我有一个带有分离器（使用流）的camel路由，它将消息发送到要处理的seda队列 . 当我试图轻轻地停止应用程序时，seda队列不会立即停止，它会在最终关闭之前处理所有消息 . 我该怎么做才能马上阻止它？
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.concurrent.TimeUnit;
import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.apache.camel.builder.ExpressionBuilder;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.main.Main;
public class MySedaShutdownTest extends RouteBuilder {
@Override
public void configure() throws Exception {
onException(Exception.class)
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
System.out.println("exception");
}
});
from("timer:myTimer?repeatCount=1")
.split(ExpressionBuilder.beanExpression(new MySplitter(), "myIterator"))
.streaming()
.to("seda:mySeda");
from("seda:mySeda")
.throttle(1)
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
System.out.println("processing: " + exchange.getIn().getBody()
+ "; app status: " + exchange.getContext().getStatus());
}
});
}
public static class MySplitter {
public Iterator<String> myIterator() {
List<String> values = new ArrayList<String>();
for (int i = 0; i < 10; i++) {
values.add("string nr : " + i);
}
System.out.println("in myIterator");
return values.iterator();
}
}
public static void main(String[] a) throws Exception {
final Main main = new Main();
new Thread(new Runnable() {
@Override
public void run() {
try {
TimeUnit.SECONDS.sleep(4);
} catch (InterruptedException e) {
e.printStackTrace();
}
try {
System.out.println("invoking shutdown");
main.shutdown();
} catch (Exception e) {
e.printStackTrace();
}
}
}).start();
System.out.println("starting app");
main.enableHangupSupport();
main.addRouteBuilder(new MySedaShutdownTest());
main.run();
}
}

SedaEndpoint上有一个purgeQueue方法 . 因此，您可以获取 endpoints 并调用此方法 . 您也可以从JMX访问它 .
有点相关我们有这张改进的票
我为此记录了一张票
只需在下面添加字符串作为 configure() 方法的第一行：
它会将关机超时从300秒（默认）减少到1
