Zuul網關報錯com.netflix.zuul.exception.ZuulException: Forwarding error的解決方法

在給某個方法加了雙重循環後，請求時網關報了

com.netflix.zuul.exception.ZuulException: Forwarding error

com.netflix.client.ClientException: null

java.lang.RuntimeException: java.net.SocketTimeoutException: Read timed out

java.net.SocketTimeoutException: Read timed out

控制檯截圖

 經查原因是zuul的調用等待時間超時，需要在application.yml設置超時連接時長

需要加上（具體時長視情況而定）

ribbon:
  ReadTimeout: 60000
  ConnectTimeout: 60000
zuul:
  host:
