Spring bootの最初の例

Spring bootはとても良いフレームワークで、この例では彼の簡単さ、配置の簡単さを感じました.私はmavenで開発しているのでspring bootのmaven方式を使っています.pom.xml:

アプリケーション:起動

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

//@Configuration
//@EnableAutoConfiguration
//@ComponentScan
@SpringBootApplication//      
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

Web:@RestController+@RequestMappingを使用すると、RESTful webサービスを開発する目的を達成できます.responseはresponse bodyを通じて送信されるだけです.

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.sunhuwh.springboot.service.DemoService;

@RestController
@RequestMapping
public class IndexController {

    @Autowired
    private DemoService demoService;

    @RequestMapping("/")
    public String index(){
        demoService.test();
        return "hello world!";
    }

}
