自己创建一个类JedisClusterFactory：

import java.util.HashSet;
import java.util.Iterator;
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*$");

    public JedisClusterFactory() {
    }

    public JedisCluster getObject() throws Exception {
        return this.jedisCluster;
    }

    public Class<? extends JedisCluster> getObjectType() {
        return this.jedisCluster != null?this.jedisCluster.getClass():JedisCluster.class;
    }

    public boolean isSingleton() {
        return true;
    }

    private Set<HostAndPort> parseHostAndPort() throws Exception {
        try {
            Properties ex = new Properties();
            ex.load(this.addressConfig.getInputStream());
            HashSet haps = new HashSet();
            Iterator i$ = ex.keySet().iterator();

            while(i$.hasNext()) {
                Object key = i$.next();
                if(((String)key).startsWith(this.addressKeyPrefix)) {
                    String val = (String)ex.get(key);
                    boolean isIpPort = this.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 var9) {
            throw var9;
        } catch (Exception var10) {
            throw new Exception("解析 jedis 配置文件失败", var10);
        }
    }

    public void afterPropertiesSet() throws Exception {
        Set haps = this.parseHostAndPort();
        this.jedisCluster = new JedisCluster(haps, this.timeout.intValue(), this.maxRedirections.intValue(), this.genericObjectPoolConfig);
    }

    public void setAddressConfig(Resource addressConfig) {
        this.addressConfig = addressConfig;
    }

    public void setTimeout(int timeout) {
        this.timeout = Integer.valueOf(timeout);
    }

    public void setMaxRedirections(int maxRedirections) {
        this.maxRedirections = Integer.valueOf(maxRedirections);
    }

    public void setAddressKeyPrefix(String addressKeyPrefix) {
        this.addressKeyPrefix = addressKeyPrefix;
    }

    public void setGenericObjectPoolConfig(GenericObjectPoolConfig genericObjectPoolConfig) {
        this.genericObjectPoolConfig = genericObjectPoolConfig;
    }
}

redis-config.properties：

address1=192.168.1.36:6379
address2=192.168.1.37:6379
address3=192.168.1.38:6379
address4=192.168.1.40:6379
address5=192.168.1.41:6379
address6=192.168.1.42:6379

Java调用：

@Autowired
private JedisCluster jedisCluster;　　//jedisCluster就是对应的bean id 可以自动注入

System.out.println(jedisCluster.get("foo"));
System.out.println(jedisCluster.set("qq","222"));
System.out.println(jedisCluster.get("qq"));
