需要在 JAVA 中使用 HAPI 解析 HL7 消息

Question

我正在尝试使用 HAPI 解析 HL7 消息版本 2.8。在此之前，我能够从 MSH、EVN、PID、PV1 等每个细分市场中获取价值。但现在只从 MSH 段其他段（EVN、PId、PV1）获得价值为 NULL。请查看我的代码并为我提供解决方案。

public class ADTService {

    AWSCredentials awsCredentials = null;
    AmazonDynamoDBClient amazonDynamoDBClient = null; 

    public Reply sendADTMessage() throws HL7Exception {

        Reply reply = new Reply();
        PatientInfo patientInfo = new PatientInfo();

        byte[] valueDecoded= Base64.decode("TVNIfF5+XFwmfFNtYXJ0fDgwMDB8fEZ8MjAxMzA3MzExMzIyNTl8fEFEVF5BMDF8NDM0MzQzfFB8Mi44fHx8QUx8TkUKRVZOfFAwM3wyMDEzMDczMTEzMjI1OXx8T3x8MjAxMzA3MzExMzIyNTkKUElEfDF8UjQzNTQzNXxSNDM1NDM1fHxCQVRJU1RFXkFOVE9JTkVefHwxOTI1MDIyODAwMDAwMHxNfHx8fHx8fHx8fHw0MzgyNjEzMDcKUFYxfDF8SXxVLTAxXjQwN15BfHx8fHx8fHx8fHx8fHx8fHx8fHx8fHx8fHx8fHx8fHx8fHx8fHx8fHwyMDEwMTAwNTAwMDAwMA==");

        String decodedADT = new String(valueDecoded);
        System.out.println("Decoded value is " + decodedADT);

        HapiContext context = new DefaultHapiContext();
        context.setValidationContext(new NoValidation());

        try {

            Message hapiMsg = p.parse(decodedADT);
            System.out.println("Decoded value 1 is " + hapiMsg);

            ADT_A01 adtMsg = (ADT_A01)hapiMsg;

            MSH msh = adtMsg.getMSH();
            PID pid = adtMsg.getPID();

Answer 1

MSH/9/2 (A01) 中的事件触发器与 EVN/1 (P03) 中的事件类型代码不匹配。 MSH/9/3 中的消息结构丢失。
