Spring MVC 找出所有的URL映射地址

@Autowired
private RequestMappingHandlerMapping handlerMapping;

@RequestMapping("urls")
public void index(Long id, HttpServletRequest request, HttpServletResponse response)
			throws IOException, ClassNotFoundException {
		Map<RequestMappingInfo, HandlerMethod> map = handlerMapping.getHandlerMethods();
		Iterator<Entry<RequestMappingInfo, HandlerMethod>> iterator = map.entrySet().iterator();
		while (iterator.hasNext()) {
			Entry<RequestMappingInfo, HandlerMethod> entry = iterator.next();
			HandlerMethod hm=entry.getValue();
			
			StringBuffer str=new StringBuffer("请求地址:"+entry.getKey().getPatternsCondition() + "----调用方法:" + hm.getMethod().getName()+"(");
			MethodParameter[] mmm=hm.getMethodParameters();
			for (MethodParameter methodParameter : mmm) {
				str.append(methodParameter.getParameterType().getSimpleName()+",");
			}
			if(str.lastIndexOf(",")>0){
				str.deleteCharAt(str.length()-1);
			}
			str.append(")");
			System.out.println(str);
			response.setCharacterEncoding("utf-8");
			response.setContentType("text/html");
			response.getWriter().write(str+"<br/>");
		}
