1.新建Maven项目-KafkaMaven

-》点击next按钮

-》点击next按钮

-》点击finish按钮，项目新建成功

2.生产者配置文件：kafka-producer.xml

<?xml version="1.0" encoding="UTF-8"?>

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="0"/>
<entry key="retries" value="10"/>

<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="myTopic"/>
</bean>
</beans>

3.消费者配置文件：kafka-consumer.xml

<?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"

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>

</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.kafka.service.impl.MsgConsumerServiceImpl"/>

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

<bean id="messageListenerContainer" class="org.springframework.kafka.listener.KafkaMessageListenerContainer" init-method="doStart">
<constructor-arg ref="consumerFactory"/>
<constructor-arg ref="containerProperties"/>
</bean>
</beans>

4.生产者测试类

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.kafka.core.KafkaTemplate;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/config/kafka-producer.xml" })
public class ProduceMessage {
@Autowired
private KafkaTemplate<Integer, String> kafkaTemplate;
@Test
public void testTemplateSend() {

//topic主题test是上篇http://www.cnblogs.com/Bud-blog/p/9020018.html中新建的主题名称
kafkaTemplate.send("test", "www.686868.com");
}
}

5.消费者监听消息

package com.kafka.service.impl;

import org.apache.kafka.clients.consumer.ConsumerRecord;
import org.springframework.kafka.listener.MessageListener;

/**
* 消费者监听
*
*/
public class MsgConsumerServiceImpl implements MessageListener<Integer, String>
{
public void onMessage(ConsumerRecord<Integer, String> record) {
System.out.println(record);
}
}

6.消费者测试类

import org.springframework.beans.BeansException;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class ConsumerTest {
public static void main(String[] args) {
try {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("config/kafka-consumer.xml");
context.start();
} catch (BeansException e) {
e.printStackTrace();
}

synchronized (ConsumerTest.class) {
while (true) {
try {
ConsumerTest.class.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
}

7.pom依赖如下：

8.项目视图

9.启动消费者测试类（注意：启动测试类前，需要启动zookeeper和kafka程序）

启动成功控制台如下显示

10.启动生产者测试类，启动成功控制台如下显示

9.consumer接收消息,控制台显示如下：
