Spring 3 MVC Nesting RequestMapping
提问by Ph??ng Nguy?n
From Spring Official Document, Spring 3 MVC look to be support nesting Request Mapping. http://static.springsource.org/spring/docs/3.0.0.RELEASE/spring-framework-reference/pdf/spring-framework-reference.pdfIn page 448, they mentioned:
从 Spring 官方文档来看，Spring 3 MVC 看起来是支持嵌套请求映射的。 http://static.springsource.org/spring/docs/3.0.0.RELEASE/spring-framework-reference/pdf/spring-framework-reference.pdf在第 448 页中，他们提到：
@Controller
@RequestMapping("/appointments")
public class AppointmentsController {
//...
@RequestMapping(value="/new", method = RequestMethod.GET)
public AppointmentForm getNewForm() {
return new AppointmentForm();
}
//...
}
(I have eliminated some code for readability)
In such case, they claimed that a request to /appoinments/newwill invoke the getNewFormmethod.
However, it doesn't work with my local Google App Engine server (though GAE server works just fine with mapping that are not nested).
I create an example controller like below:
（为了可读性，我删除了一些代码）在这种情况下，他们声称请求/appoinments/new将调用该getNewForm方法。但是，它不适用于我的本地 Google App Engine 服务器（尽管 GAE 服务器适用于非嵌套映射）。我创建了一个示例控制器，如下所示：
@Controller
@RequestMapping("/basic.do")
public class HelloWorldController {
@RequestMapping(value="/hello", method=RequestMethod.GET)
public ModelAndView helloWorld() {
ModelAndView mav = new ModelAndView();
mav.setViewName("basic/helloWorld");
mav.addObject("message", "Hello World From Phuong!");
return mav;
}
}
but a request to /basic.do/helloalways results in 404 error.
但是请求/basic.do/hello总是导致 404 错误。
Wonder if anything wrong there?
I'm using annotation-driven mode with *.dorequest handled by spring DispatchServlet.
想知道那里有什么问题吗？我正在使用注释驱动模式，*.do请求由 spring 处理DispatchServlet。

try this
试试这个
@Controller
@RequestMapping("/basic")
public class HelloWorldController {
@RequestMapping(value="/hello.do", method=RequestMethod.GET)
public ModelAndView helloWorld() {
ModelAndView mav = new ModelAndView();
mav.setViewName("basic/helloWorld");
mav.addObject("message", "Hello World From Phuong!");
return mav;
}
}
and try with the basic/hello.dourl
并尝试使用basic/hello.do网址
The reason is that /basic.do/hellois not going to be handled by your dispatcher servlet as it is not an URL that ends in .do
原因是它/basic.do/hello不会由您的调度程序 servlet 处理，因为它不是以 .do 结尾的 URL
BTW, .html extensions are nicer than .do, IMHO
顺便说一句，.html 扩展名比 .do 好，恕我直言
