二,Spring boot操作Kafka

1.Spring boot pom依赖

<parent>     <groupId>org.springframework.boot</groupId>     <artifactId>spring-boot-starter-parent</artifactId>     <version>1.5.6.RELEASE</version>     <relativePath/> <!-- lookup parent from repository --> </parent>

3.kafka配置

#kafka相关配置 spring.kafka.bootstrap-servers=阿里云外网ip:9092 #设置一个默认组 spring.kafka.consumer.group-id=defaultGroup #key-value序列化反序列化 spring.kafka.consumer.key-deserializer=org.apache.kafka.common.serialization.StringDeserializer spring.kafka.consumer.value-deserializer=org.apache.kafka.common.serialization.StringDeserializer spring.kafka.producer.key-serializer=org.apache.kafka.common.serialization.StringSerializer spring.kafka.producer.value-serializer=org.apache.kafka.common.serialization.StringSerializer spring.kafka.producer.batch-size=65536 spring.kafka.producer.buffer-memory=524288

@Component public class KafkaSender {     @Autowired     private KafkaTemplate kafkaTemplate;      /**      * 发送消息到kafka,主题为test      */     public void sendTest(){         kafkaTemplate.send("test","hello,kafka  "  + LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS")));     } }
