本文基于springmvc编写,实现spring使用redis集群的简单程序;
1.首先引用 redis.clients 依赖
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.7.3</version>
</dependency>
2. applicationContext.xml 添加
<import resource="redis.xml"/>
3. src/main/resources 下添加 redis.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd">
<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="com.hibernate.web.redis.JedisClusterFactory">
<property name="addressConfig">
<value>classpath:redis-nodes.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>
</beans>
文件中包括引入的 redis-nodes.properties 文件
address1=192.168.1.141:6380
address2=192.168.1.141:6381
address3=192.168.1.141:6382
address4=192.168.1.141:6383
address5=192.168.1.141:6384
address6=192.168.1.141:6385
4. 添加 JedisClusterFactory.java
package com.hibernate.web.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 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.创建 controller 使用 redis
@Autowired
private JedisCluster jedisCluster;
@ResponseBody
@RequestMapping(value = "/index")
public String index() {
jedisCluster.set("abc", "abcdefgs");
String getVal = jedisCluster.get("abc");
System.out.println("redisValue: " + getVal);
return "redis";
}
