jedis处理redis cluster集群的密码问题

环境介绍:jedis:2.8.0

redis版本:3.2

首先说一下redis集群的方式,一种是cluster的 一种是sentinel的,cluster的是redis 3.0之后出来新的集群方式

本身redis3.2的cluster集群是支持密码的 ,具体怎么搭建,可以查找相关的文档,这里只介绍应用层面的操作

 

jedis2.8.0的版本没有实现对redis cluster集群的密码操作

在jedis中创建redis cluster的对象时,一般是采用

JedisCluster jedisCluster = new JedisCluster(clusterNodes,timeout,jedisPoolConfig);

我们在项目中直接写了一个类专门来负责操作redis的

public class RedisClusterUtil {
    private static final Logger LOGGER = Logger.getLogger(RedisClusterUtil.class);
    private int timeout = 10000;
    private JedisCluster jedisCluster;
    private Set<HostAndPort> clusterNodes ;

    public RedisClusterUtil(String redisUris, JedisPoolConfig jedisPoolConfig) throws  Exception{
        init(redisUris);
        checkHostAndPost();
        jedisCluster = new JedisCluster(clusterNodes,timeout,jedisPoolConfig);
    }
    
    /**
     * reids 链接节点地址
     */
    public void init(String redisUris) {
        LOGGER.info("redisUris:" + redisUris);
        // ## 注册redis连接节点
        clusterNodes = Sets.newHashSet();
        if(StringUtils.isNotBlank(redisUris)){
            // 以“;”分割成"ip:post"
            String [] ipAndPostes = redisUris.split(";");
            // 以“:”分割成 “ip”,“post”
            if(ipAndPostes != null){
                for (String ipAndPost : ipAndPostes){
                    //ipAndPost 值:(ip:端口)
                    String [] ipAndPostArray = ipAndPost.split(":");
                    clusterNodes.add(new HostAndPort(ipAndPostArray[0], Integer.parseInt(ipAndPostArray[1])));
                }
            }
        }
        LOGGER.info("redis链接节点个数(clusterNodes):" + clusterNodes.size());
    }

  我们创建好jedisCluster之后,看了一下jedisCluster里面有一个jedisCluster.auth("密码")方法,可惜,这个方法里面什么都没有实现,仅仅抛一个异常

  @Deprecated

  @Override

  public String auth(String password) {

    throw new JedisClusterException("No way to dispatch this command to Redis Cluster.");

 

  }

所以想通过这个来设置密码是没戏啦,只能去修改jedis的源码啦,我们先直接启动一下看下报错信息,会发现整个jedis在操作cluster集群涉及到的主要的类

这里我们会发现cluster集群最终会调用redis.clients.jedis.JedisClusterConnectionHandler.initializeSlotsCache(Set<HostAndPort>, GenericObjectPoolConfig)方法,而这个方法里面的代码是

 

  private void initializeSlotsCache(Set<HostAndPort> startNodes, GenericObjectPoolConfig poolConfig) {
    for (HostAndPort hostAndPort : startNodes) {
      Jedis jedis = new Jedis(hostAndPort.getHost(), hostAndPort.getPort());
      try {
        cache.discoverClusterNodesAndSlots(jedis);
        break;
      } catch (JedisConnectionException e) {
        // try next nodes
      } finally {
        if (jedis != null) {
          jedis.close();
        }
      }
    }

    for (HostAndPort node : startNodes) {
      cache.setNodeIfNotExist(node);
    }
  }

 

  这里我们可以看到代码中有jedis的创建,而jedis本身是可以支持password配置的,这样我们就可以直接写一个方法去给这个类中塞一个密码进去啦

以下是我自己添加的一个方法,主要是添加了密码  
private void initializeSlotsCache(Set<HostAndPort> startNodes, GenericObjectPoolConfig poolConfig,String password) { for (HostAndPort hostAndPort : startNodes) { Jedis jedis = new Jedis(hostAndPort.getHost(), hostAndPort.getPort()); jedis.auth(password); try { cache.discoverClusterNodesAndSlots(jedis); break; } catch (JedisConnectionException e) { // try next nodes } finally { if (jedis != null) { jedis.close(); } } } for (HostAndPort node : startNodes) { cache.setNodeIfNotExist(node); } }

这样我们就让JedisClusterConnectionHandler支持了密码,再根据上面的异常信息中的信息,分别去新增方法去传递password到JedisClusterConnectionHandler;这里就部再详细介绍每段代码啦,从异常信息中就知道要修改哪些方法啦

重写的jedis的代码如上,重写了jedis的4个类,4个类中分别新增了一个方法,最新项目中调用时,就可以

直接

    public RedisClusterUtil(String redisUris, JedisPoolConfig jedisPoolConfig) throws  Exception{

        init(redisUris);

        checkHostAndPost();

        jedisCluster = new JedisCluster(clusterNodes,timeout,jedisPoolConfig,"密码");

 

    }

 

这样就结束啦

public class RedisClusterUtil {    private static final Logger LOGGER = Logger.getLogger(RedisClusterUtil.class);    private int timeout = 10000;    private JedisCluster jedisCluster;    private Set<HostAndPort> clusterNodes ;
    public RedisClusterUtil(String redisUris, JedisPoolConfig jedisPoolConfig) throws  Exception{        init(redisUris);        checkHostAndPost();        jedisCluster = new JedisCluster(clusterNodes,timeout,jedisPoolConfig,"!QAZ2wsx");    }        /**     * reids 链接节点地址     */    public void init(String redisUris) {        LOGGER.info("redisUris:" + redisUris);        // ## 注册redis连接节点        clusterNodes = Sets.newHashSet();        if(StringUtils.isNotBlank(redisUris)){            // 以“;”分割成"ip:post"            String [] ipAndPostes = redisUris.split(";");            // 以“:”分割成 “ip”,“post”            if(ipAndPostes != null){                for (String ipAndPost : ipAndPostes){                    //ipAndPost 值:(ip:端口)                    String [] ipAndPostArray = ipAndPost.split(":");                    clusterNodes.add(new HostAndPort(ipAndPostArray[0], Integer.parseInt(ipAndPostArray[1])));                }            }        }        LOGGER.info("redis链接节点个数(clusterNodes):" + clusterNodes.size());    }
