如何解决ObjectToJsonTrasnformer with Spring RabbitMq (spring boot 2.5.0) 在 bean 创建时抛出 java.lang.VerifyError: Bad return type
我有一个通过rabbitmq 进行通信的微服务。 它的pom如下：

RabbitMqConfiguration 在@Configuration 类中配置：
@Bean
public ConnectionFactory connectionFactory() {
com.rabbitmq.client.ConnectionFactory connectionFactoryClient = new com.rabbitmq.client.ConnectionFactory();
connectionFactoryClient.setUsername(username);
connectionFactoryClient.setPassword(password);
connectionFactoryClient.setHost(hostname);
connectionFactoryClient.setVirtualHost(vhost);
return new ThreadChannelConnectionFactory(connectionFactoryClient);}
@Bean
@Primary
public RabbitTemplate rabbitTemplateAdapter(ConnectionFactory connectionFactory) {
RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
rabbitTemplate.setMandatory(true);
return rabbitTemplate;
}
我还在 AppConfiguration 类中定义了 ObjectToJsonTransformer 和 JsonToObjectTransformer bean：
@Bean
public ObjectToJsonTransformer objectToJsonTransformer() {
return new ObjectToJsonTransformer();
}
@Bean
public JsonToObjectTransformer jsonToObjectTransformer() {
return new JsonToObjectTransformer();
}
我有一个使用 ObjectToJsonTransformer 的 @Component 类：
public class RabbitMessageService {
private final RabbitTemplate rabbitTemplateAdapter;
private final ObjectToJsonTransformer objectToJsonTransformer;
public void messageTransforming(Message<?> message) {
Message<?> jsonMessage = objectToJsonTransformer.transform(message);
try {...}
}
....}
问题是，当我将其部署到 Cloud Foundry（版本 6.46.0+29d6257f1.2019-07-09）时，出现以下错误：

在 pom.xml 中，我还使用了 roder 中的 spring-boot-starter-data-redis-reactive 依赖项来将有效负载保存在 redis 中。
我认为这可能是依赖项之间的冲突？ 我不知道如何绕过这个。
