spring boot中集成rabbitMQ启动报错

一直无线重启，测试方式用debug模式，程序能跑完，还是报错

一直报错找不到没有找到方法类

Sender代码
@Component
public class HelloSender {

@Autowired
private AmqpTemplate amqpTemplate;

public void send() {
    String context = "hello " + new Date();
    System.out.println("Sender : " + context);
    this.amqpTemplate.convertAndSend("hello", context);
}

Receiver代码
@Component
@RabbitListener(queues = "hello")
public class HelloReceiver {

@RabbitHandler
public void process(String hello) {

    System.out.println("Receiver  : " + hello);
}

}

config配置代码
@Configuration
public class RabbitConfig {

@Bean
public Queue helloQueue() {

    return new Queue("hello");
}

@Bean
public Queue neoQueue() {


    return new Queue("neo");
}

@Bean
public Queue objectQueue() {

    return new Queue("object");
}

}

测试代码
@RunWith(SpringRunner.class)
@SpringBootTest
public class HelloTest {

@Autowired
private HelloSender helloSender;

@Test
public void hello() throws Exception {
    helloSender.send();
}

}

@Component
@RabbitListener(queues = "object")
public class ObjectReceiver {

@RabbitHandler
public void process(User user) {

    System.out.println("Receiver object : " + user);
}

}

@Component
public class ObjectSender {

@Autowired
private AmqpTemplate amqpTemplate;

public void send(User user) {
    System.out.println("Sender object: " + user.toString());
    this.amqpTemplate.convertAndSend("object", user);
}

}

这是代码

HelloReceiver 类的注解使用有问题，----@RabbitListener 注解是方法级别的，不能用在class上。
正确的代码如下：

@Component

public class ObjectReceiver {

@RabbitListener(queues = "object")
@RabbitHandler
public void process(User user) {

System.out.println("Receiver object : " + user);

}

}

真的是 @RabbitListener 注解问题，我也写到class类上了，换到方法上果然ok 感谢~ :)

可能是实体没有序列化，实现序列化试试
