If you do not specify a server property for the MBean, the MBeanExporter object attempts to detect an MBeanServer instance that is running".

问题 I'm receiving email with spring, with a very basic script so far ApplicationContext ac = new ClassPathXmlApplicationContext("imap.xml"); DirectChannel inputChannel = ac.getBean("receiveChannel", DirectChannel.class); inputChannel.subscribe(message -> { System.out.println(message.getHeaders()); System.out.println(message.getPayload()); MessageHeaders headers = message.getHeaders(); String from = (String) headers.get("mail_from"); }); According to the documentation I thought the headers would

问题 I am using Spring Integration with JTA support through Atomikos and JMS bound to different Webshpere MQ both inbound and outbound.

问题 I am new to spring batch processing. I am using remote chunking where there is a master , multiple slaves and ActiveMQ for messaging. Master has a job and a job launcher and the job launcher has a task-executor which is having following configuration <task:executor id="batchJobExecutor" pool-size="2"queue-capacity="100" /> . Chunk configuration is <bean id="chunkWriter" class="org.springframework.batch.integration.chunk.ChunkMessageChannelItemWriter" scope="step"> <property name=

问题 I am attempting to process a file exactly like this question: read a remote file line by line The one answer to this question suggests to use RemoteFileTemplate but I am attempting to use the -stream option as suggested in the last comment to the answer.

This works happily on windows laptop but

问题 I am using the sample program here to build my code. Everything works fine with the local SFTP test server, When I tested today in my client SFTP servers, it gave me an exception as below. When I debugged I saw the file being written with '.writing' extension on the client's SFTP server. The contents are fine, I don't see any issues with the file that was transferred but the file name is the issue now. After reading through the spring docs, I see that this is the temporary file extension, and

问题 I'm confused about the difference of Channel Adapters and Gateways in spring integration.

If this is the case, why there is a amqp inbound gateway as well as an amqp outbound gateway? What I'm trying to accomplish in the end is the following: Http request received within a controller place message on amqp queue consumer consumes messages and put

问题 In spring-boot-integration app, wrote a custom locker to rename the original file before locking (fileToLock.getAbsolutePath() + ".lock") and expected lock on file so that any other instance will not be able to process the same file . When file is renaming, its coping the contents from original file and additional file is created with filename.lock with contents and original file also existing with size 0 kb without content. Outbound-gateway taking the original file as input which is without
