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。
