添加maven依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>springBoot</groupId>
    <artifactId>springBoot</artifactId>
    <packaging>jar</packaging>
    <version>0.0.1-SNAPSHOT</version>
    <name>springBoot Maven Webapp</name>
    <url>http://maven.apache.org</url>
    
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.0.RELEASE</version>
    </parent>
    
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>
    
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>
    <build>
        <finalName>springBoot</finalName>
    </build>
</project>

创建一个启动类

package com.wyl.boot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {
    
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
    
}

创建一个请求类

package com.wyl.boot.MyFirstController;

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

@RestController
@RequestMapping("/first")
public class FirstController {
    
    @RequestMapping(value = "/hello", produces = "application/json;charset=UTF-8")
    private String selectPriceAccount() {
        return "hello world";
    }

}

启动项目，试着访问下

给项目起个名字，换个端口试试（注意yaml格式）

spring:
  application:
    name: springBoot
server:
  port: 8089
  servlet:
    context-path: /springBoot

重启项目，访问下
