Spring Mvc获取所有注册URL

废话不多说，直接上代码，以下两种方式获取SpringMVC中注册的URL。

@Controller
public class UrlsController {
    // 方法 1
    @ResponseBody
    @RequestMapping("/urls1")
    public Object getUrlMapping(HttpServletRequest request) {
        WebApplicationContext wc = RequestContextUtils.getWebApplicationContext(request);
        RequestMappingHandlerMapping rmhp = wc.getBean(RequestMappingHandlerMapping.class);
        Map<RequestMappingInfo, HandlerMethod> map = rmhp.getHandlerMethods();
        List<String> urls = new ArrayList<>(map.size());
        for (RequestMappingInfo info : map.keySet()) {
            System.out.println(info.getPatternsCondition().toString() + "," + map.get(info).getBean().toString());
            urls.add(info.getPatternsCondition().toString());
        }
        return urls;
    }

    // 方法 2
    @Autowired
    private RequestMappingHandlerMapping handlerMapping;

    @ResponseBody
    @RequestMapping("/urls2")
    public Object index(Long id, HttpServletRequest request, HttpServletResponse response)
            throws IOException, ClassNotFoundException {
        Map<RequestMappingInfo, HandlerMethod> map = this.handlerMapping.getHandlerMethods();
        List<String> urls = new ArrayList<>(map.size());
        for(Map.Entry<RequestMappingInfo, HandlerMethod> entry  : map.entrySet()) {
            System.out.println(entry.getKey() + System.lineSeparator() + entry.getValue());
            urls.add(entry.getKey().toString());
        }
        return urls;
    }
}

对了注意不能Response返回RequestMappingInfo, HandlerMethod对象，否则会报错。其他web.xml以及springmvc的配置都需要加上。
