你好朋友我正在遵循Spring + Hibernate + JPA。 我正在嘗試在我的數據庫上執行刪除操作。通過一個對象刪除作爲參數不工作
當我通過從控制器和Tha模型的對象做如下這是不工作
@Transactional(readOnly = false)
@Override
public void doDeleteCategory(Category deleteCategory) {
try {
entityManager.remove(deleteCategory);
} catch (Exception exc) {
logger.info(exc.getStackTrace().toString());
}
}
但是，當我再次獲得相同的對象不是它的工作原理如下
@Transactional(readOnly = false)
@Override
public void doDeleteCategory(Category deleteCategory) {
Category category = retrieveCategory(deleteCategory.getCategoryId());
try {
entityManager.remove(deleteCategory);
} catch (Exception exc) {
logger.info(exc.getStackTrace().toString());
}
}
我好奇地知道爲什麼它發生，而創建和更新/合併工作完美時，我做了兩種方法相同。
這裏是棧跟蹤：

可能它是分離的，那很好捕捉異常說什麼？ – gadget
@gadget事務回滾... –
我敢打賭，你傳遞的是從你的控制器分離的實體，但爲了確保我需要看到完整的堆棧跟蹤...必須有一個原因，該堆棧跟蹤的某個地方trx回滾 – gadget
