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 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, GenericObjectPoolConfig)方法，而这个方法里面的代码是

 

  private void initializeSlotsCache(Set 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 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

  • Spring Mybatis独立事务配置
                                    toknowme
mybatis
                                    
    在项目中有很多地方会使用到独立事务，下面以获取主键为例      
（1）修改配置文件spring-mybatis.xml    <!-- 开启事务支持 -->    <tx:annotation-driven transaction-manager="transactionManager" />       &n
