这里如下这种

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxNzg0NDI3NjE_size_16_color_FFFFFF_t_70][]

不仅仅在Payload中可以放数据。在Properties的headers中也可以放数据。

其中basicPublish可以放properties，

其properties构造函数如下：

public BasicProperties(String contentType, String contentEncoding, Map<String, Object> headers, Integer deliveryMode, Integer priority, String correlationId, String replyTo, String expiration, String messageId, Date timestamp, String type, String userId, String appId, String clusterId) {
        this.contentType = contentType;
        this.contentEncoding = contentEncoding;
        this.headers = headers == null ? null : Collections.unmodifiableMap(new HashMap(headers));
        this.deliveryMode = deliveryMode;
        this.priority = priority;
        this.correlationId = correlationId;
        this.replyTo = replyTo;
        this.expiration = expiration;
        this.messageId = messageId;
        this.timestamp = timestamp;
        this.type = type;
        this.userId = userId;
        this.appId = appId;
        this.clusterId = clusterId;
    }
