terser之后的HAPI v2：获取完整的更改消息

时间：2017-02-20 23:02:55

标签： hapi

我有一条HL7消息，其内容我正在使用 terser.set（）方法稍微操作。一旦我完成了这个，我在调试器中看到它已经被改变了我想要它，但我似乎无法完整地回复整个消息。我试过（例如）：

HapiContext context = new DefaultHapiContext();
Parser      parser  = context.getGenericParser();
Message     message = parser.parse( MESSAGE );
Terser      terser  = new Terser( message );

terser.set( "/PID-2", "XXX XX XXXX" );

String fixedMessage = message.encode();

...让我靠近，然而，在垂直条（管道）中结束但在其字段中没有值的行（段线）会被修剪（垂直条被简单地删除）。我希望消息与我输入的内容保持一致（如果我也故意修改了它）。

我认为你需要在ParserConfiguration中使用addForcedEncode。

        ExecutorService es = hc.getExecutorService(); // to avoid npe when closing context should be fixed https://sourceforge.net/p/hl7api/bugs/223/
        ParserConfiguration pc = hc.getParserConfiguration();
        PipeParser pipeParser = hc.getPipeParser();
        Message message = pipeParser.parse(m);
        Terser terser = new Terser(message);
        //Add first Address
        terser.set("/.PID-11(0)-1", "13 Oxford Road");

        terser.set("/.PID-11(1)-1", "16 London Road");
        terser.set("/.PID-11(1)-3", "London");

        pc.addForcedEncode("PID-26-1"); // make sure PID has 26 fields
        System.out.println(message.encode().replaceAll("\r", "\r\n"));
        hc.close();
    } catch (HL7Exception e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

从技术上讲，您不是更改消息，您将其解析为Java对象并将其编码回字符串。这样输出消息就像输入消息一样。之后可能仍然存在细微的差异（例如，如果您的输入消息是动态的）。

来自文档（http://hl7api.sourceforge.net/configuring_hapi.html）：

强制编码

默认情况下，在对邮件进行编码时，HAPI不会对没有内容的任何段或字段进行编码，因此在邮件中没有语义含义。

如果您需要将消息传输到期望存在某些空内容的系统，以便获得有关消息中所在位置的“提示”，则会导致问题。

addForcedEncode方法可用于添加应强制编码的Terser路径：

parser.getParserConfiguration（）addForcedEncode（ “PATIENT_RESULT / ORDER_OBSERVATION / ORC-4”）。 //即使ORC没有内容，ORC-4仍然存在（但是为空） String encoded = parser.encode（message）; 有关示例，请参阅JavaDoc。
