Spring boot Spring集成DSL-JdbcPollingChannelAdapter结果未排队
我发誓我已经做到了,但是当我在几个月后(以及升级到Boot 1.5.9)能够回到它的时候,我遇到了一些问题 我设置了一个JdbcPollingChannelAdapter,可以很好地执行receive(),但是当我将适配器放入一个只对适配器结果进行排队的流中时,队列上的running.receive总是返回null(不过我可以在控制台日志中看到适配器的SQL正在执行) 测试如下。为什么我可以从适配器获取结果,但不能将结果排队?提前感谢您的帮助Spring boot Spring集成DSL-JdbcPollingChannelAdapter结果未排队,spring-boot,spring-integration,spring-integration-dsl,Spring Boot,Spring Integration,Spring Integration Dsl,我发誓我已经做到了,但是当我在几个月后(以及升级到Boot 1.5.9)能够回到它的时候,我遇到了一些问题 我设置了一个JdbcPollingChannelAdapter,可以很好地执行receive(),但是当我将适配器放入一个只对适配器结果进行排队的流中时,队列上的running.receive总是返回null(不过我可以在控制台日志中看到适配器的SQL正在执行) 测试如下。为什么我可以从适配器获取结果,但不能将结果排队?提前感谢您的帮助 @RunWith(SpringRunner.clas
