修改后的v2 :获取全部更改的消息

Question

我有一条HL7消息，它的内容是我用terser.set()方法稍微操作的。一旦我这样做了，我在调试器中看到它已经被改变了，这正是我想要的，但我似乎无法完整地得到整个消息。我尝试过(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();

然而，...which让我更接近了，但是，以垂直条(管道)结尾的行(段行)在其字段中没有值的情况下回来了(垂直条被简单地删除了)。我希望这条信息与我输入的内容保持一致(如果我也是故意修改的话)。

我认为您需要在addForcedEncode中使用ParserConfiguration。

        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)-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，您不是在更改消息，而是将其解析为Java并将其编码回string。这样，输出消息就像输入消息一样。之后仍然可能存在细微的差异(例如，如果您的输入消息是动态的)。

来自docs (hapi.html)：

强制编码

默认情况下，在编码消息时，HAPI不会对没有内容因而在消息中没有语义意义的任何段或字段进行编码。

如果您需要将一条消息发送到一个希望出现某些空内容的系统，以便获得关于消息中的位置的“提示”，这可能会导致问题。

addForcedEncode方法可用于添加应该强制编码的Terser路径：

parser.getParserConfiguration().addForcedEncode("PATIENT_RESULT/ORDER_OBSERVATION/ORC-4")；// ORC-4仍然存在(但为空)，即使ORC没有内容字符串编码=parser.encode(消息)；有关示例，请参见JavaDoc。
