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);  
        }  
    }  
}
