Spring事务嵌套抛异常org.springframework.transaction.UnexpectedRollbackException: Transaction rolled back because it has been marked as rollback-only

在业务接口中，一个方法嵌套了另外一个方法，2个方法上都加了@Transactional事务注解。

业务接口：

@Service
public class TransactionalTestServiceImpl implements TransactionalTestService {

    @Autowired
    private TransactionalTestHandle transactionalTestHandle;

    @Override
    @Transactional
    public void function() throws Exception {
        Pool record = new Pool();
        transactionalTestHandle.executeTask(record);
    }
}

嵌套方法

@Transactional(propagation = Propagation.REQUIRED, rollbackFor = {Exception.class})
    public void executeTask(Pool record) throws ServiceException {

        if (record.getDocvalue() == null || (record.getDocvalue().compareTo(BigDecimal.valueOf(0)) == 0)) {
            throw new ServiceException("单据金额为零忽略此记录");
        }

        AccountCustomer accountCustomer0 = new AccountCustomer();
        accountCustomer0.setEid(11000018);
        accountCustomer0.setCustid(101L);
        accountCustomer0.setCustname("测试1");
        accountCustomerMapper.insertSelective(accountCustomer0);
}

嵌套方法中校验了参数，校验失败抛ServiceException异常。

运行结果：

出现UnexpectedRollbackException异常的原因：

1.嵌套事务方法executeTask声明了任何Exception异常都会回滚，而外层方法function没有显示声明任何回滚异常。

2.ServiceExceptiony异常是直接从Exception继承的。

3.执行executeTask方法抛了ServiceException异常时，会回滚，Spring标记该事务状态为rollback-only，需要回滚事务；而外层方法没有声明任务回滚异常（默认是RuntimeException会回滚）,需要提交事务，嵌套事务需要回滚，而外层事务需要提交，事务提交冲突就抛了上面的异常。

最佳实践：在Spring中，自定义异常从RuntimeException继承，在业务接口中使用自定义异常时，没有特需需求，事务中不需要配置回滚异常；事务嵌套也不会出现UnexpectedRollbackException

Spring中开启了事务的方法，默认对RuntimeException异常进行回滚，而Postgresql驱动包中org.postgresql.util.PSQLException驱动包中的异常是继承Exception，为什么数据库抛出来的异常也会回滚呢？

PSQLException异常继承关系

public class PSQLException extends SQLException {
}

public class SQLException extends java.lang.Exception
                          implements Iterable<Throwable> {
}

原因是Spring对数据库异常做了转换，最终是从RuntimeException继承

else if (Arrays.binarySearch(this.sqlErrorCodes.getDuplicateKeyCodes(), errorCode) >= 0) {
                    logTranslation(task, sql, sqlEx, false);
                    return new DuplicateKeyException(buildMessage(task, sql, sqlEx), sqlEx);
                }


public class DuplicateKeyException extends DataIntegrityViolationException {
}

public class DataIntegrityViolationException extends NonTransientDataAccessException {
}

public abstract class NonTransientDataAccessException extends DataAccessException {
}

public abstract class DataAccessException extends NestedRuntimeException {
}

public abstract class NestedRuntimeException extends RuntimeException {
}
