延期的.可延期的
Java 中的 deferred.defer 有什么计划吗?
import static com.google.appengine.api.labs.taskqueue.TaskOptions.Builder.taskName;
import java.io.IOException;
import javax.servlet.ServletException;
import com.newatlanta.appengine.taskqueue.Deferred;

public class SampleTask implements Deferrable {

public SampleTask() {
}
public SampleTask(String arg1, String arg2) {
// save information to use later
this.arg1 = arg1;
this.arg2 = arg2;
}
@Override
public void doTask() throws ServletException, IOException {
// TODO do work here
// this is how you 'schedule' a task
// doing this here is recursive;
// you most likely want to call this from
// a server rpc endpoint
SampleTask task = new SampleTask("arg1", "arg2");
Deferred.defer(task, "queue-name", taskName("task-name"));
}
}
