我试图用基于XML的配置实现Redis with Spring。我的配置文件如下：
<!-- declare Redis Cache Manager -->
<bean id="cacheManager" class="org.springframework.data.redis.cache.RedisCacheManager"
c:template-ref="redisTemplate" />
<bean id="jedisConnectionFactory"
class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
p:host-name="172.17.0.2" p:use-pool="true" />
<!-- redis template definition -->
<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"
p:connection-factory-ref="jedisConnectionFactory" />
我的缓存定义如下：
@Cacheable(value = "my-cache-key", key = "{#argSomeObj, #argSomeString, #argSomeInt}")
public MyAwesomeDTO getSomeResult(SomeObject argSomeObj, String argSomeString, int argSomeInt, Request argRequest)
{
// this part calculates and returns some values regarding to given parameters
return awesomeDTO;
}
当我第一次点击此功能时出现下面所述的错误。当我第二次尝试时，它可以正常工作并存储在Redis中。

有谁知道我该如何解决这个错误？

虽然我无法看到您的代码，但是当您尝试关闭jedis实例两次而没有注意到时，我发现这种情况会发生。例如： Jedis实施Closable，当在try-with-Resources内时，它将自动关闭。
try(Jedis jedis = getJedis()){
}catch{...}
因此，如果你也调用jedis.close（），它将抛出该错误。
try{
Jedis jedis = getJedis();
}catch(){
}finally{
jedis.close()
}
或者查看您是否多次调用close（）

@ mp911de提到here，此问题与Spring Data Redis版本有关。当我升级时，它解决了。

这是基于java的配置。尝试并分享结果。
