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：
1. 使用最高版本2.1.0.RELEASE集成jar包：spring-integration-kafka

2. Zookeeper、Kafka分布式集群使用init.properties配置化方案。

kafka.servers=127.0.0.1:9092  
kafka.topic=xxxooo

 
3. 使用消息生产者spring-context-producer配置化方案。

<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans"  
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
     xmlns:context="http://www.springframework.org/schema/context"  
     xsi:schemaLocation="http://www.springframework.org/schema/beans  
         http://www.springframework.org/schema/beans/spring-beans.xsd  
         http://www.springframework.org/schema/context  
         http://www.springframework.org/schema/context/spring-context.xsd"> 


	<!-- 定义producer的参数 -->
	<bean id="producerProperties" class="java.util.HashMap">
		<constructor-arg>
			<map>
				<entry key="bootstrap.servers" value="localhost:9092" />
				<entry key="group.id" value="2" />
				<entry key="retries" value="10" />
				<entry key="batch.size" value="16384" />
				<entry key="linger.ms" value="1" />
				<entry key="buffer.memory" value="33554432" />
				<entry key="key.serializer"
					value="org.apache.kafka.common.serialization.IntegerSerializer" />
				<entry key="value.serializer"
					value="org.apache.kafka.common.serialization.StringSerializer" />
			</map>
		</constructor-arg>
	</bean>

	<!-- 创建kafkatemplate需要使用的producerfactory bean -->
	<bean id="producerFactory"
		class="org.springframework.kafka.core.DefaultKafkaProducerFactory">
		<constructor-arg>
			<ref bean="producerProperties" />
		</constructor-arg>
	</bean>

	<!-- 创建kafkatemplate bean，使用的时候，只需要注入这个bean，即可使用template的send消息方法 -->
	<bean id="KafkaTemplate" class="org.springframework.kafka.core.KafkaTemplate">
		<constructor-arg ref="producerFactory" />
		<constructor-arg name="autoFlush" value="true" />
		<property name="defaultTopic" value="test" />
	</bean>
</beans>

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

<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans"  
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
     xmlns:context="http://www.springframework.org/schema/context"  
     xsi:schemaLocation="http://www.springframework.org/schema/beans  
         http://www.springframework.org/schema/beans/spring-beans.xsd  
         http://www.springframework.org/schema/context  
         http://www.springframework.org/schema/context/spring-context.xsd"> 


	<!-- 定义consumer的参数 -->
	<bean id="consumerProperties" class="java.util.HashMap">
		<constructor-arg>
			<map>
				<entry key="bootstrap.servers" value="localhost:9092" />
				<entry key="group.id" value="0" />
				<entry key="enable.auto.commit" value="true" />
				<entry key="auto.commit.interval.ms" value="1000" />
				<entry key="session.timeout.ms" value="15000" />
				<entry key="key.deserializer"
					value="org.apache.kafka.common.serialization.IntegerDeserializer" />
				<entry key="value.deserializer"
					value="org.apache.kafka.common.serialization.StringDeserializer" />
			</map>
		</constructor-arg>
	</bean>

	<!-- 创建consumerFactory bean -->
	<bean id="consumerFactory"
		class="org.springframework.kafka.core.DefaultKafkaConsumerFactory">
		<constructor-arg>
			<ref bean="consumerProperties" />
		</constructor-arg>
	</bean>

	<!-- 实际执行消息消费的类 -->
	<bean id="messageListernerConsumerService" class="com.sml.sz.kafka.KafKaConsumer" />

	<!-- 消费者容器配置信息 -->
	<bean id="containerProperties"
		class="org.springframework.kafka.listener.config.ContainerProperties">
		<constructor-arg value="test" />
		<property name="messageListener" ref="messageListernerConsumerService" />
	</bean>

	<!-- 创建kafkatemplate bean，使用的时候，只需要注入这个bean，即可使用template的send消息方法 -->
	<bean id="messageListenerContainer"
		class="org.springframework.kafka.listener.KafkaMessageListenerContainer"
		init-method="doStart">
		<constructor-arg ref="consumerFactory" />
		<constructor-arg ref="containerProperties" />
	</bean>
</beans>

 
5. 使用注解方式注入消息类型

@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;
	
  

}

@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);

	}

}
