使用Spring AMQP“无法转换类型的值”异常

我正在尝试向RabbitMQ服务器上的直接交换发送消息 .

我将队列命名为“test_queue”并使用同名“test_queue”进行直接交换，该命令绑定到队列“”test_queue“ .

我使用带有XML配置的Spring AMQP与Rabbit MQ进行交互，这是我的conf：

<rabbit:template id="amqpTemplate"
                 connection-factory="rabbitConnectionFactory"
                 exchange="test_queue"/>

<rabbit:admin connection-factory="rabbitConnectionFactory"/>

<rabbit:queue name="test_queue"/>

<rabbit:connection-factory id="rabbitConnectionFactory" (...)/>

<rabbit:direct-exchange name="test_queue">
    <rabbit:bindings>
        <rabbit:binding queue="test_queue"/>
    </rabbit:bindings>
</rabbit:direct-exchange>

而我正试图以这种方式发送消息：

AbstractApplicationContext ctx = new ClassPathXmlApplicationContext("context.xml");
RabbitTemplate template = (RabbitTemplate) ctx.getBean("amqpTemplate");
template.convertAndSend("Hello, world!");

我得到的例外情况：
