参数“方法"为“参数".不起作用(Struts 1) [英] Parameter "method" not working (Struts 1)

问题描述

我在struts.xml中声明了以下操作:

I have the following action declared in my struts.xml:

    <action path="/updateAccountInfo"
            type="org.myCompany.UpdateAccountAction"
            name="myAccountForm"
            scope="session"
            validate="true"
            parameter="method" 
            input="/updateAccountInfo.jsp">
        <forward name="success" path="/updateAccountInfo.jsp" />
    </action>

在我的JSP页面中，我具有以下形式:

In my JSP page, I have the following form:

<html:form action="/updateAccountInfo.do">
    <input type="hidden" name="method" value="sendMessage" />

在我的java类中，我具有以下方法:

In my java class, I have the following method:

public final ActionForward sendMessage(final ActionMapping mapping, final ActionForm form, final HttpServletRequest request, final HttpServletResponse response) throws Exception {
    System.out.println("sending");
    return null;
}

Struts代替运行sendMessage，而是调用execute方法.为什么?我的struts-config错误吗?还是我缺少其他配置设置?

Instead of running sendMessage, Struts call the execute method. Why? Is my struts-config wrong? Or am I missing another config setting?

推荐答案

请首先确保您的操作扩展了DispatchAction.您可能不应覆盖该类中的execute方法，因为该方法负责提取请求参数并调用相应的方法.如果您覆盖执行，则该逻辑将不再执行.

Please first make sure that your action extends DispatchAction. You probably should not override the execute method in that class since that method is responsible for extracting the request parameter and invoking the corresponding method. If you override execute this logic will no longer execute.
