我正在扩展JSTL视图类以实现我自己的视图解析器。但是,我遇到了问题。看看我的代码:
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,控件永远不会出现在 setUrl 方法中。因此,内部RequestDispatcher中的url始终为null。
请帮我解决这个问题。

别忘了将TestView放在“myServletName”-servlet.xml
中<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="test.TestView"/>
....
