我正在使用带注解控制器的SpringMVC 3。我成功地将我的URL（“/HelloWorld）Map到一个控制器并定义了它的GET处理方法。
错误是在键入(App)/HelloWorld URL时，我的Web服务器（GlassFish）给出以下错误：
请求的资源不可用。
但是在GlassFish日志中，我看到URL被挂载。
Map"{[/HelloWorld],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}"ontopublic org.springframework.web.servlet.ModelAndView controllers.HelloWorldController.processHelloWorld()
我的文件：
(1) HelloWorldController.java
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package controllers;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
/**
*
* @author */
@Controller
@RequestMapping("/HelloWorld")
public class HelloWorldController {
@RequestMapping(method = RequestMethod.GET)
public ModelAndView processHelloWorld()
{
ModelAndView model = new ModelAndView("HelloWorldPage");
model.addObject("msg", "Expanded string - hello world");
return model;
}
}(2)Dispatcher-Servlet.xml。注意MVC-Annotation-Driven方法。未使用indexController。

Most controllers will use the ControllerClassNameHandlerMapping above, but
for the index controller we are using ParameterizableViewController, so we must
define an explicit mapping for it.

</html>为什么没有找到URL“/HelloWorld”？

问题解决了。我不得不调用URL“/HelloWorld.htm”以使Map工作。
(The Dispatcher-Servlet在web.xml中的Map是“*.htm”。）谢谢
