## Transaction rolled back because it has been marked as rollback-only ##

spring 具备多种事务传播机制，最常用的是REQUIRED，即如果不存在事务，则新建一个事务；如果存在事务，则加入现存的事务中。  
示例代码如下：

public void A() {
        querySomething(...)；
        try {
          B()
        } catch () {
        }
        saveSomethinf()；
    }
    
    public void B() {
        throw Exception()
    }

此时B会和A存在一个事务中。如果B抛出异常没有捕获，即使在A中捕获并处理，仍会发生异常：**Transaction rolled back because it has been marked as rollback-only**  
因为spring会在A捕获异常之前提前捕获到异常，并将当前事务设置为**rollback-only**，而A觉得对异常进行了捕获，它仍然继续commit，当TransactionManager发现状态为设置为rollback-only时，  
则会抛出UnexpectedRollbackException  
相关代码在AbstractPlatformTransactonManager.java中：

public final void commit(TransactionStatus status) throws TransactionException {
            if (status.isCompleted()) {
                throw new IllegalTransactionStateException(
                        "Transaction is already completed - do not call commit or rollback more than once per transaction");
            }
    
            DefaultTransactionStatus defStatus = (DefaultTransactionStatus) status;
            if (defStatus.isLocalRollbackOnly()) {
                if (defStatus.isDebug()) {
                    logger.debug("Transactional code has requested rollback");
                }
                processRollback(defStatus);
                return;
            }
            if (!shouldCommitOnGlobalRollbackOnly() && defStatus.isGlobalRollbackOnly()) {
                if (defStatus.isDebug()) {
                    logger.debug("Global transaction is marked as rollback-only but transactional code requested commit");
                }
                processRollback(defStatus);
                // Throw UnexpectedRollbackException only at outermost transaction boundary
                // or if explicitly asked to.
                if (status.isNewTransaction() || isFailEarlyOnGlobalRollbackOnly()) {
                    throw new UnexpectedRollbackException(
                            "Transaction rolled back because it has been marked as rollback-only");
                }
                return;
            }
    
            processCommit(defStatus);
        }

**解决方法：**  
在抛出异常的最原始地方处理异常，即在spring捕获到异常之前处理掉
