JSON.toJSONString(obj);//会将date变成时间戳。JSON.toJSONStringWithDateFormat(obj,"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");//继续保存为时间戳
报错的原因：1.查到的字段值是时间戳，而接收类型是date；2.查到的字段值是时间戳（毫秒），而gson默认转换秒值；可以通过自行对日期进行反序列化，兼容解析各种日期格式：import com.google.gson.JsonDeserializationContext;import com.google.gson.JsonDeserializer;import com.google.gson.J
fanout它会把所有发送到该交换器的消息路由到所有与该交换器绑定的队列中direct它会把消息路由到那些BingingKey 和RoutingKey完全匹配的队列中topic和direct类似，比其更灵活，支持通配符匹配
