一、前言
HL7协议相信医疗行业的IT人员都不陌生，笔者由于接触时间比较短，乍一听“协议”还是比较懵，不自觉就把它和“HTTP”、"SOAP”之类的网络协议挂上关联，可事实上这个HL7只是一种数据格式，传输方式也可以使用最简单的Socket。
二、正文
本文中用到的代码都做了部分敏感字删减，使用过程如遇到编译错误合理调整即可。
笔者调试中用到的工具及问题记录都会放到文末供大家参考。
1、环境配置
引入Maven依赖，笔者使用的hl7-2.6版本，所以只引入v26即可
<dependency><groupId>ca.uhn.hapi</groupId><artifactId>hapi-base</artifactId><version>2.3</version> <!-- 请根据实际情况选择最新版本 --></dependency><dependency><groupId>ca.uhn.hapi</groupId><artifactId>hapi-structures-v26</artifactId><version>2.3</version> <!-- 请根据实际情况选择最新版本 --></dependency>增加配置文件作为hl7协议单独配置
#是否开启监听 0-关闭、1-开启
hl7socket.server.flag=0
#端口号
hl7socket.server.port=30000
2、数据接收：HL7Monitor
使用JDK自带注解@PostConstrust作为初始化启动监听，直接使用依赖中封装的API即可，需要注意的是，可以将一些数据校验关闭，否则在接受过程中直接阻断消息接收。
启动监听服务仅需要端口号即可，另外要将接收数据后的业务处理类对象作为参数传入registerApplication方法。

}3、数据解析：HL7Business
数据解析和数据处理在一起，笔者这边的业务是将数据接收到后解析出来，直接使用websocket推送给前端，前端会将接收到的数据echart渲染到页面，例如：各个波形图、检测数值等都会实时展示。

}三、总结
1、工具分享
笔者使用的是：7Edit 可以模拟发送hl7协议数据用于Socket调试使用，具体用法可以参考其他博主的文章，本来想截几个工具的图片，但是试用期已过不让打开了......
调试过程中可以用上述工具观察解析结果，但是要大规模，大密度模拟报文就需要手动写几个测试类调用了，下述是笔者测试中用到的工具类，分享给大家。

笔者在开发中遇到的最坑的一个问题，也是耽误时间最长的：
从日志中抓取到hl7传输的数据，作为字符串复制到代码中开始调试，但是无论怎么运行都只能获取到第一行的部分数据，经过反反复复的调整环境仍然无果。
最后无意中看到了字符串末尾 \n 的字符，这才想到可能是换行导致了API识别有误，替换为 \r 后解析就正常啦。
以后也要注意粘贴进来的换行符可能会影响到解析逻辑。
