SpringBoot入門

pom.xml

	<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.1.RELEASE</version>
    </parent>

    <dependencies>
        <!--web功能的起步依賴-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!--熱部署配置-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
        </dependency>
    </dependencies>

idea想使用熱部署的設置

首先
在pom.xml文件中ctrl+shift+alt+/點擊Registry

編寫SpringBoot引導類

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

編寫Controller

@RestController
public class QuickController {
    @RequestMapping("/quick")
    public String quick() {
        return "helloSpringBoot";
    }
}
