redis与spring集成--不使用spring-data-redis

来源：互联网发布：黑客帝国动画版知乎编辑：程序博客网时间：2024/05/17 01:48

个人感觉如果使用spring-data-redis只作为缓存的话有点累赘，所以有了以下方式

之前在网上搜索了一些资料，但是其中的配置总是报错，原因是JedisShardInfo类缺少相应的构造方法......

1.redis.xml配置

spring的配置文件

<?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:p="http://www.springframework.org/schema/p"      xmlns:context="http://www.springframework.org/schema/context"      xmlns:jee="http://www.springframework.org/schema/jee"     xmlns:tx="http://www.springframework.org/schema/tx"      xmlns:aop="http://www.springframework.org/schema/aop"      xsi:schemaLocation="              http://www.springframework.org/schema/beans             http://www.springframework.org/schema/beans/spring-beans.xsd              http://www.springframework.org/schema/context             http://www.springframework.org/schema/context/spring-context.xsd">      <context:property-placeholder location="classpath:redis.properties" />      <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">        <property name="maxIdle" value="${redis.maxIdle}" /><property name="maxWaitMillis" value="${redis.maxWait}" /><property name="testOnBorrow" value="${redis.testOnBorrow}" />    </bean>        <bean id="shardedJedisPool" class="redis.clients.jedis.ShardedJedisPool"  scope="singleton">        <constructor-arg index="0" ref="jedisPoolConfig" />        <constructor-arg index="1">            <list>                <bean class="redis.clients.jedis.JedisShardInfo">                <constructor-arg name="host" value="http://redis:${redis.password}@${redis.host}:${redis.port}"></constructor-arg>                </bean>            </list>        </constructor-arg>    </bean>        <bean id="data" class="com.x.redis.RedisDataSource">    <property name="shardedJedisPool" ref="shardedJedisPool"></property>    </bean>    </beans>

       <constructor-arg index="1">            <list>                <bean class="redis.clients.jedis.JedisShardInfo">                    <!-- 这里的http://redis:并不是固定的，只是为了传递参数 -->                     <constructor-arg name="host" value="http://redis:${redis.password}@${redis.host}:${redis.port}"></constructor-arg>                </bean>            </list>        </constructor-arg>

redis.properties配置

#redis configredis.host=127.0.0.1redis.port=6379redis.password=redisredis.maxIdle=100 redis.maxWait=1000 redis.testOnBorrow=true redis.timeout=100000

2.redisDatasource类

为了获取客户端实例方便

import redis.clients.jedis.ShardedJedis;import redis.clients.jedis.ShardedJedisPool;public class RedisDataSource{private ShardedJedisPool shardedJedisPool;/** * spring注入shardedJedisPool * @param shardedJedisPool */public void setShardedJedisPool(ShardedJedisPool shardedJedisPool){this.shardedJedisPool = shardedJedisPool;}/** * 获取redis客户端ShardedJedis对象 * @return */public ShardedJedis getRedisClient(){try{return shardedJedisPool.getResource();} catch (Exception e){System.err.println("get resource error");}return null;}}

3.测试代码

import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import redis.clients.jedis.ShardedJedis;import com.vclouds.redis.RedisDataSource;public class Sdao{@Testpublic void test(){ApplicationContext app = new ClassPathXmlApplicationContext("classpath:redis.xml");System.out.println(app);ShardedJedis client = app.getBean("data",RedisDataSource.class).getRedisClient();System.out.println(client);client.set("aa", "aaaa");System.out.println(client.get("aa"));}}

4.常见问题

1）.代码运行时要保证redis的服务器是启动状态，否则无法连接
2）.以上注入方式参考JedisShardInfo类源码
3）.个人感觉以上方式使用起来会便捷一些，但是如果将redis作为一个nosql数据库的话，这种方式不推荐
