獲取項目中所有URL--獲取swagger上展示的接口信息

有時我們需要接口的一些基本信息，比如接口請求路徑，接口請求方式等，我們用這些信息來做判斷，或者入庫。

我在開發接口權限的時候就遇到了這個問題，之前寫的接口很多，現在需要將這些接口信息存到數據庫中，

用來做接口的權限操作，經過一番查閱，在此匯總了一下：

@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);
        // 獲取url與類和方法的對應信息
        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()); // 類名
            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]);//類URL
                    }
                }
            }
            resultMap.put("methodName", handlerMethod.getMethod().getName()); // 方法名
            Annotation[] annotations = handlerMethod.getMethod().getDeclaredAnnotations();
            if (annotations != null) {
                // 處理具體的方法信息
                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);//請求URL
            }
            RequestMethodsRequestCondition methodsCondition = requestMappingInfo.getMethodsCondition();
            for (RequestMethod requestMethod : methodsCondition.getMethods()) {
                resultMap.put("requestType",requestMethod.toString());//請求方式：POST/PUT/GET/DELETE
            }
            resultList.add(resultMap);
        }
        return JSONArray.fromObject(resultList);
    }
