Here is the point of the documentation: http://docs.spring.io/spring-integration/reference/htmlsingle/#security-context-propagation My perplexity are the following: (1) To be sure that our interaction with the application is secure, according to its security system rules, we should supply some security context with an authentication (principal) object. The Spring Security project provides a flexible, canonical

问题 In multiple forum threads, people are talking about a "manual mode" when editing spring-integration xml file in integration-graph tab. The problem is I'm unable to find a way to access this manual mode and to change the layout of the default provided graph (which is a complete mess). I tried to change the position of elements but I get a red cross and I can find a button that says switch to manual mode or something like that? Could someone help ? My Env : Eclipse 4.4.2 + Spring IDE plugin 3.6

问题 I am working on below configuration for messaging using Spring and Webphere MQ. I have a requirement of implementing retrying logic for a scenario, where I receive a message from the queue and put the message data on to a Elastic search server (search server is non transactional), if the search server is down I have to rollback the message on to the queue again and process the message after some interval of time(for example: 30 seconds) . this retry has to be done for 5 times. after 5 times

问题 I have an issue with spring-boot-stream during some attempts for consume multiple topics in one @StreamListener . According to spring-cloud-stream docs: Accordidng to docs: destination The target destination of a channel on the bound middleware (e.g., the RabbitMQ exchange or Kafka topic). If the channel is bound as a consumer, it could be bound to multiple destinations and the destination names can be specified as comma separated String values . If not set, the channel name is used instead.

问题 I have a some questions regarding transactions in DMLC and JMSTemplate. Does Spring DMLC receive messages asynchronously using callbacks if we are not using transactions ? Does DMLC also receive messages asynchronous while using transacted session. (setting sessionTransacted to true). What is the behavior after setting sessionTransacted to true ? 3, What is the difference between AUTO_ACK and SESSION_TRANSACTED mode from consumer's prospective. In AUTO_ACK mode DMLC send acknowledgement to

问题 I am creating a system using cloud-dataflow, I have a source and a transformer. We like to use kryo, but some of our classes require custom kryo serializers, I have written serializers before. We are now using spring-integration-core-4.3.11, and since 4.2 the model has changes(per the docs) to use Codecs instead of MessageConverter interface. The question is, how can I register the kryo serializers in the new Codec framework, do I make a new Codec implementation inheriting from MessageCodec?
