GWT GiLead休眠IllegalArgumentException異常嘗試發送LightEntity throw wire

Question

在我的GWT客戶端，我從服務器端請求一個LightEntities列表。我對這些實體進行了一些修改，並且嘗試將它們發回以進行保存。

當我做RPC調用失敗但下列情況除外：

我坐在這個錯誤小時了，這就是LazyKiller是殺了我，我應該在哪裏再看任何提示？

Answer 1

我試圖用基列，但它是不好：

1. 它是如此的侵入;
2. 它很難配置。

我寫了一個小型的類，它將hibernate代理轉換爲普通的java類，它確實幫助了我。 它作爲開源共享那裏，所以你可以嘗試：

Answer 2

我無法解決這個問題，但我做了一個小小的解決方法： 我在客戶端克隆我的實體，然後我可以將它們發回服務器端。
