SpringBoot学习笔记-maven构建SpringBoot项目

在pom.xml里添加以下

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
        <version>2.1.5.RELEASE</version>
    </parent>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

然后新建一个类作为启动器

package com.boot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class SpringBootDemo {
    
    
    public static void main(String[] args) {
    
    
        SpringApplication.run(SpringBootDemo.class, args);
    }
    @RequestMapping("/")
    String home() {
    
    
        return "hello world";
    }

}

直接启动即可
