DUBBO timeout 请求超时问题

线上问题

同样的处理， 请求A，B，C都没问题， 只有C有问题，线上报以下错误，分析之后是因为dubbo 超时的问题，因为请求C的后台逻辑比较复杂，dubbo的消费端<dubbo:consumer timeout="5000" check="false"/>设置的超时时间太短的原因造成。

Failed to invoke the method getQyhx in the service com.zstimes.fpfx2.service.IFpfxOuterService.

Tried 3 times of the providers [192.168.100.57:20881] (1/1) from the registry 192.168.100.57:2181 on the consumer 192.168.100.74 using the dubbo version 2.8.4a.

解决：

<dubbo:consumer timeout="20000" check="false"/>

dubbo的消费者配置问题件中 把timeout时间变大， 重新发布消费端。 解决问题。
