1. 创建Kafka消费者 首先,我们需要创建一个Kafka消费者。下面是一个简单的Kafka消费者示例: importorg.apache.kafka.clients.consumer.ConsumerConfig;importorg.apache.kafka.clients.consumer.KafkaConsumer;importjava.util.Properties;Propertiesprops=newProperties();props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG,"l...

To run the consumer and producer example, use the following steps:Fork/Clone the repository to your development environment. Install Java JDK 8 or higher. This was tested with Oracle Java 8, but should work under things like OpenJDK as well. Install Maven. Assuming Java and Maven are both ...
