一. 创建简单工程
在菜单栏选中File->New->Project 进入以下界面，点击Next

勾选web->Spring Web Starter,点击Next

一个简单的springBoot项目建立完成。
pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<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/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.6.RELEASE</version>

<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>

<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
二. 编写Controller
1).在引导类DemoApplication同级包或者子级包中创建TestControlle
package com.example.demo.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class TestController {
@RequestMapping("/test")
public String test(){
return "ohh~初步访问!";
}
}
注：如果不在同级包或者子级包中创建，则需要在DemoApplication添加包扫描(一般不建议这么做)
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication(scanBasePackages={"com.example.controller"} )
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
2).启动项目，执行测试
执行SpringBoot项目启动
一.命令方式启动
首先执行：mvn clean install
然后执行：mvn spring-boot:run
二.idea方式启动

打开浏览器访问url地址为：http://localhost:8080/demo/test

其中端口和项目路径都是可配，修改application.yml文件
server:
port: 8080
servlet:
context-path: /demo
