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*$");@Overridepublic JedisCluster getObject() throws Exception {return jedisCluster;}@Overridepublic Class<? extends JedisCluster> getObjectType() {return (this.jedisCluster != null ? this.jedisCluster.getClass() : JedisCluster.class);}@Overridepublic 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);}}@Overridepublic 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

@Autowiredprivate JedisCluster jedisCluster;
