異常原因
本地和遠程的member序列化后的serialVersionUID不
解決方法
將本地的序列化的類中的版本號（serialVersionUID ）改成和遠程中一樣，在本地的序列化類里的private static final long serialVersionUID = 改成遠程的就行了，如果沒有的話就加上這句。
關於“org.hibernate.type.SerializationException: could not deserialize”，我查了很多的資料，大概有以下幾個原因：
1.該類的序列版本號與從流中讀取的類描述符的版本號不匹配（jdk版本更換會造成這個問題）
2.該類包含未知數據類型（hibernate配置文件中未指定數據類型）
3.該類沒有可訪問的無參數構造方法
