day01 Spring Boot起步练习

1.在idea中新建一个空项目，添加一个Spring Initializr模块

2.在pom.xml中添加以下配置

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

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

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

3.在自动生成的java package下新建一个control包，写一个controller类

@RestController
public class HelloController {
    @RequestMapping(value="/hello",method = RequestMethod.GET)
    public String getHello(){
        return"Hello Spring Boot";
    }
}

（类上面RestController注解不要遗漏）

4.运行DemoApplication类（模块创建自动生成）
