这里利用zookeeper的EPHEMERAL_SEQUENTIAL类型节点及watcher机制,来简单实现分布式锁。
主要思想:
1、开启10个线程,在disLocks节点下各自创建名为sub的EPHEMERAL_SEQUENTIAL节点;
2、获取disLocks节点下所有子节点,排序,如果自己的节点编号最小,则获取锁;
3、否则watch排在自己前面的节点,监听到其删除后,进入第2步(重新检测排序是防止监听的节点发生连接失效,导致的节点删除情况);
4、删除自身sub节点,释放连接;
这里插播下zookeeper的4种节点类型:
- public enum CreateMode {
- /**
- * 持久节点:节点创建后,会一直存在,不会因客户端会话失效而删除;
- */
- PERSISTENT (0, false, false),
- /**
- * 持久顺序节点:基本特性与持久节点一致,创建节点的过程中,zookeeper会在其名字后自动追加一个单调增长的数字后缀,作为新的节点名;
- */
- PERSISTENT_SEQUENTIAL (2, false, true),
- /**
- * 临时节点:客户端会话失效或连接关闭后,该节点会被自动删除,且不能再临时节点下面创建子节点,否则报如下错:org.apache.zookeeper.KeeperException$NoChildrenForEphemeralsException;
- */
- EPHEMERAL (1, true, false),
- /**
- * 临时顺序节点:基本特性与临时节点一致,创建节点的过程中,zookeeper会在其名字后自动追加一个单调增长的数字后缀,作为新的节点名;
- */
- EPHEMERAL_SEQUENTIAL (3, true, true);
- private static final Logger LOG = LoggerFactory.getLogger(CreateMode.class);
- private boolean ephemeral;
- private boolean sequential;
- private int flag;
- CreateMode(int flag, boolean ephemeral, boolean sequential) {
- this.flag = flag;
- this.ephemeral = ephemeral;

- }
- public boolean isEphemeral() {

- case 1: return CreateMode.EPHEMERAL;
- case 2: return CreateMode.PERSISTENT_SEQUENTIAL;
- case 3: return CreateMode.EPHEMERAL_SEQUENTIAL ;
- default:
- LOG.error("Received an invalid flag value to convert to a CreateMode");
- throw new KeeperException.BadArgumentsException();
- }
- }
- }
