我在使用带有 Jedis 连接池的 Redis 时遇到问题。
我看到的行为是,在建立连接后,它们不会被释放回连接池。
我知道这一点是因为使用 redis-cli client list
命令我可以看到连接仍然存在。
有人可以检查我的 jedis 连接池,让我知道这是否会导致问题。
<spring:bean id="ElasticachePoolConfig" name="ElasticachePoolConfig" class="redis.clients.jedis.JedisPoolConfig" >
<!-- Minimum number of idle connections to Redis - these can be seen as always open and ready to serve -->
<spring:property name="minIdle" value="${redis.minIdle}" />
<!-- Number of connections to Redis that just sit there and do nothing -->
<spring:property name="maxIdle" value="${redis.maxIdle}" />
<!-- Maximum number of active connections that can be allocated from this pool at the same time -->
<spring:property name="maxTotal" value="${redis.maxTotal}" />
<!-- The minimum amount of time an object may sit idle in the pool before it is eligable for eviction by the idle object evictor.-->
<spring:property name="minEvictableIdleTimeMillis" value="${redis.minEvictableIdleTimeMillis}" />
<!-- The minimum amount of time a connection may sit idle in the pool before it is eligible for eviction by the idle connection evictor -->
<spring:property name="softMinEvictableIdleTimeMillis" value="${redis.softMinEvictableIdleTimeMillis}" />
<!-- The maximum number of milliseconds that the pool will wait (when there are no available connections) for a connection to be returned before throwing an exception -->
<spring:property name="maxWaitMillis" value="${redis.maxWaitMillis}" />
<!-- Maximum number of connections to test in each idle check -->
<spring:property name="numTestsPerEvictionRun" value="${redis.numTestsPerEvictionRun}" />
<!-- Tests whether connection is dead when connection retrieval method is called -->
<spring:property name="testOnBorrow" value="${redis.testOnBorrow}" />
<!-- Tests whether connection is dead when returning a connection to the pool -->
<spring:property name="testOnReturn" value="${redis.testOnReturn}" />
<!-- Tests whether connections are dead during idle periods -->
<spring:property name="testWhileIdle" value="${redis.testWhileIdle}" />
<!-- Idle connection checking period -->
<spring:property name="timeBetweenEvictionRunsMillis" value="${redis.timeBetweenEvictionRunsMillis}" />
<spring:property name="blockWhenExhausted" value="${redis.blockWhenExhausted}" />
</spring:bean>
其中属性设置如下...
redis.port=6379
redis.timeout=2000
redis.ttl=600
redis.host=localhost
redis.repeater.maxRetries=3
redis.repeater.millisBetweenRetries=2000
redis.minIdle=5
redis.maxIdle=10
redis.maxTotal=8
redis.minEvictableIdleTimeMillis=30000
redis.softMinEvictableIdleTimeMillis=-1
redis.maxWaitMillis=5000
redis.numTestsPerEvictionRun=10
redis.testOnBorrow=true
redis.testOnReturn=true
redis.testWhileIdle=false
redis.timeBetweenEvictionRunsMillis=50000
redis.blockWhenExhausted=true
最佳答案
您的 maxIdle
设置大于您的 maxTotal
设置,因此实际上不会在空闲时释放任何连接。该池将维护 maxIdle
连接。
JedisPool 在内部使用 Apache Commons Pooling。参见 this answer关于 maxIdle
和 maxTotal
之间的区别。
关于redis - Jedis 连接未被释放,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/46032586/
