Spring boot 使用rabbitmq消息时，getting method not found异常

已在使用者类上创建以使用来自rabbitMQ GUI的消息

但是，当我从rabbitMQ GUI发布任何消息时，找不到它的给定错误类。控制台上不断打印错误

问题可能是rabbitGUI以字节的形式发送消息，而我正试图以字符串形式接收它

我想调用基于消息体的特定方法

@组件
@RabbitListener（队列={“#{addNeRangeQueue.name}}”）
公共类消费控制器{
@猎兔人
公共无效接收（字符串消息）{
System.out.println（“兔子mq侦听器接收：+消息”）；
}
}
@配置
公共类RabbitMQConsumerConfig{
//我在这里删除的属性值配置。
@豆子
公共队列addNeRangeQueue（）{
返回新队列（queueName，false）；
}
@豆子
公共TopiceExchange getTopicEchangeName（）{
返回新的TopiceExchange（exchange）；
}
@豆子
公共绑定bindaddNeRange（TopiceExchange getTopicEchangeName，Queue addNeRangeQueue）{
返回BindingBuilder.bind（addNeRangeQueue）.to（getTopicEchangeName）.with（routingkey）；
}
}

例外情况：

从UI发布时，必须添加

内容类型

属性，以便消息转换器知道将

字节[]

消息正文转换为什么

使用方法级

@RabbitListener

，转换器可以从方法参数推断类型-这在类级注释中是不可能的，因为我们需要先进行转换以确定调用哪个方法

对于默认值为

SimpleMessageConverter

的简单字符串：

当使用JSON（以及

Jackson2JsonMessageConverter

）时：

谢谢，是的，我使用Jackson2JsonMessageConverter转换来自rabbitMQ GUI的消息，但效果不理想。
