Springboot Getting Started-1 (Hello Word Boot)

1, create a MAVEN project, add a parent, the code is as follows

<parent>        <groupId>org.springframework.boot</groupId>        <artifactId> spring-boot-starter-parent</artifactid>        <version>1.3.4.RELEASE</version>    </parent >

2. Add a dependency

<dependencies>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>         </dependency>         </dependencies >    

　　3, configure the Java version, if not filled, the default 1.6

<build><!--Configuration Java version is not configured, the default parent class is configured with 1.6-->    <pluginManagement>      <plugins>        < plugin>          <artifactId>maven-compiler-plugin</artifactId>          <configuration>            < source>1.7</source>            <target>1.7</target>          </configuration>        </plugin >      </plugins>    </pluginManagement>  </build>

　　4. Create a new Java file

　　

 Packagecom.test;Importorg.springframework.boot.SpringApplication;Importorg.springframework.boot.autoconfigure.EnableAutoConfiguration;Importorg.springframework.web.bind.annotation.RequestMapping;ImportOrg.springframework.web.bind.annotation.RestController;/*** @RestController equivalent to @controller and @requestbody **/@RestController @enableautoconfiguration Public classHellocontroller {@RequestMapping ("/hello")     PublicString Hello () {return"Hello Word springboot"; }         Public Static voidMain (string[] args) {Springapplication.run (hellocontroller.class, args); }}

The last run runs
