distributed-tool

项目介绍

这是一个分布式常用工具组件。其中包括但不限于:
分布式List、分布式Set、分布式Long、分布式信号量、分布式缓存、分布式锁、分布式序列号生成器、分布式订阅发布模式等常用工具类
目前微服务开发的系统很多,这个就涉及到分布式集群问题。像以前如果是单机,那么这些解决方案都可以使用JVM的API来实现
但在分布式环境下,这些API都不可用,所以急需一套分布式的API来支持这种常用操作,那么我来提供了,后面持续添加各种分布式常用工具类
注意:所有组件目前都是线程不安全,如果多线程请使用多实例,或者自己加同步锁

软件架构

目前项目分两个module,distributed-tool和distributed-tool-test。前者是核心源码。后者是测试代码。
distributed-tool主要分如下模块:分布式List、分布式Set、分布式Long、分布式信号量等

  1. core 提供基本分布式组件。(V1.3支持)
  2. cache 简单的分布式缓存模块。(V1.3支持)
  3. lock 分布式锁。(V1.3支持)
  4. pubsub 分布式订阅发布组件。(V1.3支持)
  5. sequence 分布式序列号生成器。(V1.3支持)

版本更新

V1.0版本
  • 新增client模块(所有工具组件的核心)
  • 新增cache模块(分布式缓存工具)
  • 新增sequence模块(分布式序列号生成工具)
V1.1版本
  • 新增pubsub模块(订阅发布模块)
V1.2版本
  • 新增queue模块(分布式队列)
  • 重构底层DtClient模块,该模块线程不安全,如果多线程操作,需要自己同步锁,或者新建不同实例
  • 新增全局单例Dt类,初始化一次后,后面使用各组件不用在设置DtClient的工厂类
V1.3版本
  • 重构底层实现,时用户使用更加的方便
  • 新增分布式锁
  • 新增分布式信号量
V1.4版本
  • 支持Redis的主备模式+哨兵部署

使用教程

初始化(目前底层使用了Redis来实现,所以使用Redis方式初始化)


Dt.getInstance().initJedis("xxx", 8380, "xxx");

销毁(注意,在应用的结束生命周期上加上销毁代码,例如Spring的destroy周期)


Dt.getInstance().getDefaultJedisFactory().destroy();

一个分布式List使用例子


DtList list = Dt.newDtList("listName");
list.pushLeft(new String[] { "a", "b" });
list.popLeft();
list.close();//使用完毕记得close

一个分布式缓存锁使用例子


DtLock lock = Dt.newDtLock("lockName");
String kId = lock.tryLock();
//你的临界资源操作逻辑
lock.unLock(kId);
lock.close();//使用完毕记得close
