接着上一篇博客：第一步：提供一个服务实例出来：micro-provider(服务提供者)，可以单独的去部署到服务器上。 ①：建个SpringBoot的项目，需要的依赖如下： ②：配置下mybatis的数据源和相应的驼峰映射： ③：写相应的实体类： ④：写相应的Mapper接口，由于这个mapper是交给Spring容器控制和管理的，所以说在启动类上加一个扫描Mapper接口的注解，然后这个这个接口就会生产接口的代理实现类去交给Spring容器进行管理。 ⑤：在Mapper接口中写一个根据id查出用户信息的方法： ⑥：由于这个接口要形成映射的，由于现在写的是单表的操作，就不写xml了，直接用注解的方式来进行编写如下：如果这里用@Autowired的话，它会在Spring容器中会检测是否会有这样的对象动态的已经添加到容器中。这个@Autowired标注的对象不像@Service一样标在类上就能识别。而，在启动类上用的MapperScaner用的注解是在运行的时候才能识别，所以说这里用@Resource注解来注入，@Resource注解不会去找，它相当于使用的是java的东西（import javax.annotation.Resource)。就和Spring不会挂钩，但是它也会去Spring容器中去找。这里会按类型装，不会按名称装。 @Resource注解和
