Question

我正在使用骆驼绑定来实现解析器。我有很多事件的固定长度记录。

因此，我尝试使用分离器解析此记录。

我认为FixedLengthFormat类可以处理页眉和页脚。因此，我在Body Dataformat类中定义了以下代码。

@FixedLengthRecord(length = 20, header=VoLTEHeader.class, footer=VoLTEFooter.class)

但是我发现下面的异常。请检查此问题。

**路由器**

    public static class ContextConfig extends RouteBuilder {
         DataFormat bindyHeader = new BindyFixedLengthDataFormat(VoLTEHeader.class);
         DataFormat bindyTailer = new BindyFixedLengthDataFormat(VoLTEFooter.class);
         DataFormat bindyOneBody = new BindyFixedLengthDataFormat(VoLTEBody.class);

       @Override
    public void configure() throws Exception {
        from(URI_DIRECT_START)
        .setBody().groovy("request.body.split('(?<=\\\\G.{20})')
                    .split(body(), AggregationStrategies.flexible().storeInHeader("bodyList").accumulateInCollection(ArrayList.class))
                       .unmarshal(bindyOneBody)
                    .end()
                    .to(URI_MOCK_RESULT);
            }

**测试**

    @Test
@DirtiesContext
public void testUnMarshallMessage() throws Exception {
            String URI_DIRECT_START = "direct:start";
    String records = "1VOLTE20190515     32010123456782019051520101234567820190516201012345678201905173AAAA.DAT           ";
            template.sendBody(URI_DIRECT_START, aaa);

**数据格式**

@FixedLengthRecord(length = 20, paddingChar = ' ')
public class VoLTEHeader {
     @DataField(pos = 1, length = 1, trim = true)
     String record_type;

     @DataField(pos = 2, length = 5, trim = true)
     String service_type;

     @DataField(pos = 7, length = 8, trim = true)
     String creation_date;

     @DataField(pos = 15, length = 6, trim = true, align = "R")
     String custom_flag;

     @Override
     public String toString() {
          return String.format("VoLTEHeader[record_type=%s, service_type=%s, creation_date=%s, custom_flag=%s]", record_type, service_type, creation_date, custom_flag);
       }
}

@FixedLengthRecord(length = 20, header=VoLTEHeader.class, footer=VoLTEFooter.class)
public class VoLTEBody {
    @DataField(pos = 1, length = 1, trim = true)
    String record_type;

    @DataField(pos = 2, length = 11, trim = true)
    String mobile_number;

    @DataField(pos = 13, length = 8, trim = true)
    String call_start_date;

    @Override
    public String toString() {
          return String.format("VoLTEBody[record_type=%s, mobile_number=%s, call_start_date=%s]", record_type, mobile_number, call_start_date);
    }
}

@FixedLengthRecord(length = 20, paddingChar = ' ')
public class VoLTEFooter {
    @DataField(pos = 1, length = 1, trim = true)
    String record_type;

    @DataField(pos = 2, length = 19, trim = true)
    String file_name;

    @Override
    public String toString() {
         return String.format("VoLTEFooter[record_type=%s, file_name=%s]", record_type, file_name);
    }
}

如何处理拆分器的此问题？
