java - 使用java套接字和HAPI的HL7消息解析错误

Question

我正在使用自动血液分析仪，它生成 HL7 消息并通过 TCP/IP 发送到连接的 PC。我正在使用 java 套接字来接收 HL7 消息/数据。但是当我尝试解析 HL7 消息(字符串)时，它显示错误消息:

ca.uhn.hl7v2.parser.EncodingNotSupportedException: Determine encoding for message.

以下是消息的前 50 个字符供引用，尽管这可能不是问题所在:

.MSH|^~\&|DH3x|Dymind|||20190421171520||ORU^R01|20`

我正在尝试使用 HAPI 解析消息

public static void main(String[] args) {

    try {
        //When using file
        //String messageString = readHL7MessageFromFileAsString(filePath);

        String messageString = ".MSH|^~\\&|DH3x|Dymind|||20190421171520||ORU^R01|20190421_140443_220|P|2.3.1||||||UNICODE\r\n" +

}

我期望消息对象。但输出给了我一条错误消息:

ca.uhn.hl7v2.parser.EncodingNotSupportedException: Determine encoding for message.

以下是消息的前 50 个字符供引用，尽管这可能不是问题所在:

.MSH|^~\&|DH3x|Dymind|||20190421171520||ORU^R01|20

Answer 1

我认为这是因为消息字符串中的前导点和尾随点。此外，您还有一个 ORU^R01 及其在同一消息字符串中的响应。这与点相结合可能会导致解析错误。

您可能需要显式调用 msh.getEncodingCharacters() 并检查其返回值(或检查异常堆栈跟踪)
