1. http://springboot.javaboy.org/2019/0412/springboot-init

   maven 建立springboot2

   

建立完成後，在 pom.xml 檔案中，添加如下依賴：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.4.RELEASE</version>
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>
           

@EnableAutoConfiguration
@RestController
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
    @GetMapping("/hello")
    public String hello() {
        return "hello";
    }
}
