问题：

Spring和Redis的"无法将资源返回到池"错误

井轶
2023-03-14

我试图用基于XML的配置用Spring实现Redis。我的配置文件如下所示：

<!-- 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;
}

当我第一次点击这个函数时，我得到了如下所述的错误。当我第二次尝试时，它工作正常并存储在Redis中。

有人知道我该如何修复这个错误吗？

正如@mp911de在这里提到的，这个问题与Spring Data Redis版本有关。当我升级时，问题解决了。

虽然我看不到你的代码，但我看到过当你两次试图关闭绝地实例时会发生这种情况，而没有注意到。例如：绝地实现了可关闭，当使用资源进行尝试时，它将自动关闭。

try(Jedis jedis = getJedis()){

}catch{...}

所以如果你也叫绝地武士。close（）它将抛出该错误。

任何一个

try{
    Jedis jedis = getJedis();
}catch(){
}finally{
    jedis.close()
}

或者查看是否多次调用close（）
