未能延遲初始化集合沒有會話或會話已關閉

Question

當我填寫屬性date_declined的值時，我在無關屬性上得到以下錯誤。

Application Execution Exception 
Error Type: org.hibernate.LazyInitializationException : [N/A] 
Error Messages: failed to lazily initialize a collection of role: blm_doc.blm_doc_cases, no session or session was closed 

Answer 1

該屬性定義中缺少ormtype = date。

property name="declined_date" 
    column="DECLINED_DATE" 
    sqltype="DATE" 
    ormtype="date";
