仅标记为回滚的事务:如何查找原因

hibernate

我在@Transactional方法中提交事务时遇到问题:

methodA() {
    methodB()
}

@Transactional
methodB() {
    ...
    em.persist();
    ...
    em.flush();
    log("OK");
}

当我从methodA()调用methodB()时,该方法成功通过,并且可以在日志中看到“确定”。但后来我明白了

Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Transaction marked as rollbackOnly org.springframework.transaction.TransactionSystemException: Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Transaction marked as rollbackOnly
    at org.springframework.orm.jpa.JpaTransactionManager.doCommit(JpaTransactionManager.java:521)
    at org.springframework.transaction.support.AbstractPlatformTransactionManager.processCommit(AbstractPlatformTransactionManager.java:754)
    at org.springframework.transaction.support.AbstractPlatformTransactionManager.commit(AbstractPlatformTransactionManager.java:723)

    at org.springframework.aop.framework.Cglib2AopProxy$DynamicAdvisedInterceptor.intercept(Cglib2AopProxy.java:622)
    at methodA()...
  1. 在异常中完全缺少methodB的上下文-我想这可以吗?
  2. methodB()中的某些内容将事务标记为仅回滚?我如何找到它?例如,是否有一种检查类似getCurrentTransaction().isRollbackOnly()?方法的方法-这样,我可以逐步检查方法并找到原因。

我终于明白了这个问题:

methodA() {
    methodB()
}

@Transactional(noRollbackFor = Exception.class)
methodB() {
    ...
    try {
        methodC()
    } catch (...) {...}
    log("OK");
}

@Transactional
methodC() {
    throw new ...();
}

发生的事情是,即使methodB具有正确的注释,methodC也没有。抛出异常后,第二个异常@Transactional将第一个事务标记为仅回滚。
