分析问题：

原因是加载了2次配置文件

之前的错误配置如下：在limp-dubbo-context.xml 又导入了其他的3个配置文件，启动provider时候导致多次加载；

猜测：provider启动的时候加载的是 META-INF/spring/\*.xml 下的所有配置文件。

![70][]

解决方案：注释掉导入配置的文件即可

\-----------------------------------------------其他技能点---------------------------------------------------------

provider（开发环境）启动配置类，可以这么配置
