com netflix zuul exception ZuulException Forwarding error

解决办法

hystrix:  command:    default:      execution:        isolation:          thread:            timeoutInMilliseconds: 60000 ribbon:    ReadTimeout: 60000    ConnectTimeout: 60000  zuul:  host:     connect-timeout-millis: 10000    socket-timeout-millis: 60000

根据情况，有可能是ribbon的问题，也可能不需要设置 ribbon
