我有一个Rest API调用此方法
void Somemethod(){
EntityTransaction entityTransaction = null;
EntityManager entityManager = null;
try {
entityManager = TXNMGMT.getEntityManager();
entityTransaction = entityManager.getTransaction();
entityTransaction.begin()
// Does Something
if (entityTransaction.isActive()) {
entityTransaction.commit();
}
} catch (Throwable throwable){
throwable.printStackTrace();
if (entityTransaction != null) {
try {
entityTransaction.rollback();
} catch (Throwable throwable1){
throwable1.printStackTrace();
throw new UnkownBatchSaveException();
}
}
throw new UnkownBatchSaveException();
}
finally {
if(entityManager != null && entityManager.isOpen()) {
entityManager.close();
}
}
我知道这是UGLY
catch (Throwable throwable){
throwable.printStackTrace();
if (entityTransaction != null) {
try {
entityTransaction.rollback();
} catch (Throwable throwable1){
throwable1.printStackTrace();
throw new UnkownBatchSaveException();
}
}
throw new UnkownBatchSaveException();
}
然后我收到了这个错误

但在这种情况下，我永远不会得到UnkownBatchSaveException();并且调用API只能获得200＆amp;它假定申请成功了
为什么我在回滚时无法抛出UnkownBatchSaveException();？
