functions can be composed, and how the final result can be bound to RabbitMQ destination by the https://spring.io/projects/spring-cloud-function[Spring Cloud Stream] framework. +The goal of this sample is to poll zip files, unzip them, and emit messages to RabbitMQ for every line of text from those zip entries. + +The sample uses these dependencies: + +[source,groovy] +---- +implementation 'org.springframework.cloud:spring-cloud-stream-binder-rabbit' +implementation 'org.springframework.integration:spring-integration-zip' +implementation 'org.springframework.cloud.fn:spring-file-supplier' +implementation 'org.springframework.cloud.fn:spring-splitter-function' +---- + +The first one is for binding output of the composed function into a RabbitMQ destination. +The second one is for `UnZipTransformer`, which we use for a custom function to unzip polled files by the `fileSupplier`. +The `splitterFunction` is used in a `FileSplitter` mode to read lines from unzipped entries and emit each of them as an individual message. +Essentially, we are splitting twice: zip entries, and content of each file. + +The composition is like this: `fileSupplier|unzipFunction|splitterFunction|flattenFunction`. +(The `flattenFunction` will be explained latter). +The result of this composition is a `Supplier>>` and we bind it into a RabbitMQ `unzipped_data_exchange` using Spring Cloud Stream. + +For `fileSupplier` we provide these configuration properties: + +[source,yaml] +---- +file: + supplier: + directory: # Set some real dir with zips to process + filename-pattern: '*.zip' +---- + +Poll only zip files from the provided directory. +The sample doesn't come with one, so it's up to an end-user to provide specific directory with zip files. +Or this `fileSupplier` could be replaced with any other file-based supplier. + +The `splitterFunction` comes with this property: + +[source,yaml] +---- +splitter: + charset: UTF-8 +---- + +Which is a trigger for that function to use a `FileSplitter` for zip entries to emit their lines of text as individual messages. + +The custom `ZipSplitRabbitBinderApplication.unzipFunction()` (might be a candidate for the future Functions Catalog version) uses `Flux` API to unzip polled files via `UnZipTransformer` and then `flatMapIterable()` for zip entries. +Then those entries are fed into a `splitterFunction` for `FileSplitter` mode. + +The mention `ZipSplitRabbitBinderApplication.flattenFunction()` is needed for now here since `splitterFucntion` produces a `List` which cannot be https://docs.spring.io/spring-cloud-stream/reference/spring-cloud-stream/producing-and-consuming-messages.html#batch-producers[de-batched] by Spring Cloud Stream since our final product of the composition is, essentially, `Supplier>>`. + +To run the application from main `ZipSplitRabbitBinderApplication` class (`./gradlew bootRun`), the RabbitMQ broker must be supplied on the target environment. + +The test environment for this sample uses `org.springframework.boot:spring-boot-testcontainers` and `org.testcontainers:rabbitmq` to run RabbitMQ in Docker container and wire it properly into Spring Boot auto-configuration. +The `ZipSplitRabbitBinderApplicationTests` uses `dirWithZips` directory from classpath with two zip files. +Then the `fileSupplier` polls those files and emits them into the mentioned function composition. +The `@RabbitListener` in the test configuration bind an anonymous queue to the mentioned `unzipped_data_exchange` topic exchange to consume produced data from our functions composition. +The test, by itself, verifies that all consumed by `@RabbitListener` data is, essentially, lines from the mentioned zipped files. \ No newline at end of
