背景

获取运行中项目对外提供的接口信息,免去人工统计操作

实现

package it.ssm.controller;



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

import com.alibaba.fastjson.JSON;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
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;




@Controller
@RequestMapping("/servlet")
public class getServlet{

    @Autowired
    private RequestMappingHandlerMapping requestMappingHandlerMapping;

    @ResponseBody
    @RequestMapping("/index")
    public String getServlet()  {

        List<HashMap<String, String>> urlList = new ArrayList<HashMap<String, String>>();

        Map<RequestMappingInfo, HandlerMethod> map = requestMappingHandlerMapping.getHandlerMethods();
        for (Map.Entry<RequestMappingInfo, HandlerMethod> m : map.entrySet()) {
            HashMap<String, String> hashMap = new HashMap<String, String>();
            RequestMappingInfo info = m.getKey();
            HandlerMethod method = m.getValue();
            PatternsRequestCondition p = info.getPatternsCondition();
            for (String url : p.getPatterns()) {
                hashMap.put("url", url);
            }
            hashMap.put("className", method.getMethod().getDeclaringClass().getName()); // 类名
            hashMap.put("method", method.getMethod().getName()); // 方法名
            RequestMethodsRequestCondition methodsCondition = info.getMethodsCondition();
            String type = methodsCondition.toString();
            if (type != null && type.startsWith("[") && type.endsWith("]")) {
                type = type.substring(1, type.length() - 1);
                hashMap.put("type", type); // 方法名
            }
            urlList.add(hashMap);
        }

        String results = JSON.toJSONString(urlList);
        return results;

    }
}

效果
