required a single bean, but 2 were found

项目集成xxljob时，报错：

Parameter 0 of method xxlJobSpringExecutor in com.wf.job.XxlJobAutoConfiguration required a single bean, but 2 were found:
	- xxlJobProperties: defined in URL [jar:file:/C:/Users/777/.m2/repository/com/xx/xx-xxl-job-spring-boot-starter/1.0.0/wf-xxl-job-spring-boot-starter-1.0.0.jar!/com/xx/job/properties/XxlJobProperties.class]
	- xx.xxl-job-com.xx.job.properties.XxlJobProperties: defined in null

因为xxljob组件是自己在xxljob的基础上封装的，然后项目启动报错，

原因是在启动类加 `@ComponentScan` 注解，配置的包扫描路径重复了，导致重新生成两个bean，而且一个bean defined in null.

解决办法就是把包扫描的路径改下，不能有包含关系。
