@RequestMapping(value = "/account/{id}", method = RequestMethod.GET)
public ModelAndView getAccount(@PathVariable String id)
        throws ProfileNotFoundException {
   System.out.println(id);
   return null;
}

.../account/12345 结果为空

.../account/test?id=12345 '12345' 结果为 12345

不知道如何解决这个问题，但我希望第一个链接而不是第二个链接工作。这是我的 webmvc-config.xml

只需将其指定为@PathVariable("id")- 没有负责解析参数值的 HandlerMethodArgumentResolver 尝试通过参数名称找出参数值，但参数名称（id）在编译期间会丢失（除非调试符号在编译期间打开，这通常它不是）。

@RequestMapping(value = "/authors/{authorId}")
public ModelAndView getAuthorById(@PathVariable String authorId) {
    Author author = bookService.getAuthorById(authorId);
    ModelAndView mav = 
        new ModelAndView("bookXmlView", BindingResult.MODEL_KEY_PREFIX + "author", author);
    return mav;
}

上面的代码对我来说很好。请以类似方式使用。
