CSDN今日推荐只要想学，什么时候都不晚！
JAVA使用JeasyOPC读取OPC 服务器数据
首先在src下新建包javafish.clients.opc 将JCustomOpc.properties 拷贝到包中， 然后导入三个jar包jeasyopc.jar commons-logging-1.1.jar和log4j-1.2.13.jar 在项目下新建一个lib目录，也可以自定义名字和路径，但是在JCustomOpc.properties 配置中能指定这个目录。将JCustomOpc.dll拷贝到 你定义好的目录下。写一个测试类，添加以下代码。[java]
确保自己机器已经运行了服务端。如图：JCustomOpc.properties 和JCustomOpc.dll 目录要准确，不然就容易报错找不到配置文件。
没有更多推荐了，只要是大神，都是我师傅
java 连接opc
第一种：用utgard连接opc，以下代码为官方的代码，改为自己的就可以了。&dependency&

}第二种：使用jOpc连接 opc服务器，只支持32位的package com.kaiya.svg.opc;

如果报这样的错：Property file javafish.clients.opc.JCustomOpc doesn't exist. System terminated那你就建立javafish.clients.opc这个文件夹，把JCustomOpc.properties
文件放入下面，文件内容如下在与src同目录下建立lib文件夹，放入JCustomOpc.dll
文件（自己下吧），当然你还需要jeasyopc.jar文件。难得写还是给你个链接吧: https://download.csdn.net/download/qq_65135
