Zookeeper Java client ACL permission usage

Zookeeper provides authority authentication as zookeeper client access restrictions, there are two main ways, 1, IP mode 2, digest permission mode

You can define permission content by creating a node. Here is the Java implementation

Package com.aicong.test.helloZookeeper;
Import java.io.IOException;
Import java.security.NoSuchAlgorithmException;

Import java.util.ArrayList;
Import Org.apache.zookeeper.CreateMode;
Import org.apache.zookeeper.KeeperException;
Import org.apache.zookeeper.WatchedEvent;
Import Org.apache.zookeeper.Watcher;
Import Org.apache.zookeeper.Watcher.Event.EventType;
Import Org.apache.zookeeper.Watcher.Event.KeeperState;
Import org.apache.zookeeper.ZooDefs.Perms;
Import Org.apache.zookeeper.ZooKeeper;
Import Org.apache.zookeeper.data.ACL;
Import Org.apache.zookeeper.data.Id;


Import Org.apache.zookeeper.server.auth.DigestAuthenticationProvider;
	public class Createnodesyncauth implements watcher {private static Zookeeper zookeeper;
	
	private static Boolean somethingdone = false; public static void Main (string[] args) throws IOException, interruptedexception {zookeeper = new zookeeper ("112.74.219.
		174:2181 ", 5000,new Createnodesyncauth ());
		
	System.out.println (Zookeeper.getstate ());	Thread.Sleep (Integer.max_value); /* * Permission mode (scheme): IP, Digest * Authorization Object (ID) * IP rights mode: specific IP address * Digest permission mode: Username:base64 (SHA-1 username: Password)) * Permission (permission): Create (C), DELETE (D), READ (R), WRITE (W), ADMIN (A) * Note: Individual permissions, full permissions, composite permissions * * Permission combination: Sch EME + ID + Permission * * * * * * * * */private void dosomething () {try {///Create node requires permission validation//ip-based ACL ACL
			ip = new ACL (perms.read,new Id ("IP", "112.74.219.174")); Based on username password ACL acldigest = new ACL (perms.read|
			Perms.write,new Id ("Digest", Digestauthenticationprovider.generatedigest ("jike:123456"));
			Arraylist<acl> ACLS = new arraylist<acl> ();
			Acls.add (acldigest);
			Acls.add (Aclip);			
			Zookeeper.addauthinfo ("Digest", "jike:123456". GetBytes ());
			String Path = zookeeper.create ("/node_10", "123". GetBytes (), ACLs, Createmode.persistent);
			
			System.out.println ("Return path:" +path);
			
		Somethingdone = true;
		catch (Keeperexception e) {e.printstacktrace (); } CAtch (interruptedexception e) {e.printstacktrace ();
		catch (NoSuchAlgorithmException e) {//TODO auto-generated catch block E.printstacktrace (); @Override public void Process (Watchedevent event) {//TODO auto-generated Method Stub System.out.println ("Received event
		: "+event); if (Event.getstate () ==keeperstate.syncconnected) {if (!somethingdone && event.gettype () ==eventtype.none
			&& Null==event.getpath ()) {dosomething ();
 }
		}
	}
	
}

Callers can use code:

Package com.aicong.test.helloZookeeper;

Import java.io.IOException;
Import org.apache.zookeeper.KeeperException;
Import org.apache.zookeeper.WatchedEvent;
Import Org.apache.zookeeper.Watcher;
Import Org.apache.zookeeper.Watcher.Event.EventType;
Import Org.apache.zookeeper.Watcher.Event.KeeperState;
Import Org.apache.zookeeper.ZooKeeper;


Import Org.apache.zookeeper.data.Stat;
    public class Getdatasyncauth implements watcher{private static zookeeper zookeeper;
    
	private static Stat Stat = new Stat (); public static void Main (string[] args) throws IOException, Interruptedexception, keeperexception {zookeeper = new Zo
		Okeeper ("112.74.219.174:2181", 5000,new Getdatasyncauth ());
	
		System.out.println (Zookeeper.getstate (). toString ());
		

	Thread.Sleep (Integer.max_value);
		
			} private void DoSomething (Zookeeper zookeeper) {//permission validation zookeeper.addauthinfo ("Digest", "jike:1234". GetBytes ()); try {System.out.println (Zookeeper.getdata ("/node_4", trUE, STAT));
			catch (Keeperexception e) {e.printstacktrace ();
			catch (Interruptedexception e) {e.printstacktrace (); @Override public void Process (Watchedevent event) {//TODO auto-generated method stub if Event.getstate ( ==keeperstate.syncconnected) {if (Event.gettype () ==eventtype.none && Null==event.getpath ()) {doSomething (Z
			Ookeeper); }else{if (Event.gettype () ==eventtype.nodedatachanged) {try {System.out.println (new String (ZOOKEEPER.G
						Etdata (Event.getpath (), True, stat));
					System.out.println ("stat:" +stat);
					catch (Keeperexception e) {e.printstacktrace ();
					catch (Interruptedexception e) {e.printstacktrace ();
 }
					
				}	
			}
		
		}
	}
