我正在使用生菜连接到Redis:spring-boot-starter-redis:2.0.6.RELEASE,当我启动应用程序时,它会出现此错误:
[ERROR][main][ResourceLeakDetector][error] - LEAK:
HashedWheelTimer.release() was not called before it's garbage-
collected. See http://netty.io/wiki/reference-counted-objects.html for

redis配置文件:

redisProperties) {

redisTemplate(LettuceConnectionFactory lettuceConnectionFactory) {
}
private RedisStandaloneConfiguration connection(RedisProperties

}
config yaml文件:

有人帮忙吗?
答案 0 :(得分:1)
当创建多个RedisClient
实例而不共享ClientResources
时,通常会发生这种类型的错误。
Spring Boot创建一个单例实例,因此任何其他实例都可能由您的代码或外部依赖项创建。没有更多的上下文,就不可能说更多。

如果您在应用程序中使用许多RedisClient
实例-您需要在它们之间共享ClientResources
对象。
创建RedisClient的典型方法是:
RedisClient.create("someUrl");
但是,当您要创建多个实例时,不建议使用这种对象创建方式。
在RedisClient
内部,有一个带有重物的区域:ClientResources
在创建RedisClient
的许多实例时,在运行时可能会产生错误
LEAK: You are creating too many HashedWheelTimer instances. HashedWheelTimer is a shared resource that must be reused across the JVM,so that only a few instances are created.
您可以做的是在您的应用程序中创建一个共享的ClientResources
。并将此对象传递给构造函数RedisClient
。
例如:
ClientResources sharedResources = DefaultClientResources.create();
//and use this between many RedisClients i.e.:
RedisClient first = RedisClient.create(sharedResources, "someUrl");
RedisClient second = RedisClient.create(sharedResources, "someUrl_222");
RedisClient third = RedisClient.create(sharedResources, "someUrl_3333");
