The following are potential configuration items that you may want to fix:

1 : debmirror package is not installed, it will be required to manage debian deployments and repositories

2 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

以上两个是关于debian系统的错误，请忽略

先自我介绍一下，小编13年上海交大毕业，曾经在小公司待过，也去过华为、OPPO等大厂，18年进入阿里一直到现在。

深知大多数初中级Java工程师，想要提升技能，往往是自己摸索成长或者是报班学习，但对于培训机构动则近万的学费，着实压力不小。自己不成体系的自学效果低效又漫长，而且极易碰到天花板技术停滞不前！

因此收集整理了一份《Java开发全套学习资料》送给大家，初衷也很简单，就是希望能够帮助到想自学提升又不知道该从何学起的朋友，同时减轻大家的负担。

由于文件比较大，这里只是将部分目录截图出来，每个节点里面都包含大厂面经、学习笔记、源码讲义、实战项目、讲解视频
