对于传统的Web项目，可能大部分都要部署到web容器中，如Tomcat。Spring Boot提供了一种超级简单的部署方式，就是直接将应用打成jar包，在生产上只需要执行java -jar就可以运行了。

一般情况下，如果我们的应用只是作为一个服务、工具类、API的形式存在，那么我们一般将其打包成jar包。而如果我们的应用是一个Web应用，都是打成war包，进行发布，同时如果我们的服务器是Tomcat等轻量级服务器，一般都打成war包进行发布；

我们在Spring Boot整合Mybatis实例一文中已经描述过如何整合Spring Boot和Mybatis，本文我们在上文的基础上来看一下如何将Spring Boot项目打成Jar包并部署运行。项目结构如下：

首先我们需要开发一个控制器来接受我们的Http请求并在浏览器上显示对应的消息。所以我们先定义一个服务接口BlogService，该接口只有一个方法，即获取数据列表：

public interface BlogService  {
    List<BlogType> queryBlogType();
}

我们再定义一个接口的实现类，名为BlogServiceIml，该类实现BlogService接口，具体如下：

@Service
public class BlogServiceIml implements BlogService {
    @Autowired
    private BlogTypeMapper blogTypeMapper;

    /**
     * 获取列表
     * @return
     */
    @Override
    public List<BlogType> queryBlogType() {
        return blogTypeMapper.getAll();
    }
}

注意，定义一个服务类时一定要加上@Service注解。

接下来我们定义一个控制器（Controller），该控制器接受一个请求并以Json的格式返回数据。

@RestController
@RequestMapping(value="/api/blog")
public class BlogController {
    @Autowired
    private BlogService blogService;

    @RequestMapping(value="/blogTypes")
    public List<BlogType> blogTypes(HttpServletRequest request, HttpServletResponse response){
        return blogService.queryBlogType();
    }
}

准备工作就绪，接下来我们开始打包。
第一步：我们需要在pom.xml添加spring-boot-maven-plugin

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

第二步，保存pom.xml，进入pom.xml所在的目录，运行mvn clean package -Dmaven.test.skip=true命令打包。

F:\MyProject\IntelliJ\mybatisxml>mvn clean package -Dmaven.test.skip=true

第三步，打包完成，进入Target目录，使用java -jar命令，运行应用

F:\MyProject\IntelliJ\mybatisxml>cd target

F:\MyProject\IntelliJ\mybatisxml\target>java -jar mybatisxml-0.0.1-SNAPSHOT.jar

程序启动成功之后，在浏览器输入http://localhost:8080/api/blog/blogTypes，如果得到如下结果则表示打包启动成功。
