spring boot 第一个例子

spring boot是一个非常好的框架，在这个例子中我感觉到他的简单，配置的简单。
因为我是用maven进行开发的，所以使用的spring boot的maven方式。
pom.xml：

Application:启动

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
//@Configuration
//@EnableAutoConfiguration
//@ComponentScan
@SpringBootApplication//简化了上面的
public class Application { 
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

web:使用@RestController+@RequestMapping就可以达到开发RESTful web services的目的，response只会一直通过response body发送。

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!";
    }
}
