我是 Spring MVC 3.0 的新手，正在尝试编写一个示例 Web 应用程序来感受它。我能够获取 url 来调用我的关联 Controller ，但无法将请求转发到我的 jsp 资源，如浏览器上的输出所示:
The requested resource (/Spring30HelloWorld/helloworldcontroller) is not available.
如果能就解决问题提出建议，我们将不胜感激!!请引用下面我的代码设置。
提前致谢!

最佳答案
您将您的 servlet 映射到 *.htm
改变
@RequestMapping("/helloWorld" )
与
@RequestMapping("/helloWorld.htm" )
然后输入/A/helloworld.htm
此外，您还可以阅读 Spring MVC 框架 online doc
