iReport的情況在變

我寫這篇文章的代碼在一個變量在iReport的iReport的情況在變

$F{wbsWbkRef.wbkStdRef.stdBlRtntp.blCode} != null ? 
ReportUtil.getFirstEntity($P{JPA_ENTITY_MANAGER}, 
"SELECT "+ 
"CASE WHEN std.stdBlRtntp.blCode IN ('UNIVGRANT' , 'BEHYAR','TEACHER','GRANTED','EXTGRANTED','EXTGRANTED') THEN "+ 
"DECODE (std.stdBlAcctp.blCode , 'UNIVGRANT' ,'داخل','BEHYAR','داخل','TEACHER','داخل','GRANTED','داخل','EXTGRANTED','خارج','EXTGRANTED','ترددي','غير بورس')  "+ 
"END AS SCHOLARSHIPTITLE "+ 
"FROM Student std "+ 
"WHERE std.stdId=:stdId ", 
"stdId="+ $F{wbsWbkRef.wbkStdRef.stdId}, 
"stdId=java.math.BigDecimal") 
: null

，但我得到這個錯誤

沒有錯的Java代碼本身，但它不是一個好的做法以及。問題是Hibernate正在接收的實體名稱，該實體的類路徑或實體到表的映射。

開始通過檢查這個參數的值，$P{JPA_ENTITY_MANAGER}

接下來的時間，我會建議把業務邏輯+在後端，並處理報告介紹，只需把它做好準備的參數。這將在稍後維護或修改報告時幫助您很多。
