SpringMVC项目中获取所有URL到Controller Method的映射

参考链接 https://www.cnblogs.com/yuananyun/archive/2014/08/25/3934371.html

参考上面大神的代码写的，发现他的代码有点小小的问题啊，我这只菜鸟有点小小不懂哈，然后我就Ctrl+C了一下，然后修改一下了啊，改成我寄己可以运行的啊，下面上代码

Controller代码

    @ResponseBody
    @RequestMapping("/url/list/show")
    public String listUrlsShow(){
        Map map =  this.handlerMapping.getHandlerMethods();
        Iterator<?> iterator = map.entrySet().iterator();
        List<RequestToMethodItem> urls=new ArrayList<>();
        while(iterator.hasNext()){
            Map.Entry<RequestMappingInfo, HandlerMethod> entry = (Map.Entry) iterator.next();

            RequestMappingInfo requestMappingInfo = entry.getKey();
            HandlerMethod mappingInfoValue = entry.getValue();
            String controllerName = mappingInfoValue.getBeanType().toString();
            String requestMethodName = mappingInfoValue.getMethod().getName();
            Class<?>[] methodParamTypes = mappingInfoValue.getMethod().getParameterTypes();

            RequestMethodsRequestCondition methodCondition = requestMappingInfo.getMethodsCondition();

            Iterator it=methodCondition.getMethods().iterator();
            String requestType =it.hasNext()?methodCondition.getMethods().iterator().next().name():"";

                    PatternsRequestCondition patternsCondition = requestMappingInfo.getPatternsCondition();
            String requestUrl = patternsCondition.getPatterns().iterator().next();

            RequestToMethodItem item = new RequestToMethodItem(requestUrl,
                    requestType,
                    controllerName,
                    requestMethodName,
                    methodParamTypes);

            urls.add(item);
        }

        return successResponse(urls);
    }

使用到的POJO代码：

RequestToMethodItem.java

public class RequestToMethodItem {
    public String controllerName;
    public String methodName;
    public String requestType;
    public String requestUrl;
    public Class<?>[] methodParmaTypes;

    public RequestToMethodItem(String requestUrl, String requestType, String controllerName, String requestMethodName,
                        Class<?>[] methodParmaTypes) {
        this.requestUrl = requestUrl;
        this.requestType = requestType;
        this.controllerName = controllerName;
        this.methodName = requestMethodName;
        this.methodParmaTypes = methodParmaTypes;
    }


}

好啦好啦，就这些代码啦，撒花~~~

说明一下哈，敲黑板，注意听：

successResponse()方法是我自己封装的哈，功能是把最后得到的结果List，转换成json对象哈，反正最后结果都在urls中啦。可以选择打印撒。。

运行一下哦，come on baby!!!  输入链接，访问访问。。。

下面就是运行结果图啦，散开散开，图有点大鸭
