私はHibernateとSpringには新しく、今ではプロジェクトを開発していたので、なぜこのcatchブロックを試しても理解できませんワーキング。次のようにJavaで例外がtry catchのIDで処理されないtryブロックにif elseがあります
プロジェクト構造は次のとおりです。 JSP>コントローラ>サービス>ダオ
私は次のようにデータベースの更新を行うための売り手コントローラに渡されることで必要なフィールド、とビーンという名前の売り手を持っています。
@RequestMapping(value = "/updateSeller")
public String updateSellerProfile(Model model, HttpSession session, SellerFormBean seller) {
int action = seller.getAction();
try {
if (action == 1 || action == 2) {
//this modify seller Profile is giving an Exception of DataIntegrityViolationException: not-null property references a null or transient value
seller = sellerService.modifySellerProfile(seller);
model.addAttribute("countries", commonService.getCountryDropdown());
}
if (action == 3 || action == 4) {
sellerService.modifyCaseStudies(seller.getSellerId(), seller.getCaseStudies());
}
Integer sellerId = (Integer) session.getAttribute("entityId");
SellerFormBean bean=null;
bean = sellerService.retrieveSeller(sellerId);
Long userId = (Long) session.getAttribute("userId");
try {
UserFormBean user = userService.getUser(userId);
bean.setUser(user);
} catch (IllegalAccessException | InvocationTargetException e) {
log.error("sellerController - updateSeller , getUser Failed ",e);
}
model.addAttribute("seller", bean);
model.addAttribute("message", "Profile updated successfully");
}catch(IllegalStateException e){
log.error("sellerController - updateSeller : ",e);
} catch (NullPointerException |HibernateException e) {
log.error("sellerController - updateSeller",e);
model.addAttribute("error",
"Error occured while updating the profile. Please try again later. If the problem persist, then please conctact system administrator");
}catch(Exception e) {
log.error("sellerController - updateSeller",e);
model.addAttribute("error",
"Error occured while updating the profile. Please try again later. If the problem persist, then please conctact system administrator");
}
return selectTab(action);
}
今私はどこで、どのようにその誤りを訂正するためにエラーがあるが、例外は、コントローラのトライカテーテル検査ブロック内でキャッチされていませんmodifySellerProfile方法で提起された例外がある場合に問題があることを知っています。理由は何でしょうか？
しかし、私はコントローラにこのようなものを使用するときに例外が処理されます。
try {
//this modify seller Profile is giving an Exception of DataIntegrityViolationException: not-null property references a null or transient value
seller = sellerService.modifySellerProfile(seller);
}catch (Exception e) {
log.error("Hello My Error I caught you",e);
}
次のようにmodifySellerProfileがある：
public void modifySellerProfile(Seller instance){
log.debug("attaching dirty Seller instance");
Seller sellerDo = new Seller();
BeanUtils.copyProperties(formBean, sellerDo, "caseStudies", "references", "accelerators");
///====Deliberately created an exception for testing
instance.setCompanyType(null);
sessionFactory.getCurrentSession().saveOrUpdate(instance);
log.debug("attach successful");
}

消滅しない、それはしようと '最も近くでキャッチされますスタックトレース – Jens
に例外を追加してください：
SessionFactoryUtilsのコードのこの部分のような何かを行うため です'それが' catch 'または' throw 'で再び定義されているかどうかを管理します。あなたは 'catch（Exception e）'を持っているので、すべての例外を捕捉しますが、 'Error'は捕捉しません。スタックトレースを追加して確認します。 – AxelH
'Throwable'は実際の基本クラスであり、チェックされた' Exception'からのものです。 'DataIntegrityViolationException'は例外を拡張していないかもしれませんが、別のブランチであるRuntimeExceptionをいくつか拡張しているかもしれません。ええ、少し矛盾した名前です。 Throwableをキャッチしてみてください。 –
