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>

1. 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);
    }
}

1. 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);
    }
}

1. 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";    
    }
}

1. Resource下新建文件：application.properties

server.port=${por
