BACnet/IP之BACnet4j学习java代码例子属性读写01

   第一次接触BACnet ip，开发语言使用java，网上搜了下，都是推荐使用BACnet4j，但是找不到完整的demo，折腾了一段时间，勉强跑通了自己写的demo，读取到的设备模拟器上的数据。

1.下载Yabe设备模拟器

  链接: https://pan.baidu.com/s/1OK1uq-tfU-XoOH10h4Otag 提取码: 4eu4

安装后

打开太阳的图标

这是设备模拟器，Yabe还提供了一个客户端，打开放大镜图标

可以在client端看到相关的数据信息。

2.下载BACnet4j

https://github.com/infiniteautomation/BACnet4J

下载需要的版本，本博文的代码使用的是5.0.2版本，然后本地安装 mvn install -Dmaven.test.skip=true

3.写demo代码

创建maven项目,pom.xml引入BACnet4j(上面下载安装的）,比如

	
	
		com.infiniteautomation
	    bacnet4j
	    5.0.2
	

注意：1.Yabe和代码在同一台电脑少，跨网段的话暂时不知道该怎样解决。

           2.运行代码的时候，必须先关闭Yabe的客户端（explorer)，否则代码会提示地址被占用了

注意：修改的话，必须是设备端运行被修改的才行，否则会报异常，拒绝写。可以使用Yabe的客户端(expoler)进行测试确认哪个只能被修改.
