针对项目bigger-api-service进行权重分配，预期是存储到192.168.91.58这台机器的消息应该比较多，然而实际是只会存储到第一台机器192.168.91.57。
客户端日志：

你好，如何调整默认路由策略，使权重配置生效？ @qmwu2000

你好，修改buildRouterInfo是不是会影响返回的路由结果，比如我从router?domain=bigger-api-service&ip=192.168.166.50&op=xml这个接口抓到的返回信息属性routers，是不是要把权重信息放到这个属性里面？
然后通过cat客户端的TcpSocketSender根据返回的权重去做负载？ @qmwu2000
router?domain=bigger-api-service&ip=192.168.166.50&op=xml返回信息：
<?xml version="1.0" encoding="utf-8"?> <property-config> <property id="startTransactionTypes" value="Cache.;Squirrel."/> <property id="matchTransactionTypes" value="SQL"/> <property id="block" value="false"/> <property id="routers" value="192.168.91.57:2280;192.168.91.58:2280;"/> <property id="sample" value="1.0"/> </property-config>

理解下来，你的意思应该是在服务端做负载，客户端自动会刷新上报的服务器地址 @qmwu2000

并不是固定的。服务端根据domain的hash取余，然后给客户端两个地址。也就是说一样的domain返回给客户端的路由一直一样的。一定程度上避免了domain数据发往多台服务器上。

@shouhualin 这样会导致每台机器消费和存储消息负载不均衡，直接表现在每台cat服务器的cpu、内存、磁盘、宽带使用不均衡，实际生产也是这样的。
