Java并发计数器LongAdder源码分析

1.数据结构 1.Node static class Node<K,V> implements Map.Entry<K,V> { final int hash; final K key; V value; Node<K,V> next; Node(int hash, K key, V value, Node<K,V> next) { this.hash = hash; this.key = key; this.value = va

1.LoadBalance 默认实现是RandomLoadBalance，对RegistryDirectory#list()出来的Invokers进行选择，然后发起访问 @SPI(RandomLoadBalance.NAME) public interface LoadBalance { @Adaptive("loadbalance") <T> Invoker<T> select(List<Invoker<T>> invoker
