Redis集群(3) 应用 spring集成

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";
}
