最近在公司做了 jedisCluster整合spring 的配置， 分享如下

 

客户端采用最新的jedis 2.7

1.

maven依赖：

<dependency>

<groupId>redis.clients</groupId>

<artifactId>jedis</artifactId>

<version>2.7.2</version>

</dependency>

 

2.

增加spring 配置（最好配置在application-context.xml，如果会用在shiro中的sessionDao时，必须要在加载shiro配置文件前加载此配置信息）

<bean name="genericObjectPoolConfig" class="org.apache.commons.pool2.impl.GenericObjectPoolConfig" >
<property name="maxWaitMillis" value="-1" />
<property name="maxTotal" value="1000" />
<property name="minIdle" value="8" />
<property name="maxIdle" value="100" />
</bean>

<bean id="jedisCluster" class="xxx.JedisClusterFactory">
<property name="addressConfig">
<value>classpath:connect-redis.properties</value>
</property>
<property name="addressKeyPrefix" value="address" /> <!-- 属性文件里 key的前缀 -->

<property name="timeout" value="300000" />
<property name="maxRedirections" value="6" />
<property name="genericObjectPoolConfig" ref="genericObjectPoolConfig" />
</bean>

 

3.

增加connect-redis.properties  配置文件

这里配置了6个节点

address1=192.168.1.249:7000
address2=192.168.1.249:7001
address3=192.168.1.249:7002
address4=192.168.1.248:7003
address5=192.168.1.248:7004
address6=192.168.1.248:7005

 

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<JedisCluster>, 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<HostAndPort> parseHostAndPort() throws Exception {
try {
Properties prop = new Properties();
prop.load(this.addressConfig.getInputStream());

Set<HostAndPort> haps = new HashSet<HostAndPort>();
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<HostAndPort> 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;

 

6.用法示例：

jedisCluster.set("aaa", "aaaaaa_value");
jedisCluster.expire("aaa", 100);

System.out.println(jedisCluster.get("aaa"));
