com.xxl.job.admin.core.route.ExecutorRouter

com.xxl.job.admin.core.route.strategy.ExecutorRouteConsistentHash

public class ExecutorRouteConsistentHash
extends ExecutorRouter

分组下机器地址相同，不同JOB均匀散列在不同机器上，保证分组下机器分配JOB平均；且每个JOB固定调度其中一台机器； a、virtual node：解决不均衡问题 b、hash method replace hashCode：String的hashCode可能重复，需要进一步扩大hashCode的取值范围 Created by xuxueli on 17/3/10.
