我正在尝试使用Spring Boot，Spring Batch和Spring Integrations配置RemoteChunking任务。
我已经配置了一个activeMQ服务器，我开始按照官方文档https://docs.spring.io/spring-batch/4.0.x/reference/html/spring-batch-integration.html#remote-chunking配置Spring Batch。
我的主配置：

它似乎工作正常，但是当从机完成一个块时，它会向主机发送一个响应，完成作业，从机显示“超时错误”：

我认为你的问题出在worker这边：
@Bean
public IntegrationFlow outgoingReplies() {
return IntegrationFlows
.from("replies")
.handle(Jms
.outboundGateway(connectionFactory())
.requestDestination("replies"))
.get();
}
你只是发送回复，除了主人的任何东西你都没有。
它必须是单向的
Jms
.outboundAdapter(connectionFactory())
.destination("replies")`
