參數“registrationId”的類型應為“整數”，而不是“java.lang.Long”

Question

我已經在我的 tomcat 服務器上從BIRT 3.7.1升級到BIRT 4.4.2並且它可以很好地處理我的舊報告，這些報告具有非整數數據類型的參數。 當我運行要求數據類型為整數的參數的報告時，它會引發以下錯誤。 我已在BIRT報告中將該參數聲明為整數，但我的舊版本BIRT沒有任何問題。 為什么這個參數問題會出現在新的問題中，我該如何解決這個問題

Answer 1

最后我得到了解決方案。 舊的 BIRT 版本在 BIRT 報告引擎 jar 中存在的EngineTask.java不使用此類型檢查，但新版本使用。 這就是ParameterValidationException發生的原因。 因此，在您的項目源代碼中找出您的Servlet java 類，該類將參數值設置為 Long 或任何其他值。 將其更改為int或您在報告中選擇的數據類型。 您可以通過搜索PDFRenderOption() 、 EXCELRenderOption() 、 HTMLRenderOption()等輕松找到您的Servlet java 類。 Servlet 類通常包含這些 Render 選項。
