the assumption being that if a message +could not be converted on the first attempt, subsequent attempts will also fail. +Such messages are discarded (or dead-lettered). + +== Build + +``` +$ ./mvnw clean install -PgenerateApps +$ cd apps +``` +You can find the corresponding binder based projects here. +You can then cd into one of the folders and build it: +``` +$ ./mvnw clean package +``` + +== Examples + +``` +java -jar rabbit-source.jar --rabbit.queues= +``` + +//end::ref-doc[] \ No newline at end of file diff --git a/applications/source/rabbit-source/pom.xml b/applications/source/rabbit-source/pom.xml new file mode 100644 index 00000000..d30e856c --- /dev/null +++ b/applications/source/rabbit-source/pom.xml @@ -0,0 +1,110 @@ + + + 4.0.0 + rabbit-source + 3.0.0-SNAPSHOT + rabbit-source + Rabbit source apps + jar + + + org.springframework.cloud.stream.app + stream-applications-core + 3.0.0-SNAPSHOT + + + + 1.14.2 + + + + org.springframework.boot + spring-boot-starter-test + test + + + org.junit.vintage + junit-vintage-engine + + + + + org.springframework.cloud.fn + rabbit-supplier + ${java-functions.version} + + + org.springframework.boot + spring-boot-starter-json + test + + + org.testcontainers + testcontainers + ${test-containers-version} + test + + + org.testcontainers + rabbitmq + ${test-containers-version} + test + + + io.projectreactor + reactor-test + test + + + + + + + org.springframework.cloud + spring-cloud-app-starter-doc-maven-plugin + + + org.springframework.cloud.stream.app.plugin + spring-cloud-stream-app-maven-plugin + + + rabbit + source + ${project.version} + org.springframework.cloud.fn.supplier.rabbit.RabbitSupplierConfiguration.class + + + + + org.springframework.cloud.fn + rabbit-supplier + ${java-functions.version} + + + + + + + + + + + + true + + spring-snapshots + Spring Snapshots + https://repo.spring.io/libs-snapshot-local + + + + false + + spring-milestones + Spring Milestones + https://repo.spring.io/libs-milestone-local + + + + diff --git a/applications/source/rabbit-source/src/main/resources/META-INF/dataflow-configuration-metadata-whitelist.properties b/applications/source/rabbit-source/src/main/resources/META-INF/dataflow-configuration-metadata-whitelist.properties new file mode 100644 index 00000000..04900eac --- /dev/null +++ b/applications/source/rabbit-source/src/main/resources/META-INF/dataflow-configuration-metadata-whitelist.properties @@ -0,0 +1,2 @@ +configuration-properties.classes=org.springframework.cloud.fn.supplier.rabbit.RabbitSupplierProperties, \ + org.springframework.boot.autoconfigure.amqp.RabbitProperties diff --git a/applications/source/rabbit-source/src/test/java/org/springframework/cloud/stream/app/source/rabbit/RabbitSourceInvalidConfigTests.java b/applications/source/rabbit-source/src/test/java/org/springframework/cloud/stream/app/source/rabbit/RabbitSourceInvalidConfigTests.java new file mode 100644 index 00000000..0fe273ee --- /dev/null +++ b/applications/source/rabbit-source/src/test/java/org/springframework/cloud/stream/app/source/rabbit/RabbitSourceInvalidConfigTests.java @@ -0,0 +1,83 @@ +/* + * Copyright 2016-2020 the original author or authors. + * + * Licensed under the Apache License, Version 2.0 (the "License");
