一般情況下,我們在使用struts2時,都是通過提交form表單,然後提交actionName.do(action).然而我們想在頁面載入時即進行查詢,如何做?

個人實踐如下:

index.jsp頁面

<jsp:forward  page="actionName.do"></jsp:forward> 

main.jsp頁面

就是你要顯示資料的頁面

struts2.xml 配置

<action name="actionName" class="edison.esop.action.ScreenHeaderAction" method="lineNamelist"> 
			<result  name="lineNamelist">/main.jsp</result>
			
			<result name="input">/downFail.jsp</result>
		</action>
 

具體對應的action 類,我就不寫了,只寫對應的方法 

public String lineNamelist() {
......

}
