问题 I would like to route the message to different channels based on the condition of the property. Let's say I have score property. If the score is <100 then it goes to "perfectchannel" else it goes to "normalchannel" Where do I specify the spel expression or condition <si:router id="serviceRouter" input-channel="serviceRoutingChannel" expression="payload.score" default-output-channel="badchannel" resolution-required="false"> <si:mapping value="100" channel="perfectchannel" /> <si:mapping value=

问题 I want to wrap the call to outbound gateway in my integration application using hystrix command similar to how it is available in Spring boot application. <int-http:outbound-gateway id="outbound.gateway" request-channel="get.request.channel" url="http://localhost:9090/profileapplication" http-method="GET" charset='UTF-8' reply-channel="reply.channel" > </int-http:outbound-gateway> I have my outbound gateway as above.

问题 I'm using spring integration aws to poll an S3 resource and get files from the S3 bucket and process them using spring integration. Below is what i have : AmazonS3 amazonS3 = new AmazonS3Client(new BasicAWSCredentials(accessKey, secretKey)); @Bean IntegrationFlow fileReadingFlow() { return IntegrationFlows .from(s3InboundFileSynchronizingMessageSource(), e -> e.poller(p -> p.fixedDelay(30, TimeUnit.SECONDS))) .handle(receiptProcessor()) .get(); } @Bean public S3InboundFileSynchronizer

问题 We have a requirement for the FTP client to download a file whose name and directory is provided at run-time. So, the FTP client may be asked to download file1.txt from foo1/foo2 directory path on the remote server. We do have a solution using Spring Integration FTP outbound gateway. With this solution to make it dynamic: the ApplicationContext for the gateway is created the gateway properties get set using file name and remote directory path the file is downloaded the ApplicationContext is

问题 I have a spring input channel defined like this <file:inbound-channel-adapter prevent-duplicates="false" id="inpChannel" directory="file:/Users/abhisheksingh/req" auto-startup="true"> <int:poller id="poller" fixed-delay="1000" /> </file:inbound-channel-adapter> <int:service-activator input-channel="inpChannel" ref="inpHandler" /> The file name example as TEST.SQQ. SQQ is the file format which the client uses to place the files in ftp. However, I see that the same file is picked up by the

问题 This particular piece makes sense to implement in the application rather than XML because it is a constant across the entire cluster, not localized to a single job. From dissecting the XSD, it looks to me like the xml for int-kafka:outbound-channel-adapter constructs a KafkaProducerMessageHandler. There is no visible way to set the channel, the topic, or most of the other attributes. Note to potential downvoters - (rant on) I have been RTFM'ing for a week and am more confused than when I

问题 In my development environment I'm using two separate technology stacks for the frontend and the backend: React + webpack-dev-server for the frontend, served at localhost:8081 Spring for the backend, serving HTTP endpoints over localhost:7080 , in two ways: using integration for the data processing (reception, transformation and storage), this processing starts at an http:inbound-channel-adapter (see the following XML configuration) using MVC to provide a read-only (i.e. GET-only) access

问题 I am working on simple project that will lunch a job when a new file is created in specific folder but i don't want to use xml only java annotation , so my question is how can i implement the below in code <batch-int:job-launching-gateway request-channel="outboundJobRequestChannel" reply-channel="jobLaunchReplyChannel"/> <int:logging-channel-adapter channel="jobLaunchReplyChannel"/> BR Shahbour 回答1: Use the Spring Integration Java DSL; in your case, you would use ... .handle(jobLauncher())

问题 I need to make a small Spring Integration application that synchronize a table from a JDBC source to another one, and I just need to launch that script just once in a while. I'd like to make one poll from the inbound channel adapter (wait that the message flow through the chain) and exit the application. I couldn't find any obvious way to do that: any suggestions? 回答1: @Steve suggests correct solution. You should make your <poller> with some long fixed-delay do not start a new polling task.

问题 I have the following spring-integration XML config <ip:tcp-outbound-gateway id="outboundClient" request-channel="requestChannel" reply-channel="string2ObjectChannel" connection-factory="clientConnectionFactory" request-timeout="10000" reply-timeout="10000"/> How can I write the Java config equivalent of the above? I thought the equivalent would be @Bean public TcpOutboundGateway outboundClient() { TcpOutboundGateway tcpOutboundGateway = new TcpOutboundGateway(); tcpOutboundGateway
