SpringBoot是做微服务架构非常好的一套框架，下面来讲讲我的第一个SpringBoot项目；

1、依赖

    <properties>
        <spring.boot.version>1.3.2.RELEASE</spring.boot.version>
    </properties>
<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>${spring.boot.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
            <version>${spring.boot.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
            <version>${spring.boot.version}</version>
        </dependency>
        <dependency>
            <groupId>org.assertj</groupId>
            <artifactId>assertj-core</artifactId>
            <version>3.4.1</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>2.5</version>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>${spring.boot.version}</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

2、Application类，这是SpringBoot启动服务的类；

package simple;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import simple.service.ExampleOneService;

/**
 * Created by LK on 2016/4/24.
 */
@SpringBootApplication
public class SimpleApplication implements CommandLineRunner{

    @Autowired
    @Qualifier("exampleOneService")
    private ExampleOneService exampleOneService;

    public void run(String... strings) throws Exception {
        System.out.println(this.exampleOneService.getExampleOneMessage());
        if(strings.length > 0 && strings[0].equals("exitcode")){
            throw new ExitException();
        }
    }
    public static void main(String[] args) {
        SpringApplication.run(SimpleApplication.class,args);
    }
}

3、由于上面需要引用服务才可以获得内容，所以我们也得创建一个服务类；

package simple.service;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

/**
 * Created by LK on 2016/4/24.
 */
@Component
public class ExampleOneService {
    @Value("${name:我的第一个SpringBoot}")  //name:后面的值可以在resources里面的application.properties中配置，如果不配置，那么久默认为程序里面的值
    private String name;

    public String getExampleOneMessage(){
        return "看，" + name;
    }
}

4、上面说application.properties，那么我们还得创建一个这样子的文件，并配置好需要的信息；

name:我的第一个SpringBoot

5、去到

SimpleApplication 类中，右键运行main运行项目，又或者Teminal控制台执行mvn spring-boot:run可以运行项目
