(入門SpringBoot)SpringBoot來臨(一)

1.創建獨立的Spring應用程式.
2.嵌入tomcat,Jetty或者Undertow,無需部署war文件;
3.允許通過Maven來獲取starter;
4.儘可能的自動配置Spring.
5.提供生產就緒型功能,如指標,健康檢查和外部配置.
6.絕對沒有代碼生成,對xml沒有要求配置.

下麵創建一個SpringBoot入門項目:

1.pom.xml

 <!-- AOP -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>
        <!-- web開發包 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!-- 載入測試包 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

2.代碼:

//@SpringBootApplication
@Controller
//啟動spring boot自動裝配.
@EnableAutoConfiguration
public class DemoApplication {

    @RequestMapping("/test")
    @ResponseBody
    public Map<String,Object> test(){
        Map<String,Object> map = new HashMap<String,Object>();
        map.put("key","value");
        map.put("key2","value");
        return map;
    }
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}
