redis学习笔记——单机搭建redis

不这里只是个人的redis使用笔记，对redis就不多做介绍了，直接开启传送门
菜鸟教程：http://www.runoob.com/redis/redis-install.html
按照提示就可以安装并启动成功,由于windows版本没有后台启动设置,所以

这个最好还是不要关掉。

那么既然redis安装成功了,接下来就干正事。首先包不能少：
jedis.2.4.1jar : http://download.csdn.net/download/viena/8143821
commons-pool2-2.0.jar : http://download.csdn.net/download/f765961322/7357681
spring-data-redis1.3.4.RELEASE.jar :
http://mvnrepository.com/artifact/org.springframework.data/spring-data-redis/1.3.4.RELEASE
以上传送若失效,请另寻资源.

接下来在java中配置:
1.配置文件:properties(当然也可以写在xml文件中,但单独配置以后方便修改)

#与redis.windows.conf中bind对应的ip,默认为127.0.0.1
redis.host=127.0.0.1
#与redis.windows.conf中port对应的端口,默认为6379
redis.port=6379
redis.pool.maxTotal=300
redis.pool.maxIdle=20
redis.pool.minIdle=5
redis.pool.testOnBorrow=true
redis.timeout=15000
redis.usePool=true

2.spring-redis.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: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">    
    
    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxTotal" value="${redis.pool.maxTotal}" />
        <property name="maxIdle" value="${redis.pool.maxIdle}" />
        <property name="minIdle" value="${redis.pool.minIdle}" />
        <property name="testOnBorrow" value="${redis.pool.testOnBorrow}" />
    bean>
    <bean id="jedisConnectionFactory"
        class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="hostName" value="${redis.host}" />
        <property name="port" value="${redis.port}" />
        <property name="timeout" value="${redis.timeout}" />
        <property name="usePool" value="${redis.usePool}" />
        <property name="poolConfig" ref="jedisPoolConfig" />
    bean>
    <bean id="stringRedisSerializer"
        class="org.springframework.data.redis.serializer.StringRedisSerializer" />
    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="jedisConnectionFactory"/>
        <property name="keySerializer" ref="stringRedisSerializer"/>
        <property name="hashKeySerializer" ref="stringRedisSerializer"/>
    bean> 
beans>

3.spring的配置文件中,加入以下代码(redis.properties放在工作目录下)

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location">
            <value>classpath:redis.propertiesvalue>
        property>
        <property name="fileEncoding" value="utf-8" />
    bean>
    <import resource="spring-redis.xml"/>

4.redis操作工具类(百度有很多,如果不能满足要求可以另外找)

5.简单的测试写入及获取缓存

    @Autowired
    public RedisUtil
