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" />   <!--  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

<!-- Redis  Sentinel 集群配置 -->
<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>

Redis properties:

redis.master=mymaster
redis.sentinels=127.0.0.1:26379

redis.maxTotal=20
#redis.testOnBorrow=true
redis.testOnBorrow=false

<!-- 配置Redis方法  单机配置 -->
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">

<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="connectionFactory" ref="jedisConnectionFactory" />
<property name="defaultSerializer" ref="stringRedisSerializer" />
</bean>
<bean id="cacheUtil" class="com.top.biz.util.RedisCacheUtil">
<property name="redisTemplate" ref="redisTemplate" />
</bean>

<!--StringRedis Template  使用方法 -->
<!--
<bean id="stringRedisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
<property name="connectionFactory" ref="jedisConnectionFactory" />
</bean>
-->
<!--
@Resource(name='stringRedisTemplate')
private StringRedisTemplate redisTemplate;

redis.port=6379
redis.password=
redis.db=0
