spring+springmvc+kafka分布式消息中间件集成方案
Honghu的消息服务平台已经抛弃了之前的ActiveMQ，改用高吞吐量比较大的Kafka分布式消息中间件方案：
kafka消息平台使用spring+kafka的集成方案，详情如下：
-
使用最高版本2.1.0.RELEASE集成jar包：spring-integration-kafka
-
Zookeeper、Kafka分布式集群使用init.properties配置化方案。
Java代码
kafka.servers=127.0.0.1:9092
kafka.topic=xxxooo
- 使用消息生产者spring-context-producer配置化方案。

- 使用消息消费者spring-context-producer配置化方案。

class="org.springframework.kafka.listener.KafkaMessageListenerContainer"
init-method="doStart">

<constructor-arg ref="containerProperties" />
</bean>
</beans>
- 使用注解方式注入消息类型
@Autowired
private KafkaTemplate
-
重写MessageListener 的getMessage方法获取消息（业务实现）
-
RestFul服务方式测试消息服务
Java代码
@CrossOrigin(origins = "*", maxAge = 3600, methods = { RequestMethod.GET, RequestMethod.POST, RequestMethod.DELETE,
RequestMethod.PUT })
@RestController
@RequestMapping(value = "/rest/kafka")
public class KafKaProducer {
@RequestMapping(value = "/send", method = RequestMethod.GET)
public JSONObject save() {
System.out.println("+++++++++++++++++++++++++++++++");
kafkaTemplate.sendDefault("HongHu KAFKA分布式消息服务测试");
return null;
}
@Autowired
private KafkaTemplate<Integer, String> kafkaTemplate;
}
Java代码
@RestController
public class KafKaConsumer implements MessageListener<Integer, String> {
@Autowired
private LogService logService;
public void onMessage(ConsumerRecord<Integer, String> records) {
System.out.println("====================" + records);
Object o = records.value();
Log log = new Log();
log.setIsNewRecord(true);
log.setId(IdGen.uuid());
log.setTitle(String.valueOf(o));
logService.save(log);
}
}
接受消息了------------------:ConsumerRecord(topic = xxxooo, partition = 0, offset = 2489, CreateTime = 1479647648299, checksum = 3372898135, serialized key size = -1, serialized value size = 40, key = null, value = HongHu KAFKA分布式消息服务测试)
