org.springframework.transaction.UnexpectedRollbackException: Transaction rolled back because it has

org.springframework.transaction.UnexpectedRollbackException: Transaction rolled back because it has been marked as rollback-only

原因：spring事务嵌套，内层异常被外层try-catch，外层正常commit，或者内层手动设置回滚
例1：内层事务手动回滚

@Transactional(rollbackFor = Exception.class)
public void insert() {
	userService.m1();
}
    
@Transactional(rollbackFor = Exception.class)
public void m1() {
	//手动设置事务回滚
	TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
}

例2：外层try-catch内层异常

@Transactional(rollbackFor = Exception.class)
public void add() {
	try {//外层进行try-catch
		userService.m2();
	} catch (Exception e) {
		log.error("111",e);
	}
}

@Transactional(rollbackFor = Exception.class)
public void m2() {
	mapper.insert(new User());
	//内层抛出异常
	throw new RuntimeException("aaa");
}

解决方法

• 去掉任意一个方法的事务注解
• 外层try-catch转为对内层的方法try-catch
• 设置不同的propagation
• 手动回滚改抛异常，外层不捕获
