Spring integration 来自控制器的Spring批处理集成启动/停止文件适配器

我不确定我的端点是否设置正确。我的最终目标是，当我在两个适配器上调用stop时，如果一个文件被放置在入站通道适配器轮询的任一目录中，该文件将不会被处理。但事实并非如此——文件仍在进行轮询和处理

当前，当代码运行时，从一开始就启动6个任务调度器：

2015-08-03 18:12:40,011 [task-scheduler-6] DEBUG org.springframework.integration.endpoint.SourcePollingChannelAdapter - Received no Message during the poll, returning 'false'
2015-08-03 18:12:40,011 [task-scheduler-5] DEBUG org.springframework.integration.endpoint.SourcePollingChannelAdapter - Received no Message during the poll, returning 'false'

2015-08-03 18:12:40,011 [task-scheduler-1] DEBUG org.springframework.integration.endpoint.SourcePollingChannelAdapter - Received no Message during the poll, returning 'false'

当我发出停止信号时

@'mecFilePoller.fileMessageSourceMDW.inboundChannelAdapter'.stop()

在其中一个适配器上，我只剩下5个任务调度器。以下是正在发出的停止命令：

下面是第一个stop命令后生成的任务调度程序，现在只有5个：

2015-08-03 18:15:30,017 [task-scheduler-2] DEBUG org.springframework.integration.endpoint.SourcePollingChannelAdapter - Received no Message during the poll, returning 'false'

当我在第二个适配器上发出第二个停止时

@'mecFilePoller.fileMessageSourceSSN.inboundChannelAdapter'.stop()

命令如下：

我只剩下4个任务调度器：

入站通道适配器由（至少两个）bean组成；在本例中，使用

MessageSource

和

SourcePollingChannelAdapter

在您的示例中，消息源获取指定的bean名称（

filePoller

）。将生成通道适配器的名称，并将

filePoller.fileMessageSource.inboundChannelAdapter

（

@Configuration

类bean名称+方法名称+类型）

我们有一个文档来记录这些生成的bean名称

由于名称为虚线，因此在使用控制总线时需要引用：

@'filePoller.fileMessageSource.inboundChannelAdapter'.stop()

编辑

我刚测试过这个，效果很好

@Configuration
@EnableIntegration
public class Foo {

    @Bean
    QueueChannel inboundFileChannel() {
        return new QueueChannel();
    }

    @Bean
    @InboundChannelAdapter(value = "inboundFileChannel", poller = @Poller(fixedDelay="1000"))
    public MessageSource<?> fileMessageSource() {
        MessageSource<?> source = mock(MessageSource.class);
        return source;
    }

    @Bean
    MessageChannel control() {
        return new DirectChannel();
    }

    @Bean
    @ServiceActivator(inputChannel="control")
    public ExpressionControlBusFactoryBean controlBus() {
        return new ExpressionControlBusFactoryBean();
    }

    public static void main(String[] args) throws Exception {
        AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(Foo.class);
        Thread.sleep(2000);
        ctx.getBean("control", MessageChannel.class).send(
                new GenericMessage<String>("@'foo.fileMessageSource.inboundChannelAdapter'.stop()"));
        assertFalse(ctx.getBean(SourcePollingChannelAdapter.class).isRunning());
        Thread.sleep(2000);
        ctx.close();
    }
}

（停止后不进行投票）。

谢谢。但当我将其更改为control.send（新的GenericMessage（“@'filePoller.fileMessageSource.inboundChannelAdapter.stop（）”）时，我得到了错误org.springframework.expression.spel.SpelEvaluationException:EL1058E:（位置1）：尝试解析bean“filePoller.fileMessageSource.inboundChannelAdapter”时出现问题：“无法解析针对BeanFactory的bean引用”。本质上，NoSuchBeanDefinitionException：没有定义名为“filePoller.fileMessageSource.inboundChannelAdapter”的bean从bean中删除名称，或者更改名称，或者重命名配置类；配置类

FilePoller

获取bean名

FilePoller

。这可能是问题的根源。谢谢你，加里。我照你说的做了。将我的类更新为MECFilePoller，将我的bean名更新为（不同于类名）mdwFilePoller。我的文件消息源方法现在也是fileMessageSourceMDW。我现在向控制总线发送的命令是：control.send（新的GenericMessage（“@'mdwFilePoller.fileMessageSourceMDW.inboundChannelAdapter.stop（）”）。不幸的是，我仍然没有定义名为“mdwFilePoller.fileMessageSourceMDW.inboundChannelAdapter”的bean，如果您的类是

MECFilePoller

，则bean名称是

MECFilePoller

而不是

mdw…

。我刚刚在我的答案中粘贴了一个测试，效果很好。太好了。虽然我认为它会立即停止投票？我仍然看到轮询消息：SourcePollingChannelAdapter-在轮询期间没有收到任何消息，返回“false”，即使在调用stop之后也是如此。
