spring集成 JedisCluster 连接 redis3.0 集群

原文：http://xyqck163.iteye.com/blog/2211108

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

 

  <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=172.16.23.27:6379
address2=172.16.23.27:6380
address3=172.16.23.27:6381
address4=172.16.23.27:6382
address5=172.16.23.27:6383
address6=172.16.23.27:6384




4.增加java类



package cn.zsmy.palmdoctor.redis;

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 String password;

    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);
        jedisCluster = new JedisCluster(haps, timeout, 2000, maxRedirections, password, 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;
    }

    public void setPassword(String password) {
        this.password = password;
    }

}

5.到此配置完成

使用时，直接注入即可， 如下所示：

@Autowired

JedisCluster jedisCluster;
