spring集成redis cluster详解

客户端采用最新的jedis 2.7

1.maven依赖：

redis.clients

jedis

2.7.3

2.增加spring 配置

classpath:connect-redis.properties

3.增加connect-redis.properties 配置文件

这里配置了6个节点

address1=*:*

address2=*:*

address3=*:*

address4=*:*

address5=*:*

address6=*:*

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 extends JedisCluster> 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.addrehttp://ssConfig = 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;
