本文整理了Java中com.netflix.loadbalancer.ZoneAffinityServerListFilter类的一些代码示例，展示了ZoneAffinityServerListFilter类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ZoneAffinityServerListFilter类的具体详情如下：
包路径：com.netflix.loadbalancer.ZoneAffinityServerListFilter
类名称：ZoneAffinityServerListFilter

ZoneAffinityServerListFilter介绍

[英]This server list filter deals with filtering out servers based on the Zone affinity. This filtering will be turned on if either CommonClientConfigKey#EnableZoneAffinity or CommonClientConfigKey#EnableZoneExclusivity is set to true in IClientConfig object passed into this class during initialization. When turned on, servers outside the same zone (as indicated by Server#getZone()) will be filtered out. By default, zone affinity and exclusivity are turned off and nothing is filtered out.
[中]此服务器列表筛选器用于根据区域关联筛选出服务器。如果在初始化期间传递到此类的IClientConfig对象中将CommonClientConfigKey#EnableZoneAffinity或CommonClientConfigKey#EnableZoneExclusivity设置为true，则将打开此筛选。打开时，同一区域外的服务器（如服务器#getZone（）所示）将被过滤掉。默认情况下，区域亲缘关系和排他性处于关闭状态，不过滤任何内容。
