Struts2不顯示字符串屬性

Question

我對Struts 2相當熟悉...自3天以來，我一直陷入一個非常奇怪的問題。
我的動作課有很多屬性； 一些是整數，其他是字符串。
我知道我已經為我的所有屬性創建了兩個getter / setter方法
展示擴展了struts-default和json-default，因為我需要使用struts2-jquery gridtag ...來渲染json表的類。
我的所有屬性均未打印過sord，sdix，page ..標記定義的那些屬性

頁面的值已顯示，但myeditOptions的值未顯示..... Pleeeease幫助

Answer 1

@ Lord-zed我看到您僅在prepare（）方法上填充myEditOptions。 當單擊“執行”操作時，不會再次填充它。 因此，要么必須再次在execute（）中填充它，要么在prepare操作的jsp中放置一個隱藏字段，以將其發布回“ execute”操作。 我建議在execute（）中重新填充它。

Answer 2

無需強制轉換getter和setter，您也應該創建不同的getter和setters文件以及DAO。
