获取SpringMVC的映射路径

public String init(HttpServletRequest request, HttpServletResponse response){
    List<String> uList = new ArrayList<String>();//存储所有url集合
    WebApplicationContext wac = (WebApplicationContext) request.getAttribute(DispatcherServlet.WEB_APPLICATION_CONTEXT_ATTRIBUTE);//获取上下文对象
    RequestMappingHandlerMapping bean = wac.getBean(RequestMappingHandlerMapping.class);//通过上下文对象获取RequestMappingHandlerMapping实例对象
    Map<RequestMappingInfo, HandlerMethod> handlerMethods = bean.getHandlerMethods();
    for (RequestMappingInfo rmi : handlerMethods.keySet()) {
        PatternsRequestCondition prc = rmi.getPatternsCondition();
        Set<String> patterns = prc.getPatterns();
        for (String uStr : patterns) {
            uList.add(uStr);
        }
    }
}
