This commit updates URLs to prefer the https protocol. Redirects are not followed to avoid accidentally expanding intentionally shortened URLs (i.e. if using a URL shortener). # Fixed URLs ## Fixed But Review Recommended These URLs were fixed, but the https status was not OK. However, the https status was the same as the http request or http redirected to an https URL, so they were migrated. Your review is recommended. * http://services.gradle.org/distributions/gradle- (404) with 1 occurrences migrated to: https://services.gradle.org/distributions/gradle- ([https](https://services.gradle.org/distributions/gradle-) result 404). ## Fixed Success These URLs were switched to an https URL with a 2xx status. While the status was successful, your review is still recommended. * http://maven.apache.org/xsd/maven-4.0.0.xsd with 63 occurrences migrated to: https://maven.apache.org/xsd/maven-4.0.0.xsd ([https](https://maven.apache.org/xsd/maven-4.0.0.xsd) result 200). * http://www.apache.org/licenses/LICENSE-2.0 with 4 occurrences migrated to: https://www.apache.org/licenses/LICENSE-2.0 ([https](https://www.apache.org/licenses/LICENSE-2.0) result 200). * http://www.apache.org/licenses/LICENSE-2.0.txt with 64 occurrences migrated to: https://www.apache.org/licenses/LICENSE-2.0.txt ([https](https://www.apache.org/licenses/LICENSE-2.0.txt) result 200). * http://projects.spring.io/spring-integration with 64 occurrences migrated to: https://projects.spring.io/spring-integration ([https](https://projects.spring.io/spring-integration) result 301). * http://repo.spring.io/libs-milestone with 2 occurrences migrated to: https://repo.spring.io/libs-milestone ([https](https://repo.spring.io/libs-milestone) result 302). * http://repo.spring.io/libs-snapshot with 2 occurrences migrated to: https://repo.spring.io/libs-snapshot ([https](https://repo.spring.io/libs-snapshot) result 302). * http://repo.spring.io/libs-staging-local with 1 occurrences migrated to: https://repo.spring.io/libs-staging-local ([https](https://repo.spring.io/libs-staging-local) result 302). # Ignored These URLs were intentionally ignored. * http://maven.apache.org/POM/4.0.0 with 126 occurrences * http://www.w3.org/2001/XMLSchema-instance with 63 occurrences
Apache Kafka Sample
This example demonstrates the use Kafka Outbound Channel Adapter and Message-Driven Channel Adapter.
It uses Java configuration for the adapters.
Running the sample
Start Apache Zookeeper and Apache Kafka according to the documentation for the Apache Kafka project.
$ gradlew :kafka:run
This will package the application and run it using the Gradle Application Plugin
Using an IDE such as SpringSource Tool Suite™ (STS)
In STS (Eclipse), go to package org.springframework.integration.samples.kafka, right-click Application and select Run as --> Java Application (or Spring Boot Application).
Output
The application sends 10 messages (foo0 ... foo9) to a kafka topic si.topic (which is created if necessary).
The message-driven adapter receives the messages and places them in a QueueChannel which the application reads and
writes to stdout:
GenericMessage [payload=foo0, headers={kafka_offset=21, kafka_messageKey=si.key, kafka_topic=si.topic, kafka_partitionId=0, kafka_nextOffset=22}]
GenericMessage [payload=foo1, headers={kafka_offset=22, kafka_messageKey=si.key, kafka_topic=si.topic, kafka_partitionId=0, kafka_nextOffset=23}]
GenericMessage [payload=foo2, headers={kafka_offset=23, kafka_messageKey=si.key, kafka_topic=si.topic, kafka_partitionId=0, kafka_nextOffset=24}]
GenericMessage [payload=foo3, headers={kafka_offset=24, kafka_messageKey=si.key, kafka_topic=si.topic, kafka_partitionId=0, kafka_nextOffset=25}]
GenericMessage [payload=foo4, headers={kafka_offset=25, kafka_messageKey=si.key, kafka_topic=si.topic, kafka_partitionId=0, kafka_nextOffset=26}]
GenericMessage [payload=foo5, headers={kafka_offset=26, kafka_messageKey=si.key, kafka_topic=si.topic, kafka_partitionId=0, kafka_nextOffset=27}]
GenericMessage [payload=foo6, headers={kafka_offset=27, kafka_messageKey=si.key, kafka_topic=si.topic, kafka_partitionId=0, kafka_nextOffset=28}]
GenericMessage [payload=foo7, headers={kafka_offset=28, kafka_messageKey=si.key, kafka_topic=si.topic, kafka_partitionId=0, kafka_nextOffset=29}]
GenericMessage [payload=foo8, headers={kafka_offset=29, kafka_messageKey=si.key, kafka_topic=si.topic, kafka_partitionId=0, kafka_nextOffset=30}]
GenericMessage [payload=foo9, headers={kafka_offset=30, kafka_messageKey=si.key, kafka_topic=si.topic, kafka_partitionId=0, kafka_nextOffset=31}]
Notice that the offset header increases on each run (the topic is not removed, to demonstrate that the offset is retained between executions).
