@Configuration
public class RabbitConfig {
@Bean
public Queue Queue() {
return new Queue("hello");
}
}

rabbitTemplate是springboot 提供的默认实现
public class HelloSender {
@Autowired
private AmqpTemplate rabbitTemplate;
public void send() {
String context = "hello " + new Date();
System.out.println("Sender : " + context);
this.rabbitTemplate.convertAndSend("hello", context);
}
}

@Component
@RabbitListener(queues = "hello")
public class HelloReceiver {
@RabbitHandler
public void process(String hello) {
System.out.println("Receiver : " + hello);
}
}

@RunWith(SpringRunner.class)
@SpringBootTest
public class RabbitMqHelloTest {
@Autowired
private HelloSender helloSender;
@Test
public void hello() throws Exception {
helloSender.send();
}
}

@Test
public void oneToMany() throws Exception {
for (int i=0;i<100;i++){
neoSender.send(i);
}
}

@Test
public void manyToMany() throws Exception {
for (int i=0;i<100;i++){
neoSender.send(i);
neoSender2.send(i);
}
}

//对象的支持
//springboot以及完美的支持对象的发送和接收，不需要格外的配置。
//发送者
public void send(User user) {
System.out.println("Sender object: " + user.toString());
this.rabbitTemplate.convertAndSend("object", user);
}
...
//接受者
@RabbitHandler
public void process(User user) {
System.out.println("Receiver object : " + user);
}
