spring - 扩展 JSTL 视图类

Question

我正在扩展 JSTL 视图类来实现我自己的视图解析器。但是，我遇到了问题。查看我的代码：

public class TestView extends JstlView {
    private String fo_suffix = "_jo";

    public void setUrl(String url)
    {
        //We need to change the inputed url to add a prefix for fo
        super.setUrl(url.replace("\\.jsp", fo_suffix+ ".jsp"));
    }
    public void render(Map<String, ?> model, HttpServletRequest request,
            HttpServletResponse response) throws Exception {
        final StringWriter xmlfo = new StringWriter();

        HttpServletResponseWrapper wrapper = new HttpServletResponseWrapper(
                response) {
            @Override
            public PrintWriter getWriter() throws IOException {
                return new PrintWriter(xmlfo);
            }
        };



        super.render(model, request, wrapper);

在上面的代码中，当我调试时，控件永远不会到达setUrl方法。所以内部 RequestDispatcher 中的 url 始终为空。

请帮我解决问题。

不要忘记将 TestView 放入“myServletName”-servlet.xml

<bean id="viewResolver"    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="test.TestView"/>
....
