getty

一个完全基于java 实现的高性能网络框架。

简介

1、getty是完全基于java nio封装的高性能网络框架。

2、getty可在项目中使用,也可以用于帮助你更好的学习java nio

3、getty完全开源,基于 Apache License 2.0 开源协议。

4、getty的目的是为了降低对java socket nio的使用成本,帮助提高工作效率。

getty名称的由来

取名getty主要是作者过去使用netty比较多,对netty表示尊敬,以及getty本身借鉴了netty的设计思想。

然后作者本人姓氏的拼音首字符是“G”,因而取名getty。

说说写这个框架的原因:

1、作者本人是一名程序员,平时喜欢写写代码,特别是网络通讯方面。

2、JDK1.7升级了NIO类库,升级后的NIO类库被称为NIO 2.0。正式提供了异步文件I/O操作,同时提供了与UNIX网络编程事件驱动I/O对应的AIO。AIO的发布使得实现一套网络通讯框架变得相对简单。

3、本人对netty比较喜欢,无论是其性能还是编程思想(JBOSS提供的一个java开源网络框架,可以说是java网络通讯里的一哥,极其稳定和强大的性能使得被广泛使用)

4、有了netty为何还要自己造轮子?这里有两个原因,其一是本人喜欢造轮子,这是病,改不了。其二,netty经过多年的发展,其生态体系已经比较庞大,导致其代码比较臃肿,再者其高深的设计哲学我等凡夫俗子很难悟其精髓。因而索性造一个。

5、netty毕竟是国外的框架。并且国内也有许多优秀的开源框架,想想,为何不能自己也写一个呢?于是业余时间写了getty。

getty的特点:

1、完全基于java nio,基于nio1以及nio2(aio)做了实现,整体代码代码结构很轻量,也非常简单易用。

2、借鉴了netty和其他框架的部分优秀设计思想,如责任链、内存池化、零拷贝等优秀的设计模式。

3、getty提供了常用的多个插件(String编解码器,protobuf编解码器器,心跳超时处理器、ip过滤,websocket插件等)满足大部分开发场景。

4、getty可直接在安卓环境中使用(兼容Android5.0以上版本)

5、getty同时提供了TCP和UDP的支持,并且使用方式几乎一致,大大提高了易用性。

5、getty内置处理器支持使用过程中的热拔插设计,各处理器可以灵活组合。

6、框架拥有非常好的拓展性,处理器拓展也非常简单,大大降低了开发成本。

7、高效和稳定性能,经过多次测试,同时发送百万消息的耗时居然比netty还好。

相同的条件下发送百万条消息,getty 使用nio2模式耗时500毫秒左右,使用nio1模式耗时1.5秒左右,netty耗时2.5秒左右(也许是netty里面做了很多其他处理)。

8、使用过程与netty非常相似,只要有netty是使用经验,使用getty几乎不需要额外学习。

简单使用

Maven

在项目的pom.xml的dependencies中加入以下内容:

        <dependency>
            <groupId>com.gettyio</groupId>
            <artifactId>getty-core</artifactId>
            <version>1.3.1</version>
        </dependency>

Gradle

compile group: 'com.gettyio', name: 'getty-core', version: '1.3.1'

非Maven项目

可直接到中央仓库下载jar包导入到工程中

新版本特征

部分朋友希望对1.7版本兼容,特别是低Android版本,比如Android 5.0的兼容,因此新版本做了这块的更新

1、添加 nio 1支持

2、去除必须jdk1.8的特征,对JDK1.7做了版本兼容

3、对openjdk7版本兼容

4、对Android5.0版本兼容

优化

优化了部分代码,提高了稳定性
