10.SpringBoot接口开发实战

SpringBoot接口开发实战

1.pom中添加SpringBoot

 
        org.springframework.boot
        spring-boot-starter-parent
        2.5.6

2.配置swagger-ui、lombok所需要的依赖

        2.9.2
        11
        11
           


            io.springfox
            springfox-swagger2
            ${springfox-swagger2-version}
        
        
            io.springfox
            springfox-swagger-ui
            ${springfox-swagger2-version}
        
        
            com.github.xiaoymin
            swagger-bootstrap-ui
            1.9.6
        
        //方便使用get、set方法
            org.projectlombok 
            lombok
       	 

3.创建application类

package Test;

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

@SpringBootApplication//目的是开启自动配置
@ComponentScan(value = {"getMethod","Config","postMethod"})
//设置扫描类
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class,args);
    }
}

4.resources下新建application.properties,填写配置

server.port=${port:8888}

5.编写被扫描类及方法

a:get方法类

package getMethod;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;

import javax.servlet.http.cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.net.cookieStore;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Objects;

@RestController//表明是被扫描的类
@Api(value = "/")//设置访问该类的路径
public class getcookies {
    @RequestMapping(value = {"/getcookies"})//设置方法路径
    @ApiOperation(value = "獲取cookies get請求", httpMethod = "GET")//设置swagger接口文档中方法的描述，请求方式
    public String getcookies(HttpServletResponse response) {
        cookie cookie = new cookie("login", "true");
        response.addcookie(cookie);
        return "恭喜獲得cookies！";
    }

    @RequestMapping(value = {"/needcookies"})
    @ApiOperation(value = "傳送cookies get請求", httpMethod = "GET")
    public String needcookies(HttpServletRequest request) {
        cookie[] cookies = request.getcookies();
        if (Objects.isNull(cookies)) {
            return "缺少cookies信息！";
        }
        for (cookie cookie1 : cookies) {
            if ((cookie1.getName().equals("login")) && cookie1.getValue().equals("true")) {
                return "携帶正確登錄信息，恭喜成功！";
            }
        }
        return "cookie信息錯誤！";
    }

    //第一種需要蠶食URl方式  url+?key=value&
    @RequestMapping(value = {"/needParams01"})
    @ApiOperation(value = "傳遞參數  url+?key=value&get請求", httpMethod = "GET")
    public Map needParams01(@RequestParam(value = "start", required = true) Integer start, @RequestParam(value = "end", required = true) Integer end) {
        Map map = new HashMap<>();
        map.put("可樂", 3);
        map.put("薯條", 7);
        map.put("漢堡", 10);
        return map;
    }

    //第二種需要蠶食URl方式  url/value/value2
    @RequestMapping(value = {"/needParams02/{start}/{end}"})
    @ApiOperation(value = "傳遞參數 url/value/value2get請求", httpMethod = "GET")
    public Map needParams02(@PathVariable Integer start, @PathVariable Integer end) {
        Map map = new HashMap<>();
        map.put("可樂", 3);
        map.put("薯條", 7);
        map.put("漢堡", 10);
        return map;
    }
}

b:post方法类

package postMethod;

import Unity.User;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

import javax.servlet.http.cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Objects;

@RestController
@Api(value = "/")
public class returncookies {
    @RequestMapping("/postReturncookies")
    @ApiOperation(value = "登錄接口，回返token", httpMethod = "POST")
    public String postReturncookies(HttpServletResponse response, @RequestParam(value = "UserName", required = true) String UserName, @RequestParam(value = "PassWord", required = true) String PassWord) {
        if (UserName.equals("lh") && PassWord.equals("123456")) {
            cookie cookie = new cookie("login", "true");
            response.addcookie(cookie);
            return "登錄成功";
        }
        return "登錄失敗，賬號或者密碼錯誤！";
    }

    @RequestMapping("/postReturnUserList")
    @ApiOperation(value = "登錄接口，回返token", httpMethod = "POST")
    public String postReturnUserList(HttpServletRequest request,HttpServletResponse response, @RequestBody User u) {
        cookie[] cookies = request.getcookies();
        if (Objects.isNull(cookies)) {
            return "缺少cookies!";
        }
        for (cookie cookie : cookies) {
            if (cookie.getName().equals("login") && cookie.getValue().equals("true")) {
                if (u.getUserName().equals("lh")
                        && u.getPassWord().equals("123456")) {
                    User c = new User();
                    c.setAge("18");
                    c.setSex("男");
                    c.setUserName("lh");
                    c.setPassWord("123456");
                    c.setName("六號");
                    return c.toString();
                }
                return "登錄失敗，賬號或者密碼錯誤！";
            }
        }
        return "登錄失敗，cookies不正確！";
    }
}

6.方法中用到的实体类

package Unity;

import lombok.Data;

@Data
public class User {
    private String name;
    private String age;
    private String sex;
    private String UserName;
    private String PassWord;
}

7.运行Application类、浏览器打开localhost:8888/doc.html
