java - Liferay 错误 [RuntimePageImpl-16] 不是有效的包含

Question

我正在努力使用 doView() 方法并初始化 portlet.xml 中的参数。到目前为止，我一直在尝试的是，当我单击按钮或链接时重定向到另一个 View 。为此，我创建了两个 JSP:

View .jsp vista2.jsp

我在 portlet.xml 中定义它们:

<portlet>
    <portlet-name>res-prot</portlet-name>
    <display-name>Res Prot</display-name>
    <portlet-class>com.test.ResProt</portlet-class>
    <init-param>
        <name>view-jsp</name>
        <value>html/resprot/view.jsp</value>
    </init-param>
    <init-param>
        <name>vista2-jsp</name>
        <value>/vista2.jsp</value>
    </init-param>   
    (...)

然后，我在 init() 方法中初始化它们:

String viewJSP;
String vista2JSP;

public void init() throws PortletException {
    viewJSP = getInitParameter("view-jsp");
    vista2JSP = getInitParameter("vista2-jsp");
}

最后，我调用 doView() 方法，如果参数“navegacion”为空，该方法将调用 viewJSP:

@Override
    public void doView(RenderRequest renderRequest, RenderResponse renderResponse) throws IOException, PortletException {
        String destino = viewJSP;

        try {
            // we redirect only if "navegacion" is sent from the jsp
            if (renderRequest.getParameter("navegacion") != null){
                if(renderRequest.getParameter("navegacion").equalsIgnoreCase("vista2JSP")){
                    destino = vista2JSP;
                }
            }
            System.out.println("DESTINO: "+destino);
            include(destino, renderRequest, renderResponse);
        } catch (Exception e) {
            e.printStackTrace();

        }
    }

然后，在 vista2.jsp 中，我只使用 renderURL 来执行该调用，但我什至没有到达那里。我收到此错误并且 portlet 显示为空:

09:21:41,402 ERROR [RuntimePageImpl-16][MVCPortlet:357] html/resprot/view.jsp is not a valid include

这就是这个脏项目的组织方式(请记住，这仅用于测试目的):

这里出了什么问题？

编辑:

如果我以“/”开始路线，它会抛出一个不同的错误:

编辑2:如果我将“view.jsp”移动到根文件夹，则会继续抛出相同的错误:

Answer 1

你应该更换

<value>html/resprot/view.jsp</value>

由

<value>/html/resprot/view.jsp</value>
