Question

我正在努力使用doView（）方法并从portlet.xml初始化参数。到目前为止，我一直在尝试的是，当我点击按钮或链接时，只需重定向到另一个视图。为此，我创建了两个JSP：

view.jsp的 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，该方法调用viewJSP，如果参数＆＃34; navegacion＆＃34;是空的：

@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来做那个调用，但我甚至都没有到达那里。我收到此错误，portlet显示为空：

09：21：41,402 ERROR [RuntimePageImpl-16] [MVCPortlet：357] html / resprot / view.jsp不是有效的包含

这就是这个脏项目的组织方式（请记住，这仅用于测试目的）：

这里失败了什么？

编辑：

如果我按＆＃34; /＆＃34;开始路线，则会引发不同的错误：

编辑2：如果我移动＆＃34; view.jsp＆＃34;到根文件夹，不断抛出相同的错误：

你应该替换

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

通过

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