package com.javawiki.wiki_02;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.core.env.Environment;

@SpringBootApplication
public class Wiki02Application {


    private static final Logger LOG = LoggerFactory.getLogger(Wiki02Application.class);

    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(Wiki02Application.class);
        Environment env = app.run(args).getEnvironment();
        LOG.info("启动成功！！");
        LOG.info("地址: \thttp://127.0.0.1:{}", env.getProperty("server.port"));
    }

}

在main/java/resoures/application.properties编写启动端口

1
server.port=8080

2.接口开发

在项目 main/java/项目名称主目录下新建 一个package，名称为controller

image-20240203230243259

之后新建一个测试类，TestController，编写代码

  • @RestController 返回字符串格式
  • @RequestMapping(“/hello”) // 设置hello接口 @RequestMapping 支持所有的请求方式

package com.javawiki.wiki_02.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController // @RestController 返回字符串格式
public class TestController {

    /*
    * GET,POST,PUT,DELETE
    *
    * */
    @RequestMapping("/hello") // 设置hello接口 @RequestMapping 支持所有的请求方式
    public String hello()
    {
        return  "Hello Wrold";
    }
}

启动项目，访问

1
http://127.0.0.1:8080/hello

3.IDEA自带client测试接口插件

根目录新建 http文件夹，里面新增test.http

POST http://localhost:8080/hello/post
Content-Type: application/x-www-form-urlencoded

name = ZhiHuan

点击既能测试

4.遇到的坑

Springboot用3.2.2 Mybatis需要用3.0.3
