因SpringBootApplication指定scanBasePackages后，出現問題

在使用mybatis 二級緩存的時候，當擴大了scanBasePackages范圍后，出現了如下問題：

@SpringBootApplication(scanBasePackages = "com.zhenhunfan.itoken"})
@EnableEurekaClient
@MapperScan(basePackages = {"com.zhenhunfan.itoken.service.posts.mapper","com.zhenhunfan.itoken.common.mapper"})
public class ServicePostsApplication {
    public static void main(String[] args) {
        SpringApplication.run(ServicePostsApplication.class,args);
    }
}

解決方法：精確定位scanBasePackages范圍

@SpringBootApplication(scanBasePackages = {"com.zhenhunfan.itoken.common.context","com.zhenhunfan.itoken.service.posts"})
@EnableEurekaClient
@MapperScan(basePackages = {"com.zhenhunfan.itoken.service.posts.mapper","com.zhenhunfan.itoken.common.mapper"})
public class ServicePostsApplication {
    public static void main(String[] args) {
        SpringApplication.run(ServicePostsApplication.class,args);
    }
}
