Spring MVC 集成 Redis集群
首先说一下我的包
commons-pool2-2.0.jar
jedis-2.7.2.jar
spring-data-redis-1.4.2.RELEASE.jar
tomcat-redis-session-manager1.2.jar
属性文件 redis.properties
属性文件 address1=127.0.0.1:7002 address2=127.0.0.1:7001 address3=127.0.0.1:7000 address4=127.0.0.1:7003 address5=127.0.0.1:7004 address6=127.0.0.1:7005
然后是配置文件 redis-context.xml
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd "> <!-- 连接池的配置 --> <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="jedisClusterFactory" class="com.hanwei.its.itoss.dao.redis.JedisClusterFactory"> <property name="addressConfig"> <value>classpath:conf/redis.properties</value> <value>/conf/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> </beans>
在 Spring MVC文件中引入redis 配置文件
<!-- 加载redis 配置文件 --> <import resource="redis-context.xml"/>
上代码

//实体类
package com.hanwei.its.itoss.model.redis;
import org.szopen.core.model.BaseModel;
public class Member extends BaseModel{
/**
*
*/
private static final long serialVersionUID = -1959528436584592183L;
private String id;
private String nickname;
private Object val;
private int index;
public Member(){}
public Member(String id, String nickname){
this.setId(id);
this.setNickname(nickname);
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getNickname() {
return nickname;
}
public void setNickname(String nickname) {
this.nickname = nickname;
}
public int getIndex() {
return index;
}
public void setIndex(int index) {
this.index = index;
}
public Object getVal() {
return val;
}
public void setVal(Object val) {
this.val = val;
}
}
剩下的就很无聊了
在dao层注入上面这个 Factory
需要注意的是 我这个 jedisClusterFactory 每次使用完毕都有执行close（）方法 使用前都要GET jedisClusterFactory.getObject(); 到新的对象
