获取项目中所有URL--获取swagger上展示的接口信息

有时我们需要接口的一些基本信息，比如接口请求路径，接口请求方式等，我们用这些信息来做判断，或者入库。

我在开发接口权限的时候就遇到了这个问题，之前写的接口很多，现在需要将这些接口信息存到数据库中，

用来做接口的权限操作，经过一番查阅，在此汇总了一下：

@Autowired
    WebApplicationContext applicationContext;

    @RequestMapping(value = "/getAllURL", method = RequestMethod.POST)
    public Object getAllURL() {
        List<Map<String, String>> resultList = new ArrayList<>();

        RequestMappingHandlerMapping requestMappingHandlerMapping = applicationContext.getBean(RequestMappingHandlerMapping.class);
        // 获取url与类和方法的对应信息
        Map<RequestMappingInfo, HandlerMethod> map = requestMappingHandlerMapping.getHandlerMethods();

        for (Map.Entry<RequestMappingInfo, HandlerMethod> mappingInfoHandlerMethodEntry : map.entrySet()) {
            Map<String, String> resultMap = new LinkedHashMap<>();

            RequestMappingInfo requestMappingInfo = mappingInfoHandlerMethodEntry.getKey();
            HandlerMethod handlerMethod = mappingInfoHandlerMethodEntry.getValue();

            resultMap.put("className",handlerMethod.getMethod().getDeclaringClass().getName()); // 类名
            Annotation[] parentAnnotations = handlerMethod.getBeanType().getAnnotations();
            for (Annotation annotation : parentAnnotations) {
                if (annotation instanceof Api) {
                    Api api = (Api) annotation;
                    resultMap.put("classDesc",api.value());
                } else if (annotation instanceof RequestMapping) {
                    RequestMapping requestMapping = (RequestMapping) annotation;
                    if (null != requestMapping.value() && requestMapping.value().length > 0) {
                        resultMap.put("classURL",requestMapping.value()[0]);//类URL
                    }
                }
            }
            resultMap.put("methodName", handlerMethod.getMethod().getName()); // 方法名
            Annotation[] annotations = handlerMethod.getMethod().getDeclaredAnnotations();
            if (annotations != null) {
                // 处理具体的方法信息
                for (Annotation annotation : annotations) {
                    if (annotation instanceof ApiOperation) {
                        ApiOperation methodDesc = (ApiOperation) annotation;
                        String desc = methodDesc.value();
                        resultMap.put("methodDesc",desc);//接口描述
                    }
                }
            }
            PatternsRequestCondition p = requestMappingInfo.getPatternsCondition();
            for (String url : p.getPatterns()) {
                resultMap.put("methodURL",url);//请求URL
            }
            RequestMethodsRequestCondition methodsCondition = requestMappingInfo.getMethodsCondition();
            for (RequestMethod requestMethod : methodsCondition.getMethods()) {
                resultMap.put("requestType",requestMethod.toString());//请求方式：POST/PUT/GET/DELETE
            }
            resultList.add(resultMap);
        }
        return JSONArray.fromObject(resultList);
    }
