                        //创建一个发送的消息对象

                        //给这个对象赋实际的消息
                        TxtMsg.Text = Msg.ToJson();
                        //设置消息对象的属性，这个很重要哦，是Queue的过滤条件，也是P2P消息的唯一指定属性
                        //生产者把消息发送出去，几个枚举参数MsgDeliveryMode是否长链，MsgPriority消息优先级别，发送最小单位，当然还有其他重载
                        MsgProducer.Send(TxtMsg, MsgDeliveryMode.NonPersistent, MsgPriority.Normal, TimeSpan.MinValue);

问题

1. 查看消息显示： Error!  Exception occurred while processing this request, check the log for more information!

原因： 安装了 JRE8 ， 改到 JRE7！
