@yuanyuancin 这几天会看下，另外方便加下开发者沟通群吗？这是个比较重要的 adapter，希望能再群里能更方便的沟通。

这个feature的核心是为了解决serverless合并部署场景下，多biz使用logback、支持biz独立的日志配置、上下文隔离；

需要增加sample验证一下方案可行性（可以参考log4j2 sample搭建在工程sample目录下）验证过程中可能需要考虑下：

1. 方案中的 Adapter 使用 ThreadLocal 缓存不同 biz 不同 logger context可能不可靠，模块安装不一定会单独线程，模块卸载时的线程也不会复用安装时的线程。

2. 如果如预期在启动期为不同 biz 创建了不同 logger context，并使用biz自己的日志配置configure context，需要机制来确保在getLogger时，根据不同biz获取不同logger context，否则启动期创建的logger context可能不会生效。

1. Adapter的能力合并到 ContextSelector就行啦，不需要两个类
2. 不只是biz启动期会 getContext，运行期，需要考虑运行期如果tccl非biz classloader的情况，考虑通过 callerClass classloader？
3. ContextSelector.detachLoggerContext 实现remove逻辑
4. context name可以使用 String contextName = Integer.toHexString(System.identityHashCode(bizClassloader));
