Transaction rolled back because it has been marked as rollback-only异常产生的原因

文档

1. Spring事务传播行为的七种类型
2. Transaction rolled back because it has been marked as rollback-only异常产生的原因

产生原因

在Spring事务传播行为中，如果当前存在事务，PROPAGATION_REQUIRED、PROPAGATION_SUPPORTS、PROPAGATION_MANDATORY这三种事务传播类型会加入到当前事务，加入到当前事务表示：与当前事务同时提交或回滚

如果内层方法抛出异常，整体事务就会被标记为回滚，但是如果此时外层方法捕获内层方法抛出的异常，外层方法又无其它异常，外层方法则会继续执行到结束。此时仍然会做回滚操作，并且会抛出异常：org.springframework.transaction.UnexpectedRollbackException: Transaction rolled back because it has been marked as rollback-only

场景复现

PropagationServiceAImpl.java类的requiredToRequired1方法，事务传播类型为REQUIRED

PropagationServiceBImpl.java类的required方法，事务传播类型为REQUIRED

required方法存在异常

requiredToRequired1调用required方法，并捕获异常，此外，requiredToRequired1无其它异常

• PropagationServiceAImpl.java

  @Override
  @Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
  public void requiredToRequired1() {update1();try {propagationServiceB.required();} catch (Exception e) {e.printStackTrace();}
  }
  

• PropagationServiceBImpl.java

  @Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
  public void required() {update3();int i = 1 / 0;
  }
  

• 此时，update1、update3均会回滚，并且会抛出org.springframework.transaction.UnexpectedRollbackException: Transaction rolled back because it has been marked as rollback-only异常

• 如果PropagationServiceAImpl.java类的requiredToRequired1方法有其它的异常抛出，将不会产生上述异常

如有错误，欢迎指正！
