Question

@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'的结果是12345

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

Answer 1

只需将其指定为@PathVariable("id") - 如果没有负责解析参数值的HandlerMethodArgumentResolver尝试通过参数名称找出参数值，则参数名称（id）在编译期间会丢失（除非调试编译期间符号打开，通常不是。

Answer 2

@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;
}

以上代码对我来说很好。请以类似的方式使用。

Spring MVC使用@PathVariable映射查询参数而不是URI模板值
