acl权限如何在zookeeper中进行配置

    @Testpublic void testAclServer() {List<ACL> acls = new ArrayList<ACL>(2);try {Id id1 = new Id("digest", DigestAuthenticationProvider.generateDigest("fish:fishpw"));ACL acl1 = new ACL(ZooDefs.Perms.WRITE, id1);Id id2 = new Id("digest", DigestAuthenticationProvider.generateDigest("qsd:qsdpw"));ACL acl2 = new ACL(ZooDefs.Perms.READ, id2);acls.add(acl1);acls.add(acl2);// 所有用户都有权限// Id world = new Id("world", "anyone");// ACL worldAcl = new ACL(ZooDefs.Perms.READ, world);// acls.add(worldAcl);// 10.0.2.76是本机IP// Id id3 = new Id("ip", "10.0.2.76");// ACL acl3 = new ACL(ZooDefs.Perms.WRITE, id3);// acls.add(acl3);} catch (NoSuchAlgorithmException e1) {e1.printStackTrace();}ZooKeeper zk = null;try {zk = new ZooKeeper("10.0.1.75:2181,10.0.1.76:2181,10.0.1.77:2181", 300000, new Watcher() {// 监控所有被触发的事件public void process(WatchedEvent event) {System.out.println("已经触发了" + event.getType() + "事件！");}});if (zk.exists("/test", true) == null) {System.out.println(zk.create("/test", "ACL测试".getBytes(), acls, CreateMode.PERSISTENT));}} catch (IOException e) {e.printStackTrace();} catch (KeeperException e1) {e1.printStackTrace();} catch (InterruptedException e1) {e1.printStackTrace();}}@Testpublic void testAclClient() {try {ZooKeeper zk = new ZooKeeper("10.0.1.75:2181,10.0.1.76:2181,10.0.1.77:2181", 300000, new Watcher() {// 监控所有被触发的事件public void process(WatchedEvent event) {System.out.println("已经触发了" + event.getType() + "事件！");}});// 只有写权限zk.addAuthInfo("digest", "fish:fishpw".getBytes());// 只有读权限zk.addAuthInfo("digest", "qsd:qsdpw".getBytes());System.out.println(new String(zk.getData("/test", null, null)));zk.setData("/test", "I change！".getBytes(), -1);} catch (KeeperException e) {e.printStackTrace();} catch (InterruptedException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}
