Distributed Synchronize 分布式同步组件

1. 分布式锁.
2. 基于Netty长连接实现.
3. 自定义协议,内置等待队列,性能远超redis锁.
4. 服务下线立刻感知,无需等待超时.
5. 支持优雅关闭.
6. 规避Redis分布式锁缺陷: http://zhangtielei.com/posts/blog-redlock-reasoning.html , http://zhangtielei.com/posts/blog-redlock-reasoning-part2.html

启动服务端

java -jar -server dsync-dominate-xxx.jar

启动jar可以在maven下载,或者下载源码 mvn package 获得.

分布式锁 DLock

1. 添加依赖

<dependency>
  <groupId>cn.cyejing</groupId>
  <artifactId>dsync-toolkit</artifactId>
</dependency>

2. 使用方法

Config config = Config.config().host("localhost").port(4843); //配置服务端地址
DSync dSync = DSync.create(config);
DLock lock = dSync.getLock();

try {
    lock.lock("adder");
    //Do Something
} finally {
    lock.unlock();
}
