整理试用了网上推荐的两种获取springboot框架下所有URL的方法，并稍作调整，直接上代码：

方法1：

package com.xxx.util;


import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.method.HandlerMethod;
import org.springframework.web.servlet.mvc.condition.PatternsRequestCondition;
import org.springframework.web.servlet.mvc.condition.RequestMethodsRequestCondition;
import org.springframework.web.servlet.mvc.method.RequestMappingInfo;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

@RestController
public class UrlCollector {
    @Data
    @AllArgsConstructor
    @NoArgsConstructor
    private class UrlInfo {

        private String url;
        private String method;
        private String desc;
    }

    @Autowired
    WebApplicationContext applicationContext;

    @RequestMapping(value = "v1/getAllUrl", method = RequestMethod.GET)
    public Object getAllUrl() {
        RequestMappingHandlerMapping mapping = applicationContext.getBean(RequestMappingHandlerMapping.class);
        // 获取url与类和方法的对应信息
        Map<RequestMappingInfo, HandlerMethod> map = mapping.getHandlerMethods();


        List<UrlInfo> list = new ArrayList<UrlInfo>();
        for (Map.Entry<RequestMappingInfo, HandlerMethod> m : map.entrySet()) {
            UrlInfo urlInfo = new UrlInfo();
            RequestMappingInfo info = m.getKey();
            HandlerMethod method = m.getValue();
            PatternsRequestCondition p = info.getPatternsCondition();
            for (String url : p.getPatterns()) {
                urlInfo.setUrl(url);
            }
//            map1.put("className", method.getMethod().getDeclaringClass().getName()); // 类名
//            urlInfo.setMethod(method.getMethod().getName());                  // 方法名
            RequestMethodsRequestCondition methodsCondition = info.getMethodsCondition();
            for (RequestMethod requestMethod : methodsCondition.getMethods()) {
                urlInfo.setMethod(requestMethod.toString());
            }

            list.add(urlInfo);
        }

        return list;
    }
}

方法二：

        List<UrlInfo> list = new ArrayList<UrlInfo>();

        for (String beanName : beans.keySet()) {
            Object value = applicationContext.getBean(beanName);
            if (value == null) {
                continue;
            }

            Method[] functions = value.getClass().getMethods();
            for (Method func : functions) {
                UrlInfo urlInfo = new UrlInfo();
                //每个方法必定含有下面的注解中的其中一个
//                ApiOperation apiOperation = AnnotationUtils.findAnnotation(func, ApiOperation.class);   //测试时这里我会报错，原因未知

                    reqMethod = "DELETE";
                } else if (reqMapping != null) {  //mapping 顺序一定要在后面
