有时候我们需要看系统中所有的接口的uri，我们就可以使用这种方式打印出springboot中的

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.stereotype.Service;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.method.HandlerMethod;
import org.springframework.web.servlet.mvc.method.RequestMappingInfo;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;
import java.util.*;
/**
 * @desc: 获取系统所以的 uri 服务
 * @auth: zhangsy
 * @data: 2019/9/28 9:30
 */
@Service
public class UriMappings implements ApplicationRunner {

    @Autowired
    private WebApplicationContext applicationContext;
    /**
     * @desc: 获取 所以 uri
     * @auth: zhangsy
     * @data: 2019/9/28 9:31
     * @return: 系统所以请求 uri 地址
     */
    public List<String> 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<String> urlList = new ArrayList<>();
        for (RequestMappingInfo info : map.keySet()){
            //获取url的Set集合，一个方法可能对应多个url
            Set<String> patterns = info.getPatternsCondition().getPatterns();
            for (String uri : patterns){
                    urlList.add(uri);
                    System.out.println(uri);
            }
        }
        return urlList;
    }
    /**
     * @desc: 打印uri
     * @auth: zhangsy
     * @data: 2019/9/28 9:31
     */
    @Override
    public void run(ApplicationArguments args) {
      getAllUrl();
    }
}
