1. pom.xml中增加配置
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.0.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
2. 创建启动类
创建package learningops.urlshortener
package learningops.urlshortener;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
/**
* @author learningops
* @date 01/03/2018
*/
@SpringBootApplication
@ComponentScan
public class Application implements CommandLineRunner {
@Override
public void run(String... args) throws Exception {
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
3. 创建Controller
创建一个package learningops.urlshortener.controller
package learningops.urlshortener.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
/**
* @author learningops
* @date 22/03/2018
*/
@Controller
public class IndexController {
@RequestMapping("/")
@ResponseBody
String home() {
return "Hello World!";
}
}
4. 运行
mvn spring-boot:run
