Redis（四）：Spring + JedisCluster操作Redis（集群）

1.maven依赖：

<dependency>  <groupId>redis.clients</groupId>  <artifactId>jedis</artifactId>  <version>2.7.3</version>  
</dependency>

2.增加spring 配置

<!-- ==========================JedisCluster配置=========================== -->  
<bean name="genericObjectPoolConfig" class="org.apache.commons.pool2.impl.GenericObjectPoolConfig">  <property name="maxWaitMillis" value="-1"></property>  <property name="maxTotal" value="1000"></property>  <property name="minIdle" value="8"></property>  <property name="maxIdle" value="100"></property>  
</bean>  
<bean id="jedisCluster" class="com.atguigu.crud.util.JedisClusterFactory">  <property name="addressConfig">  <value>classpath:redis-nodes.properties</value>  </property>  <!-- 属性文件里 key的前缀 -->  <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=192.168.221.128:7000  
address2=192.168.221.128:7001  
address3=192.168.221.128:7002  
address4=192.168.221.129:7003  
address5=192.168.221.129:7004  
address6=192.168.221.129:7005

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;  }  
}
