spring集成jedis支持redis3.0集群

接着上一节，我们通过spring FactoryBean实现redis 3.0集群JedisCluster与spring集成。

引用依赖：

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。
