为zookeeper配置相应的acl权限

    @Test
	public 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);
