一、springboot官方demo开发

1. 依赖包和父：pom.xml

<dependencies>     <dependency>         <groupId>org.springframework.boot</groupId>         <artifactId>spring-boot-starter-parent</artifactId>         <version>2.7.14</version>     </dependency>     <dependency>         <groupId>org.springframework.boot</groupId>         <artifactId>spring-boot-starter-web</artifactId>         <version>2.7.14</version>     </dependency> </dependencies> 

2. 新建 SampleController.java

import org.springframework.boot.*; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody;  @Controller @EnableAutoConfiguration public class SampleController {     @RequestMapping("/")     @ResponseBody     String home(){         return "Hello World!";     }      public static void main(String[] args) {         SpringApplication.run(SampleController.class,args);     } } 

3. 运行结果
   
   说明：内置了web服务器

二、使用SpringBoot开发get方法接口

返回cookie信息的get接口开发

1. 新建Application.java 入口

import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.ComponentScan;  @SpringBootApplication @ComponentScan("com.course.server") public class Application {     public static void main(String[] args) {         SpringApplication.run(Application.class,args);     } } 

2. com.course.server 新建MyGetMethod.java

@RestController public class MyGetMethod{     @RequestMapping(value="/getCookies",method=RequestMethod.GET)     public String getCookies(){         return "恭喜你获得cookies信息成功";         } } 

3. Resource下新建文件：application.properties

server.port=${port:8888} 

4. 启动后访问
   

5. 获得cookies
   修改com.course.server.MyGetMethod.java 代码：

package com.course.server; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; import javax.servlet.http.Cookie; import javax.servlet.http.HttpServletResponse;  @RestController public class MyGetMethod {     @RequestMapping(value = "/getCookies",method= RequestMethod.GET)     public String getCookies(HttpServletResponse response){         // HttpServletRequest 装请求信息得类         // HttpServletResponse 装响应信息得类         Cookie cookie = new Cookie("login", "true");         response.addCookie(cookie);         return "恭喜你获得cookies信息成功";     } } 

运行：

三、一个要求携带cookie信息访问的get接口开发

1. MyGetMethod.java 新增方法：

@RestController public class MyGetMethod{     @RequestMapping(value="/get/with/Cookies",method=RequestMethod.GET)     public String getWithCookies(HttpServletRequest request){         // HttpServletRequest 装请求信息的类         // HttpServletResponse 装响应信息的类         Cookie[] cookies = request.getCookies();         if(Objects.isNull(cookies)){             return "你必须携带cookies信息来";                 }         for(Cookie cookie:cookies){             if(cookie.getName().equals("login") &&              cookie.getValue().equals("true")){                  return "恭喜你访问成功！";                         }                         }         return "你必须携带cookies信息来";         } } 

2. Jemeter访问
   1）加一个线程组
   2）加一个HTTP请求
   3）加一个HTTP Cookie管理器
   
   4）加一个查看结果树
   

四、需要携带参数的get请求两种开发方式

4.1 方式1：url：key=value&key=value

@RestController public class MyGetMethod{     @RequestMapping(value="/get/with/param",method=RequestMethod.GET)     public Map<String,Integer> getList(@RequestParam Integer start,                                        @RequestParam Integer end){         Map<String,Integer> myList = new HashMap<>();         myList.put("鞋",500);         myList.put("衣服",200);         myList.put("干脆面",1);         return myList;                                                                      } } 

结果：

4.2 方式2：url：ip:port/get/with/param/10/20

@RequestMapping(value = "/get/with/param/{start}/{end}",method = RequestMethod.GET) public Map<String,Integer> getList(@RequestParam(required = false) Integer start,                                    @RequestParam(required = false) Integer end){     Map<String,Integer> myList = new HashMap<>();     myList.put("鞋",500);     myList.put("衣服",200);     myList.put("干脆面",1);     return myList; } 

结果：

五、使用SpringBoot开发post方法接口

1. 新增MyPostMethod.java

import io.swagger.annotations.Api; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import javax.servlet.http.Cookie;  @RestController @RequestMapping("/v1") public class MyPostMethod{     // 这个变量用来装我们的cookies信息     private static Cookie cookie;     // 用户登录成功获取到cookies，然后再访问其他接口获取到列表          @RequestMapping(value="/login",method=RequestMethod.POST)     @ApiOperation(value="登陆接口，成功后获取cookies信息",httpMethod="POST")     public String login(HttpServletResponse response,                         @RequestParam(value="userName",required=true) String userName,                         @RequestParam(value="password",required=true) String password){         if(userName.equals("zhangsan")&&password.equals("123456")){             cookie = new Cookie("login","true");             response.addCookie(cookie);             return "恭喜你登录成功了！";         }         return "用户名或者密码错误！";     } } 

2. 在Jmeter中测试该接口
   
   
   
   

六、Cookie验证和返回用户列表的post接口开发

1. 新增lombok依赖

<dependency>     <groupId>org.projectlombok</groupId>     <artifactId>lombok</artifactId>     <version>RELEASE</version>     <scope>compile</scope> </dependency> 

2. 新增类 com/course/bean/User.java

package com.course.bean; import lombok.Data;  @Data public class User {     private String userName;     private String password;     private String name;     private String age;     private String sex; } 

3. 新增类 com/course/server/MyPostMethod.java

package com.course.server; import com.course.bean.User; import org.springframework.web.bind.annotation.*; import javax.servlet.http.Cookie; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;  @RestController @RequestMapping("/v1") public class MyPostMethod {     // 这个变量用来装我们的cookies信息     private static Cookie cookie;     // 用户登录成功获取到cookies，然后再访问其他接口获取到列表      @RequestMapping(value="/login",method= RequestMethod.POST)     public String login(HttpServletResponse response,                         @RequestParam(value="userName",required=true) String userName,                         @RequestParam(value="password",required=true) String password){         if(userName.equals("zhangsan")&&password.equals("123456")){             cookie = new Cookie("login","true");             response.addCookie(cookie);             return "恭喜你登录成功了！";         }         return "用户名或者密码错误！";     }      @RequestMapping(value="/getUserList",method = RequestMethod.POST)     public String getUserList(HttpServletRequest request,                             @RequestBody User u){         // 获取cookies         Cookie[] cookies = request.getCookies();         // 验证cookies是否合法         for (Cookie c:cookies){             if (c.getName().equals("login") && c.getValue().equals("true") && u.getUserName().equals("zhangsan") && u.getPassword().equals("123456")){                 User user = new User();                 user.setName("lisi");                 user.setAge("14");                 user.setSex("man");                 return user.toString();             }         }         return "参数不合法";     } } 

4. 启动Application.java
5. 使用Jemeter测试接口
   1）新建线程组
   2）新增HTTP Header Manager
   
   3）新增HTTP Cookie Manager
   
   4）新增HTTP Request
   
   5）添加结果树
