why can't spring find the @Source bean channel created by spring cloud stream?

由 佐手、 提交于 2019-12-10 22:57:40
问题 I'm trying to use Spring Cloud Stream to publish and consume Kafka messages. I've been working off of the documentation here on Accessing Bound Channels. I'm trying to use a custom name on the channel for my topic, so I have a @Qualifier when I'm trying to inject it, but spring can't find the relevant bean. It says "For each bound interface, Spring Cloud Stream will generate a bean that implements the interface", but the auto-wiring isn't working. The error I'm getting is "Parameter 0 of

问题 I have a simple Spring Boot application using Spring Cloud Stream Rabbit and Eureka Discovery Client. The application works fine together with Eureka Server, and the messaging over RabbitMQ is also working. But if I spin up a Spring Boot Admin Server, the application starts logging health check failures: 2017-06-21 19:47:57.352 INFO 11416 --- [trap-executor-0] c.n.d.s.r.aws.ConfigClusterResolver : Resolving eureka endpoints via configuration 2017-06-21 19:51:25.047 INFO 11416 --- [nio-8303

Spring Cloud Streams RabbitMQ multi-binder vs the Shovel Plugin/Application

由 最后都变了- 提交于 2019-12-10 11:46:17
问题 Let's consider two systems. Each of the systems uses a dedicated messaging broker for communication between its micro-services. We want to communicate these two systems using Spring Cloud Stream. Case A Both the systems use RabbitMQ as a message broker. Which approach is better: Multi-binder ( spring.cloud.stream.binders ) allows connecting to two different administrative domains. "Multi-binder configuration the environment.spring.rabbitmq forces us to create a whole new child application

问题 I'm exploring the the SCDF for orchestrating the existing batch task for my system. I noticed that the SC Stream App Starters already provides some OOTB ready to use streaming applications, which suits my use case of: Extracting xml file from FTP -> the ftp source Customize transformation Upload the transformed xml file to another FTP -> the ftp sink But, my system only requires the above mentioned batch job to be executed at every 10 minutes interval. Implementing it using streams app is

How Spring Cloud Config Server PUSH plain text files to Config Client Application?

问题 What I have implemented so far are: Spring Cloud Config Server with "native" repo. spring.profiles.active: native spring.cloud.config.server.native.searchLocations: file:/path/to/config-repo Config Server is pushing notification to Config Client App through RabbitMQ, as http://cloud.spring.io/spring-cloud-config/spring-cloud-config.html#_push_notifications_and_spring_cloud_bus Config Client App has @RefreshScope annotated on Service bean.

spring.cloud.stream.kafka.binder.headers not working as expected

由 白昼怎懂夜的黑 提交于 2019-12-07 18:28:15
问题 I am trying to use spring.cloud.stream.kafka.binder.headers to transport a custom header that I am setting based upon a previous question. I have read in the documentation where... spring.cloud.stream.kafka.binder.headers The list of custom headers that will be transported by the binder. Default: empty. seems to suggest that setting a list (comma separated?) will cause a custom header to get transported in the Message<> , but the header is lost as soon as the kafka write is completed. My

@MessagingGateway, Spring Cloud Stream, and error handling across both

由 此生再无相见时 提交于 2019-12-06 14:29:26
问题 Regarding the answer posted for How can @MessagingGateway be configured with Spring Cloud Stream MessageChannels?, what is the correct way to handle errors at the @MessagingGateway that can be returned from Spring Cloud Stream services? To recap, I have a @MessagingGateway that provides synchronous access to asynchronous services built using Spring Cloud Stream. When an error occurs within my Spring Cloud Stream service layer, I create an error response and send it through a
