Spring Data Redis入门示例:程序配置（五）

单机配置

redis.properties配置

#redis的服务器地址
redis.host=127.0.0.1

#redis的服务端口
redis.port=6379

#客户端超时时间单位是毫秒
redis.timeout=100000

#最大建立连接等待时间
redis.maxWaitMillis=1000

#最小空闲数
redis.minIdle=5

#最大空闲数
redis.maxIdle=20

#最大连接数
redis.maxTotal=100

xml配置

<!-- 读取properties文件 -->
<bean id="propertyConfigurerForProject1"
      class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  <property name="order" value="1" />
  <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
  <property name="ignoreResourceNotFound" value="true" />
  <property name="ignoreUnresolvablePlaceholders" value="true" />
  <property name="locations">
    <list>
      <value>classpath*:redis.properties</value>
    </list>
  </property>
</bean>

<!-- Jedis连接池的配置对象 -->
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
	<!--最大空闲数 -->
	<property name="maxIdle" value="${redis.maxIdle}" />
	<!--最小空闲数 -->
	<property name="minIdle" value="${redis.minIdle}" />
	<!--最大连接数 -->
	<property name="maxTotal" value="${redis.maxTotal}" />
	<property name="testOnBorrow" value="true" />
	<!--最大建立连接等待时间 -->
	<property name="maxWaitMillis" value="${redis.maxWaitMillis}" />
</bean>

<!--jedis服务器信息 -->
<bean id="jedisShardInfo" class="redis.clients.jedis.JedisShardInfo">
	<constructor-arg index="0" value="${redis.host}" />
	<constructor-arg index="1" value="${redis.port}" type="int" />
	<constructor-arg index="2" value="${redis.timeout}"
		type="int" />
</bean>

<!--jedis连接池 -->
<bean id="shardedJedisPool" class="redis.clients.jedis.ShardedJedisPool">
	<constructor-arg index="0" ref="jedisPoolConfig" />
	<constructor-arg index="1">
		<list>
			<ref bean="jedisShardInfo" />
		</list>
	</constructor-arg>
</bean>

<!-- Redis连接工厂 -->
<bean id="jedisConnectionFactory"
	class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
	<property name="shardInfo" ref="jedisShardInfo" />
	<property name="poolConfig" ref="jedisPoolConfig" />
</bean>

<!-- 缓存序列化方式 -->
<!--对key的默认序列化器。默认值是StringSerializer -->
<bean id="keySerializer"
	class="org.springframework.data.redis.serializer.StringRedisSerializer" />

<!--是对value的默认序列化器，默认值是取自DefaultSerializer的JdkSerializationRedisSerializer。 -->
<bean id="valueSerializer"
	class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer" />

<!-- redis操作模板,对Jedis进行的通用API操作 -->
<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
	<property name="connectionFactory" ref="jedisConnectionFactory" />
	<property name="keySerializer" ref="keySerializer" />
	<property name="valueSerializer" ref="valueSerializer" />
	<property name="hashKeySerializer" ref="keySerializer" />
	<property name="hashValueSerializer" ref="valueSerializer" />
</bean>

自2.0开始，针对单机配置引入RedisStandaloneConfiguration 并且废弃了JedisConnectionFactory的HostName，Port，Password等属性的配置。

    /**
 * 连接工厂类
 * @return
 */
@Bean
public JedisConnectionFactory jedisConnectionFactory(){
	// 单机配置
	RedisStandaloneConfiguration standaloneConfig = new RedisStandaloneConfiguration();
	standaloneConfig.setHostName("127.0.01");
	standaloneConfig.setPort(6379);
	
	JedisConnectionFactory connectionFactory = new JedisConnectionFactory(standaloneConfig);
	
	return connectionFactory;
}

哨兵配置

为了处理高可用性的Redis，可以使用RedisSentinelConfiguration支持Redis Sentinel。

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

可以配置的属性：
spring.redis.sentinel.master：master节点的名字
spring.redis.sentinel.nodes：主机:端口的逗号分隔列表

集群配置

 @Bean
public JedisConnectionFactory redisConnectionFactory() {
   JedisConnectionFactory connectionFactory = new JedisConnectionFactory();
   // 集群配置
   RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration();
   RedisNode redisNode7000 = new RedisNode("10.1.21.4", 7000);
   RedisNode redisNode7001 = new RedisNode("10.1.21.4", 7001);
   RedisNode redisNode7002 = new RedisNode("10.1.21.4", 7002);
   RedisNode redisNode7003 = new RedisNode("10.1.21.4", 7003);
   RedisNode redisNode7004 = new RedisNode("10.1.21.4", 7004);
   RedisNode redisNode7005 = new RedisNode("10.1.21.4", 7005);

   redisClusterConfiguration.addClusterNode(redisNode7000);
   redisClusterConfiguration.addClusterNode(redisNode7001);
   redisClusterConfiguration.addClusterNode(redisNode7002);
   redisClusterConfiguration.addClusterNode(redisNode7003);
   redisClusterConfiguration.addClusterNode(redisNode7004);
   redisClusterConfiguration.addClusterNode(redisNode7005);
   connectionFactory = new JedisConnectionFactory(redisClusterConfiguration);

   // 设置连接池配置
   connectionFactory.setPoolConfig(jedisConfig());

   // 设置数据库，默认0
   connectionFactory.setDatabase(2);

   // 设置使用连接池
   connectionFactory.setUsePool(true);

   return connectionFactory;
}

配置说明

1. 以上配置是基于Jedis客户端的
2. 使用javaCode或者xml的配置方式依据个人喜好
