional
public void deleteById(Integer id) {
userMapper.deleteById(id);
// int c=10/0;
}
}
