1、SpringBoot之HelloWord

本項目主要是講創建一個SpringBoot的HelloWorld項目

項目地址：https://github.com/Chakid/SpringBoot-example

該項目直接以maven的方式創建

pom文件中導入相關包：

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.1.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>

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

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

    <!--將應用打包成可執行的jar包-->
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

創建SpringBoot啓動類：

@SpringBootApplication
public class MainApplication {

    /**
     *  Spring應用啓動起來
     */
    public static void main(String[] args) {
        SpringApplication.run(MainApplication.class,args);
    }
}

創建一個控制類

@Controller
public class HelloController {


    @ResponseBody
    @RequestMapping("/hello")
    public String hello(){
        return "Hello SpringBoot";
    }
}

創建好相關類，具體代碼可見項目中的實現，運行啓動類；瀏覽器訪問 http://127.0.0.1:8080/hello
