我想问一下各个模块加载自己的上下文的时候，为什么会出现重复加载某个类的情况 #1329

如题。在各个模块加载自己上下文时控制台会大量打印“Component was already registered：xxxx”。
重复的扫描让项目启动时间变得很长。二三十分钟启动真的很难以接受。

检查一下是不是配置的ComponentScan里的扫描路径有重叠

没有重叠，出现问题的是当前项目下的common-dal中的mapper类。通过MapperScan指定了扫描路径，但是在SpringContextInstallStage类的doRefreshSpringContext方法中，多线程去刷新各个模块上下文（ctx.refresh()）的时候，应该是每个线程都重复去扫描了

@xycf2233 你好，可以给出一个示例代码来复现这个问题吗
