Springboot+post请求接口

本文是Springboot+post请求接口的生成，包含了带cookie 和参数发送post请求。新增lombok框架，lombok的使用可以不用在类中添加成员变量的get/set方法。框架自带了相关方法。如不需要再添加以下内容

   public String getUsename() {
        return usename;
    }

    public void setUsename(String usename) {
        this.usename = usename;
    }

<dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.14</version>
        </dependency>
    </dependencies>

java post请求代码如下

package com.course.server;

import com.course.bean.User;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import jdk.internal.org.objectweb.asm.tree.analysis.Value;
import org.springframework.web.bind.annotation.*;

import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@RestController
@Api(value = "/", description = "这是我全部的post请")
@RequestMapping("/V1")
public class MyPostMethod {
    //这个变量用来装我们的cookies信息
    private static Cookie cookie;
    //模拟场景：用户登录成功获取到cookies,然后访问其他接口获取到列表

    /**
     * 模拟用户登录场景
     * @param response
     * @param userName
     * @param password
     * @return
     */
    @RequestMapping(value = "/login", method = RequestMethod.POST)
    @ApiOperation(value = "登录接口，成功登录后获取cookies", httpMethod = "POST")
    public String login(HttpServletResponse response,
                        @RequestParam(value = "username", required = true) String userName,
                        // @RequestParam(value = "username1",required = true)String userName,
                        // @RequestParam传递的参数格式是param格式
                        // username1和前端传递的参数一致，
                        //String userName,可以和前端不一致
                        @RequestParam(value = "password", required = true) String password) {
        if (userName.equals("zhangshan") && password.equals("111111")) {
            cookie = new Cookie("login", "true");
            response.addCookie(cookie);
            return "恭喜你登录成功";
        } else
            return "用户名或密码错误";

    }

    /**
     * 携带cookie的指定用户获取用户列表信息  
     * @param request
     * @param user
     * @return
     */
    @RequestMapping(value = "/getUserList", method = RequestMethod.POST)
    @ApiOperation(value = "获取用户列表", httpMethod = "POST")
    public String getUserList(HttpServletRequest request, @RequestBody User user) {
//必须写上HttpServletRequest reques，或者cookie 值无法带上cookie值  @RequestBody需要传递的参数格式应该是json格式

        //获取cookies
        User user1 = new User();
        Cookie[] cookies = request.getCookies();//获取cookie值
        for (Cookie cookie : cookies) {
            if (cookie.getName() .equals("login" )&& cookie.getValue().equals("true") &&
                    user.getName().equals("zhangshan") && user.getPassword().equals("111111")) {

                user1.setUsename("lisi");
                user1.setAge("18");

                return user1.toString();
            }

        }

        return "参数不合法";

    }

}

User类（用户列表中返回的信息）

package com.course.bean;
import lombok.Data;
@Data
public class User {
    private String usename;
    private  String password;
    private String name;
    private  String age;
    //以下内容 因为引入了lombox框架而不需要再添加成员变量的get/set方法。
//    public String getUsename() {
//        return usename;
//    }
//
//    public void setUsename(String usename) {
//        this.usename = usename;
//    }
//
//    public String getPassword() {
//        return password;
//    }
//
//    public void setPassword(String password) {
//        this.password = password;
//    }
//
//    public String getName() {
//        return name;
//    }
//
//    public void setName(String name) {
//        this.name = name;
//    }
//
//    public String getAge() {
//        return age;
//    }
//
//    public void setAge(String age) {
//        this.age = age;
//    }
}

main入口

        import org.springframework.boot.SpringApplication;
        import org.springframework.boot.autoconfigure.SpringBootApplication;
        import org.springframework.context.annotation.ComponentScan;

@ComponentScan("com.course")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
