SSM整合Redis Cluster叢集緩存

1、pom引入依賴

<!--jedis連接配接redis叢集非常簡單，也可直接操作jedisCluster來增删改查資料庫。-->
    <dependency>
      <groupId>redis.clients</groupId>
      <artifactId>jedis</artifactId>
      <version>2.9.0</version>
    </dependency>

    <!-- spring-data-redis -->
    <dependency>
      <groupId>org.springframework.data</groupId>
      <artifactId>spring-data-redis</artifactId>
      <version>1.8.1.RELEASE</version>
    </dependency>

           

2、spring-redis.xml配置檔案

<?xml version="1.0" encoding="UTF-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xmlns:cache="http://www.springframework.org/schema/cache"
       xsi:schemaLocation="http://www.springframework.org/schema/beans

    <!-- 定義緩存管理器redisCacheManager。 注意：cache-manager預設值是cacheManager,你的緩存管理器id要是命名是cacheManager，這裡可以省略
        1.使用注解驅動 -->

    <!-- 2.定義緩存管理器 -->
    <bean id="redisCacheManager"
          class="org.springframework.data.redis.cache.RedisCacheManager">
        <!-- 通過構造方法注入redisTemplate -->

            <list>

            </list>
        </property>
    </bean>

</beans>

           

3、redis.properties配置

#redis
redis.pool.maxTotal=30
redis.pool.maxIdle=10
redis.pool.numTestsPerEvictionRun=1024
redis.pool.timeBetweenEvictionRunsMillis=30000
redis.pool.minEvictableIdleTimeMillis=1800000
redis.pool.softMinEvictableIdleTimeMillis=10000
redis.pool.maxWaitMillis=1500
redis.pool.testOnBorrow=true
redis.pool.testWhileIdle=true
redis.pool.blockWhenExhausted=false
redis.maxRedirects=3
redis.host1=192.168.189.100
redis.port1=7001
redis.host2=192.168.189.100
redis.port2=7002
redis.host3=192.168.189.100
redis.port3=7003
redis.host4=192.168.189.100
redis.port4=7004
redis.host5=192.168.189.100
redis.port5=7005
redis.host6=192.168.189.100
redis.port6=7006

           

這時已經配置好了，可以使用@Cacheable，@Cacheput,@CacheEvict等注解。

注意：

@CachePut(value = “redisCacheManager”,key = “‘blog_’+#articleId”)

value 的值隻可以是上面 redis 緩存管理器中 redis緩存器名稱的值，否則會報錯：未找到對應的緩存器名稱
