Group received messages in RabbitMQ, preferably using Spring AMQP?

阅读更多关于 Group received messages in RabbitMQ, preferably using Spring AMQP?

问题 I'm receiving messages from a service (S) that publishes each individual property change to an entity as a separate message. A contrived example would be an entity like this: Person { id: 123 name: "Something", address: {...} } If name and address are updated in the same transaction then (S) will publish two messages, PersonNameCorrected and PersonMoved . The problem is on the receiving side where I'm storing a projection of this Person entity and each property change causes a write to the

Spring Batch with multi tenancy

问题 How do we define spring batch jobs to run against multiple tenants? I have setup to run a sequence of jobs in order every night against one database schema currently. All the jobs currently read files from a location and insert to database.The batch configuration was very basic where I defined a data-source, transaction manager and mapped job-repository to it. My jobs will point to this repository and transaction manager. Also I am currently persisting batch meta data information in database.

How to read and process multiple files concurrently in spring?

阅读更多关于 How to read and process multiple files concurrently in spring?

问题 I am new to Spring framework and I am doing one simple project using spring and got stuck in between. In my project I am reading the file from directory using spring poller. And then processing that file through various channels and sending it to the queue. But problem is that "file-inbound-channel-adapter" (which I'm using ) is reading only one file at a time. So I need a solution which will read and process multiple files at a time. Is there any way to implement multithreading in spring

Spring integration: How processing files sequentially

阅读更多关于 Spring integration: How processing files sequentially

问题 I use "int-file: inbound-channel-adapter" to load files which exist into a directory. And i like to process files sequentially: it means that when the processing of the first file is completed, I load the second file ...etc. I see a sample but I can't forcast the needed period to processing one file which depends on its size. My source code: <int-file:inbound-channel-adapter directory="${directory.files.local}" id="filesIn" channel="channel.filesIn"> <int:poller fixed-delay="1000" max

阅读更多关于 Spring Integration application does not define channels when executed as packaged jar

问题 I started to use Spring Integration in a project at work. Everything was looking fine and running smoothly on my local dev environment (when executed from Eclipse). However, when I tried to deploy to our dev/staging environment I got some issues related with the definition of the Spring Integration channels. After a couple of hours completely clueless (blaming external dependencies, our development/staging environment setup etc etc), I came to realize that I would get exactly the same issue

Automatic retry connection to broker by spring-rabbitmq

阅读更多关于 Automatic retry connection to broker by spring-rabbitmq

问题 I have read this fragment of docs: RabbitMQ Automatic Connection/Topology recovery Since the first version of Spring AMQP, the framework has provided its own connection and channel recovery in the event of a broker failure. Also, as discussed in Section 3.1.10, “Configuring the broker”, the RabbitAdmin will re-declare any infrastructure beans (queues etc) when the connection is re-established. It therefore does not rely on the Auto Recovery that is now provided by the amqp-client library.
