spring获取客户端请求的ip地址

第一步：创建maven工程，引入需要的依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

第二步：创建controller

package com.example.demo.controller;
 
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
 
import javax.servlet.http.HttpServletRequest;
 
/**
 * @author zhr_java@163.com
 * @date 2022/3/29 20:50
 */
@RestController
@RequestMapping("/person")
public class PersonController {
 
  @GetMapping("get_person")
  public String getPerson(Integer numbers) {
    String ip = getIp();
    System.out.println("请求的ip是："+ip);
    return ip;
  }
 
  //获取请求对象
  public static HttpServletRequest getRequest() {
    ServletRequestAttributes requestAttributes =
        (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
    if (requestAttributes == null) {
      return null;
    } else {
      return requestAttributes.getRequest();
    }
  }
 
  //获取请求的ip地址
  public static String getIp() {
    HttpServletRequest request = getRequest();
    if (request == null) {
      return "127.0.0.1";
    } else {
      return request.getRemoteHost();
    }
  }
}
 

第三步：启动项目，并在浏览器访问该接口


第四步：做成切面，可以对每个接口的请求次数做出统计
第五步：打包上传到服务器测试
