连接到Redis

Jedis连接

简单连接示例

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">  <!-- Jedis ConnectionFactory -->  <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"/></beans>

生成环境示例，设置主机名、端口、密码和连接池

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">    <property name="maxTotal" value="50" />    <property name="maxIdle" value="50" />    <property name="minIdle" value="10" />    <property name="maxWaitMillis" value="15000" />    <property name="minEvictableIdleTimeMillis" value="60000" />    <property name="numTestsPerEvictionRun" value="-1" />    <property name="timeBetweenEvictionRunsMillis " value="30000" />    <property name="testOnBorrow" value="false" />    <property name="testOnReturn" value="false" />    <property name="testWhileIdle" value="true" /></bean><bean id="jedisConnectionFactory"    class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"    p:host-name="${redis.host}" p:port="${redis.port}" p:password="${redis.pass}"    p:poolConfig-ref="jedisPoolConfig" />

Lettuce连接

连接示例

<?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"  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">  <bean id="lettuceConnectionFactory" class="org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory" p:host-name="server" p:port="6379"/></beans>

默认，LettuceConnectionFactory创建的LettuceConnection共享同一个线程安全的本地连接处理非阻塞和非事物的操作。将shareNativeConnection 设置为 false可以让LettuceConnectionFactory每次创建一个专用连接。

LettuceConnectionFactory可通过LettucePool 属性配置连接池用于非阻塞和非事物操作，在shareNativeConnection 设置为 false时将用于所有操作。

Redis Sentinel（哨兵）支持

/** * jedis */@Beanpublic RedisConnectionFactory jedisConnectionFactory() {  RedisSentinelConfiguration sentinelConfig = new RedisSentinelConfiguration() .master("mymaster")  .sentinel("127.0.0.1", 26379) .sentinel("127.0.0.1", 26380);  return new JedisConnectionFactory(sentinelConfig);}/** * lettuce */@Beanpublic RedisConnectionFactory lettuceConnectionFactory() {  RedisSentinelConfiguration sentinelConfig = new RedisSentinelConfiguration().master("mymaster")  .sentinel("127.0.0.1", 26379) .sentinel("127.0.0.1", 26380);  return new LettuceConnectionFactory(sentinelConfig);}

使用配置文件配置时可使用以下属性
- spring.redis.sentinel.master: master节点名称
- spring.redis.sentinel.nodes:逗号分隔的host:port对.
