    [2018-06-13 02:46:01,031] Artifact chinasofti-dubbo-lp-boss-consumer:war exploded: Artifact is deployed successfully

解决方案：

配置一A：

配置二B
    <import resource="classpath*:META-INF/**/limp-plug-spring-common-*.xml" />

两个配置只有一个字符之差，项目启动时使用A方式就启动不了，报以下未加载

实际使用A方式，在spring里为精确匹配，不能匹配通配符，B方式才可以配匹通配符。

解决方案：B方案，动态导入，插件动态化配置
