1、添加Maven依赖 (或jar包)

<!-- RabbitMQ --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-amqp</artifactId></dependency>

2、配置数据源相关信息

#RabbitMQspring.application.name=spirng-boot-rabbitmqspring.rabbitmq.host=192.168.10.15spring.rabbitmq.port=5672spring.rabbitmq.username=adminspring.rabbitmq.password=admin

3、接受者

import org.springframework.amqp.rabbit.annotation.RabbitHandler;import org.springframework.amqp.rabbit.annotation.RabbitListener;import org.springframework.stereotype.Component;import com.cl.model.User;@Component@RabbitListener(queues = "userQueue")public class HelloReceiver {// 接受者@RabbitHandlerpublic void process(User user) {System.out.println("Receiver object : " + user);}}

4、发送者

import org.springframework.amqp.core.AmqpTemplate;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;import com.cl.model.User;@Componentpublic class HelloSender {@Autowiredprivate AmqpTemplate rabbitTemplate;// 发送者public void send(User user) {System.out.println("Sender object: " + user.toString());this.rabbitTemplate.convertAndSend("userQueue", user);}}

5、Bean对象

import java.io.Serializable;public class User implements Serializable {private static final long serialVersionUID = -347894033089232321L;private Integer id;private String username;private String password;private String email;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getUsername() {return username;}public String getEmail() {return email;}public void setEmail(String email) {this.email = email;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}@Overridepublic String toString() {return "User [id=" + id + ", username=" + username + ", password=" + password + ", email=" + email + "]";}}

6、测试

@RunWith(SpringJUnit4ClassRunner.class)@SpringBootTest(classes = Application.class) // 指定spring-boot的启动类@WebAppConfigurationpublic class TestRabbiMq {@Autowiredprivate HelloSender helloSender;@Testpublic void oneToMany() throws Exception {User user = new User();user.setEmail("clypm@126.com");user.setPassword("123456");helloSender.send(user);}}

7、异常处理

org.springframework.amqp.rabbit.listener.BlockingQueueConsumer$DeclarationException: Failed to declare queue(s):[userQueue]at org.springframework.amqp.rabbit.listener.BlockingQueueConsumer.attemptPassiveDeclarations(BlockingQueueConsumer.java:587) ~[spring-rabbit-1.6.1.RELEASE.jar:na]at org.springframework.amqp.rabbit.listener.BlockingQueueConsumer.start(BlockingQueueConsumer.java:486) ~[spring-rabbit-1.6.1.RELEASE.jar:na]at org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer$AsyncMessageProcessingConsumer.run(SimpleMessageListenerContainer.java:1280) [spring-rabbit-1.6.1.RELEASE.jar:na]at java.lang.Thread.run(Thread.java:745) [na:1.8.0_121]Caused by: java.io.IOException: nullat com.rabbitmq.client.impl.AMQChannel.wrap(AMQChannel.java:106) ~[amqp-client-3.6.3.jar:na]at com.rabbitmq.client.impl.AMQChannel.wrap(AMQChannel.java:102) ~[amqp-client-3.6.3.jar:na]at com.rabbitmq.client.impl.AMQChannel.exnWrappingRpc(AMQChannel.java:124) ~[amqp-client-3.6.3.jar:na]at com.rabbitmq.client.impl.ChannelN.queueDeclarePassive(ChannelN.java:885) ~[amqp-client-3.6.3.jar:na]at com.rabbitmq.client.impl.ChannelN.queueDeclarePassive(ChannelN.java:61) ~[amqp-client-3.6.3.jar:na]at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[na:1.8.0_121]at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[na:1.8.0_121]at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[na:1.8.0_121]at java.lang.reflect.Method.invoke(Method.java:498) ~[na:1.8.0_121]at org.springframework.amqp.rabbit.connection.CachingConnectionFactory$CachedChannelInvocationHandler.invoke(CachingConnectionFactory.java:916) ~[spring-rabbit-1.6.1.RELEASE.jar:na]at com.sun.proxy.$Proxy89.queueDeclarePassive(Unknown Source) ~[na:na]at org.springframework.amqp.rabbit.listener.BlockingQueueConsumer.attemptPassiveDeclarations(BlockingQueueConsumer.java:566) ~[spring-rabbit-1.6.1.RELEASE.jar:na]... 3 common frames omittedCaused by: com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=404, reply-text=NOT_FOUND - no queue 'userQueue' in vhost '/', class-id=50, method-id=10)at com.rabbitmq.utility.ValueOrException.getValue(ValueOrException.java:67) ~[amqp-client-3.6.3.jar:na]at com.rabbitmq.utility.BlockingValueOrException.uninterruptibleGetValue(BlockingValueOrException.java:33) ~[amqp-client-3.6.3.jar:na]at com.rabbitmq.client.impl.AMQChannel$BlockingRpcContinuation.getReply(AMQChannel.java:361) ~[amqp-client-3.6.3.jar:na]at com.rabbitmq.client.impl.AMQChannel.privateRpc(AMQChannel.java:226) ~[amqp-client-3.6.3.jar:na]at com.rabbitmq.client.impl.AMQChannel.exnWrappingRpc(AMQChannel.java:118) ~[amqp-client-3.6.3.jar:na]... 12 common frames omitted

说明RabbitMQ中没有找到该队列，添加一个就OK
