使用说明
注解失效问题
@Transactional 应用在非 public 修饰的方法上
@Transactional 注解属性 rollbackFor 设置错误
同一个类中方法调用,导致@Transactional失效
异常被你的 catch“吃了”导致@Transactional失效
数据库引擎不支持事务
开启多线程任务时,事务管理会受到影响
@Service
public class ServiceA {
@Transactional
public void threadMethod(){
this.insert();
System.out.println("main insert is over");
for(int a=0 ;a<3;a++){
ThreadOperation threadOperation= new ThreadOperation();
Thread innerThread = new Thread(threadOperation);
innerThread.start();
}
}
public class ThreadOperation implements Runnable {
public ThreadOperation(){
}
@Override
public void run(){
insert();
System.out.println("thread insert is over");
}
}
public void insert(){
//do insert......
}
}
@Service
public class ServiceA {
@Autowired
private ServiceB serviceB;
@Transactional
public void threadMethod(){
this.insert();
System.out.println("main insert is over");
for(int a=0 ;a<3;a++){
ThreadOperation threadOperation= new ThreadOperation();
Thread innerThread = new Thread(threadOperation);
innerThread.start();
}
}
public class ThreadOperation implements Runnable {
public ThreadOperation(){
}
@Override
