对阅读本项目的人来说：
1.巩固基础。top100问题都是比较重要、基础的问题；而且也都是so上很多人优化和投票的，很靠谱。
2.快速学习知识。相对英文原文，本项目的翻译有两个优点：（1）是中文母语，能更好理解；（2）翻译时会对原文做精简，多个答案做整合，阅读起来更有效率
对参与翻译的人来说：
1.参与门槛低，只要能读懂英文文档就行（我会进行优化）；
2.特别适合协作，每个问答独立成一个md，翻译好一个，就上传对应的md文件
3.可以加深自己对一些基础知识的理解
现在一直在持续更新欢迎大家参与，一起来提高自己，享受开源乐趣

个人觉得性价比最高的当属zookeeper，代码不复杂，但是应用广泛。

这个问题我可以来回答！下面是我的GitHub上的可以玩耍并学习的Java开源项目：
1、jw3gparser wucao/jw3gparser: Java解析《魔兽争霸3》游戏录像工具
你玩过魔兽争霸3或者DOTA吗？那么你肯定知道w3g是什么，对，就是war3的录像文件。这个开源项目是用Java解析war3录像文件的工具，可以分析出录像中的很多信息，例如对战地图、玩家的信息（种族、颜色）、玩家APM、聊天信息等。好吧，这个代码是我写的。你可以在代码中学习到IO流、字节码操作、压缩解压等相关技术。
可以配合这些文章阅读代码：
Java解析魔兽争霸3录像W3G文件（一）：Header
Java解析魔兽争霸3录像W3G文件（二）：压缩数据块解压合并
Java解析魔兽争霸3录像W3G文件（三）：解析游戏开始前的信息
Java解析魔兽争霸3录像W3G文件（四）：解析游戏进行时的信息
Java解析魔兽争霸3录像W3G文件（五）：Action和APM计算
2、JDeploy wucao/JDeploy
一个Linux下的Java项目自动化部署工具，主要功能有从版本管理工具拉下代码、Maven打包、启动/停止程序、查看日志。这个也是我写的，代码非常简单，目前在几家互联网公司已经线上使用。你可以在代码中学习到Shell脚本、Maven、版本管理工具、Spring/MyBatis/Spring MVC/Spring Security等相关技术。
对了，这个项目前端用的是 Materializecss 框架，Material Design风格，页面颜值非常高！

我知道的：
java web 方向：
jfinal1.9版本
2.0大量引入了一些其他的东西（为了切片操作，大量使用cglib），虽然大部分代码没变，不过确实越来越臃肿了
后台方向：
ddpush，国人开发的千万级推送框架。
未必真的到千万级，但是绝对值得一看。
安卓、客户端和桌面方向我没有好例子可举。

对于编程来说，最重要的还是编程思想。
怎样提高代码复用率，怎样降低各个模块间的耦合度，怎样设计才能让程序层次清晰，代码干净。
这是我们应该思考的，我们应该考虑清楚再去着手开发。
既然是面向对象，那么对象就是一个个的资源，按照资源来划分模块。
资源间的操作，通过统一的数据接口来进行数据封装。这样只要将数据处理为接口需要的形式，就可以直接利用。
这样就可以避免出现同样的场景，却用了几套不同代码来处理的尴尬情况。

GitHub - javagaorui5944/AisMVC: 一款仿SpringMVC轻便的mvc开发框架
AisMVC,一款仿SpringMVC轻便框架的开发框架
AisMVC,一款仿SpringMVC轻便框架的开发框架
写这个框架的意义： 在过去使用springmvc框架作为项目中的Controller层,springmvc的简洁配置和使用让我们选择了它,但这个框架我用着也发现了它也有很多冗余功能的地方。我们团队开发web项目一般采用前后端分离,所以后端的的Controller层的功能仅仅只有提供ajax接口,页面集成后的跳转,过滤器和拦截器,所以我就想着自己写一款仿springmvc的mvc框架作为自己和团队以后的开发中小型项目的框架,舍掉冗余的部分,只要项目中实际需要的功能。
