Java Spring Cloud Stream 2.0 ClassNotFoundException用于自定义标头

升级到Spring Cloud Stream Elmhurst.RELEASE后，@StreamListener方法在使用带有自定义头对象HttpHeaders的消息时抛出错误

发布者方法：

public static <T> Message<T> getMessage(T payload, HttpHeaders httpHeaders) {
    MessageHeaderAccessor accessor = new MessageHeaderAccessor();
    accessor.copyHeaders((Map)httpHeaders.entrySet().stream().filter((x) -> {
        return !((String)x.getKey()).equalsIgnoreCase("correlationid");
    }).collect(Collectors.toMap(Entry::getKey, Entry::getValue)));
    accessor.setHeader("httpHeaders", httpHeaders);
    return MessageBuilder.withPayload(payload).setHeaders(accessor).build();
}

@StreamListener(INPUT_CHANNEL)
public void handleMessage(@Payload CustomObject request, @Header(name = "httpHeaders") HttpHeaders httpHeaders) {

    //handling
}

使用消息后stacktrace出错：

这很可能是由于Web和执行器是可选的依赖项，因为2.0-

也要记住，

org.springframework.http.HttpHeaders

只是一个

多值映射。因此，您可能不需要担心这种依赖关系，只需要依赖它的超级类。抱歉，我的回复太晚了，但我已经在依赖关系中添加了spring boot starter启动器和spring boot starter web
