Examples with TimeoutException org.apache.dubbo.remoting.TimeoutException used on opensource projects

Example 1 with TimeoutException

use of org.apache.dubbo.remoting.TimeoutException in project dubbo by alibaba.

the class DefaultFutureTest method timeoutNotSend.

/**
 * for example, it will print like this:
 * before a future is create , time is : 2018-06-21 15:06:17
 * after a future is timeout , time is : 2018-06-21 15:06:22
 * <p>
 * The exception info print like:
 * Sending request timeout in client-side by scan timer.
 * start time: 2018-06-21 15:13:02.215, end time: 2018-06-21 15:13:07.231...
