Spring Boot打Jar包部署

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][Spring Boot_Mybatis]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：

![这里写图片描述][70]  
  
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][http_localhost_8080_api_blog_blogTypes]，如果得到如下结果则表示打包启动成功。
