我正在開發一個帶有Jersey和Hibernate的小型REST Web服務器。一路上,我遇到了代表Hibernate的奇怪行爲。也就是說,在curl的POST請求之後嘗試Session.save()時,服務器會回覆500,但在命令窗口中看不到任何錯誤。HIbernate不會拋出異常或顯示錯誤
但是,當我切換一個斷點,並執行光標的一個步驟運行在依賴關係中的一些罐子裏,我最終追蹤錯誤信息。它仍然沒有顯示在任何地方。
如何強制hibernate顯示所有這些錯誤?還是需要設置澤西島?
,我切換斷點的方法:
@POST
@Path("{id}/comments/new")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response handlePostNewComment(@PathParam("id") int taskId, ItemComment newComment) {
newComment.setItemId(taskId);
Session s = HibernateUtil.getSessionFactory().openSession();
Transaction tx = s.beginTransaction();
**Integer newCommentId = (Integer)s.save(newComment);**
s.flush();
tx.commit();
s.close();
HashMap res = new HashMap();
res.put("id", newCommentId);
return Response.status(201).entity(res).build();
}
服務器響應捲曲:
$捲曲-i -X POST -H 「內容類型:應用程序/ JSON」 - data @ comm.json localhost:8000/task/19/comments/new

對於成功的請求,它看起來是一樣的,除了一些從休眠狀態回顯的SQL。
調試時我終於在org.glassfish.jersey.server.model.internal.AbstractJavaResourceMethodDispatcher類
java.lang.ClassCastException遇到異常的地方:java.lang.Long中不能轉換爲java.lang.Integer
這發生了好幾次,有不同的錯誤信息。
如何強制這些組件向stdout或stderr顯示錯誤消息?或者將它們記錄在某處?
這解決了這個問題。非常感謝,對於遲到的確認感到抱歉。你知道這是否是記錄在澤西島的行爲,即他們說服務器代碼不會拋出異常的代碼調用它(我自己的)? – cristianmtr
