接着[上一节][Link 1]，我们通过spring FactoryBean实现redis 3.0集群JedisCluster与spring集成。

引用依赖：

<dependency>
    			<groupId>redis.clients</groupId>
    			<artifactId>jedis</artifactId>
    			<version>2.7.3</version>
    		</dependency>
    		<dependency>
    			<groupId>org.apache.commons</groupId>
    			<artifactId>commons-pool2</artifactId>
    			<version>2.4.2</version>
    		</dependency>
    		<dependency>
    			<groupId>org.springframework</groupId>
    			<artifactId>spring-context</artifactId>
    			<version>4.1.7.RELEASE</version>
    		</dependency>

java实现 JedisCluster的FactoryBean。

package cn.slimsmart.jediscluster.spring;
    
    import java.text.ParseException;
    import java.util.HashSet;
    import java.util.Set;
    
    import org.apache.commons.pool2.impl.GenericObjectPoolConfig;
    import org.springframework.beans.factory.FactoryBean;
    import org.springframework.beans.factory.InitializingBean;
    
    import redis.clients.jedis.HostAndPort;
    import redis.clients.jedis.JedisCluster;
    
    public class JedisClusterFactory implements FactoryBean<JedisCluster>, InitializingBean {
    
    	private GenericObjectPoolConfig genericObjectPoolConfig;
    	private JedisCluster jedisCluster;
    	private int connectionTimeout = 2000;
    	private int soTimeout = 3000;
    	private int maxRedirections = 5;
    	private Set<String> jedisClusterNodes;
    
    	@Override
    	public void afterPropertiesSet() throws Exception {
    		if (jedisClusterNodes == null || jedisClusterNodes.size() == 0) {
    			throw new NullPointerException("jedisClusterNodes is null.");
    		}
    		Set<HostAndPort> haps = new HashSet<HostAndPort>();
    		for (String node : jedisClusterNodes) {
    			String[] arr = node.split(":");
    			if (arr.length != 2) {
    				throw new ParseException("node address error !",node.length()-1);
    			}
    			haps.add(new HostAndPort(arr[0], Integer.valueOf(arr[1])));
    		}
    		jedisCluster = new JedisCluster(haps, connectionTimeout, soTimeout, maxRedirections, genericObjectPoolConfig);
    	}
    
    	@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;
    	}
    
    	public GenericObjectPoolConfig getGenericObjectPoolConfig() {
    		return genericObjectPoolConfig;
    	}
    
    	public void setGenericObjectPoolConfig(GenericObjectPoolConfig genericObjectPoolConfig) {
    		this.genericObjectPoolConfig = genericObjectPoolConfig;
    	}
    
    	public JedisCluster getJedisCluster() {
    		return jedisCluster;
    	}
    
    	public void setJedisCluster(JedisCluster jedisCluster) {
    		this.jedisCluster = jedisCluster;
    	}
    
    	public int getConnectionTimeout() {
    		return connectionTimeout;
    	}
    
    	public void setConnectionTimeout(int connectionTimeout) {
    		this.connectionTimeout = connectionTimeout;
    	}
    
    	public int getSoTimeout() {
    		return soTimeout;
    	}
    
    	public void setSoTimeout(int soTimeout) {
    		this.soTimeout = soTimeout;
    	}
    
    	public int getMaxRedirections() {
    		return maxRedirections;
    	}
    
    	public void setMaxRedirections(int maxRedirections) {
    		this.maxRedirections = maxRedirections;
    	}
    
    	public Set<String> getJedisClusterNodes() {
    		return jedisClusterNodes;
    	}
    
    	public void setJedisClusterNodes(Set<String> jedisClusterNodes) {
    		this.jedisClusterNodes = jedisClusterNodes;
    	}
    }

spring配置使用JedisCluster

可以在应用中注入JedisCluster处理业务。
