# 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

```xml

  cn.cyejing

  dsync-toolkit

```

2. 使用方法

```java

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 {
