Spring + JedisCluster操作Redis（集群）

1.maven依赖：

  
    redis.clients  
    jedis  
    2.7.3  
  

2.增加spring 配置

  
  
      
      
      
      
  
  
      
           classpath:redis-nodes.properties  
         
         
         
          
         
         
         
  

3.增加connect-redis.properties 配置文件

这里配置了6个节点

address1=192.168.221.128:7000  
address2=192.168.221.128:7001  
address3=192.168.221.128:7002  
address4=192.168.221.129:7003  
address5=192.168.221.129:7004  
address6=192.168.221.129:7005  

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, 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 getObjectType() {  
        return (this.jedisCluster != null ? this.jedisCluster.getClass() : JedisCluster.class);  
    }  
    @Override  
    public boolean isSingleton() {  
        return true;  
    }  
    private Set parseHostAndPort() throws Exception {  
        try {  
            Properties prop = new Properties();  
            prop.load(this.addressConfig.getInputStream());  
            Set haps = new HashSet();  
            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 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：

@Autowired  
JedisCluster jedisCluster;
