## Redis 3.0集群搭建方法： ##

[http://hot66hot.iteye.com/blog/2050676][http_hot66hot.iteye.com_blog_2050676]

## Redis 3.0.x使用方法 ##

### 1.Maven依赖 ###

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.7.2</version>
    </dependency>

### 2.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" />     
          
        <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.增加实现的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.自动注入 ###

@Autowired private JedisCluster jedisCluster;

### １.Redis Sentinel模式 ###

Spring配置

<bean id="redisSentinelConfiguration" class="org.springframework.data.redis.connection.RedisSentinelConfiguration"> <constructor-arg name="master" value="${redis.master}"/> <constructor-arg name="sentinelHostAndPorts"> <set>     <value>${redis.sentinels}</value> </set> </constructor-arg> </bean> <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxIdle" value="${redis.maxIdle}" /> <property name="maxTotal" value="${redis.maxTotal}" /> <property name="testOnBorrow" value="${redis.testOnBorrow}" /> </bean> <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"> <constructor-arg name="sentinelConfig" ref="redisSentinelConfiguration"/> <constructor-arg name="poolConfig" ref="jedisPoolConfig"/> <property name="usePool" value="true"></property> <property name="password" value="${redis.password}" /> <property name="timeout" value="${redis.timeout}" /> <property name="database" value="${redis.db}" /> </bean> <bean id="stringRedisSerializer" class="org.springframework.data.redis.serializer.StringRedisSerializer" /> <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"> <property name="connectionFactory" ref="jedisConnectionFactory" /> <property name="defaultSerializer" ref="stringRedisSerializer" /> </bean> <bean id="cacheUtil" class="com.top.biz.util.RedisCacheUtil"> <property name="redisTemplate" ref="redisTemplate" /> </bean>

### ２.Redis单机配置 ###

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxIdle" value="${redis.maxIdle}" /> <property name="maxTotal" value="${redis.maxTotal}"></property> <property name="testOnBorrow" value="${redis.testOnBorrow}" /> </bean> <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"> <property name="usePool" value="true"></property> <property name="hostName" value="${redis.host}" /> <property name="port" value="${redis.port}" /> <property name="password" value="${redis.password}" /> <property name="timeout" value="${redis.timeout}" /> <property name="database" value="${redis.db}"></property> <property name="poolConfig" ref="jedisPoolConfig" /> </bean> <bean id="stringRedisSerializer" class="org.springframework.data.redis.serializer.StringRedisSerializer" /> <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"> <property name="connectionFactory" ref="jedisConnectionFactory" /> <property name="defaultSerializer" ref="stringRedisSerializer" /> </bean> <bean id="cacheUtil" class="com.top.biz.util.RedisCacheUtil"> <property name="redisTemplate" ref="redisTemplate" /> </bean>
