* 说说JVM内存模型。
* 线程的程序计数器是干什么用的?
* 说说堆里面的垃圾回收算法?为什么新生代用复制算法,老年代用标记整理、标记压缩?
* 了解CMS这个垃圾回收器吗?说说它的工作流程?
* CMS在并发标记的时候,用户线程也会不停的产生一些大对象,Remark再次标记的时候可能会花上很多时间,说说你的优化方案?(我:???)
* 说说java线程池的工作流程?
* 看你项目用过dubbo,dubbo底层是怎么通讯的呢?
* 说说NIO?Selector上都能注册一些什么事件?知道Channel读、写数据是怎么实现的吗?
* 让你来实现一个类似于dubbo的RPC框架,说说你的思路?(懵了)
* dubbo源码看过吗?(没有。。。)dubbo的负载均衡有几种?
* 让你自己来实现一个带权重的轮询负载均衡,能说说你的思路或者写个伪代码也行。(放弃治疗了,我太菜了)
* 看你项目用了springboot,源码有了解过吗?知道为什么springboot能实现快速开发么?
* springboot内嵌tomcat容器,你知道是怎么做到的吗?
* spring整合dubbo的过程是怎样的?(懵)那你说说springioc容器是怎么创建对象的?
* BeanPostProcessor了解吗?如果我要给一个对象注入spring的组件,应该怎么做?
* 说说springmvc的流程?
