客户端采用最新的jedis 2.7

1.maven依赖：

<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.7.3</version>
</dependency>

2.增加spring 配置

<bean name="genericObjectPoolConfig" class="org.apache.commons.pool2.impl.GenericObjectPoolConfig" >
			<property name="maxWaitMillis" value="-1" />
			<property name="maxTotal" value="1000" />
			<property name="minIdle" value="8" />
			<property name="maxIdle" value="100" />
	</bean>

	<bean id="jedisCluster" class="xxx.JedisClusterFactory">
		<property name="addressConfig">
			<value>classpath:connect-redis.properties</value>
		</property>
		<property name="addressKeyPrefix" value="address" />  <!-- 属性文件里 key的前缀 -->
		
		<property name="timeout" value="300000" />
		<property name="maxRedirections" value="6" />
		<property name="genericObjectPoolConfig" ref="genericObjectPoolConfig" />
	</bean>

3.增加connect-redis.properties 配置文件

这里配置了6个节点

address1=*:*
address2=*:*
address3=*:*
address4=*:*
address5=*:*
address6=*:*

4.增加java类：

import java.util.HashSet;
import java.util.Properties;
import java.util.Set;
import java.util.regex.Pattern;
import org.apache.commons.pool2.impl.GenericObjectPoolConfig;
import org.springframework.beans.factory.FactoryBean;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.core.io.Resource;
import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.JedisCluster;
public class JedisClusterFactory implements FactoryBean<JedisCluster>, InitializingBean {
	private Resource addressConfig;
	private String addressKeyPrefix ;
	private JedisCluster jedisCluster;
	private Integer timeout;
	private Integer maxRedirections;
	private GenericObjectPoolConfig genericObjectPoolConfig;
	private Pattern p = Pattern.compile("^.+[:]\\d{1,5}\\s*$");
	@Override
		public JedisCluster getObject() throws Exception {
		return jedisCluster;
	}
	@Override
		public Class<? extends JedisCluster> getObjectType() {
		return (this.jedisCluster != null ? this.jedisCluster.getClass() : JedisCluster.class);
	}
	@Override
		public Boolean isSingleton() {
		return true;
	}
	private Set<HostAndPort> parseHostAndPort() throws Exception {
		try {
			Properties prop = new Properties();
			prop.load(this.addressConfig.getInputStream());
			Set<HostAndPort> haps = new HashSet<HostAndPort>();
			for (Object key : prop.keySet()) {
				if (!((String) key).startsWith(addressKeyPrefix)) {
					continue;
				}
				String val = (String) prop.get(key);
				Boolean isIpPort = p.matcher(val).matches();
				if (!isIpPort) {
					throw new IllegalArgumentException("ip 或 port 不合法");
				}
				String[] ipAndPort = val.split(":");
				HostAndPort hap = new HostAndPort(ipAndPort[0], Integer.parseint(ipAndPort[1]));
				haps.add(hap);
			}
			return haps;
		}
		catch (IllegalArgumentException ex) {
			throw ex;
		}
		catch (Exception ex) {
			throw new Exception("解析 jedis 配置文件失败", ex);
		}
	}
	@Override
		public void afterPropertiesSet() throws Exception {
		Set<HostAndPort> haps = this.parseHostAndPort();
		jedisCluster = new JedisCluster(haps, timeout, maxRedirections,genericObjectPoolConfig);
	}
	public void setAddressConfig(Resource addressConfig) {
		this.addressConfig = addressConfig;
	}
	public void setTimeout(int timeout) {
		this.timeout = timeout;
	}
	public void setMaxRedirections(int maxRedirections) {
		this.maxRedirections = maxRedirections;
	}
	public void setAddressKeyPrefix(String addressKeyPrefix) {
		this.addressKeyPrefix = addressKeyPrefix;
	}
	public void setGenericObjectPoolConfig(GenericObjectPoolConfig genericObjectPoolConfig) {
		this.genericObjectPoolConfig = genericObjectPoolConfig;
	}
}

5.到此配置完成

使用时，直接注入即可，如下所示：
