java - 当我多次使用相同的定位值时，骆驼绑定抛出空指针异常

Question

我正在为两个不同的属性使用两个具有相同位置的 DataField。它抛出空指针异常。任何人都可以帮助我如何使其工作。

* CamelRoute.java*

public class ConverterRoute implements RoutesBuilder {

    private static final String SOURCE_INPUT_PATH = "file://inbox?fileName=Source.txt";

    private static final String SOURCE_OUTPUT_PATH = "file://outbox?fileName=file_$simple{date:now:yyyyMMddHHmmssSSS}.xml";

    @Override
    public void addRoutesToCamelContext(CamelContext context) throws Exception {
        context.addRoutes(new RouteBuilder() {
            public void configure() {
                try {

                    DataFormat bindyFixed = new BindyCsvDataFormat(TestOne.class);

                    XmlFriendlyNameCoder nameCoder = new XmlFriendlyNameCoder("_-", "_");
                    Dom4JDriver dom4JDriver = new Dom4JDriver(nameCoder);

                    XStreamDataFormat xStreamDataFormat = new XStreamDataFormat();
                    xStreamDataFormat.setAliases(Collections.singletonMap("TEST_ONE", TestOne.class.getCanonicalName()));
                    //xStreamDataFormat.setXstreamDriver(dom4JDriver);

                    from(SOURCE_INPUT_PATH).
                            log("Received input from file and body is ${body}").
                            split().tokenize(System.lineSeparator()).
                            unmarshal(bindyFixed).
                            marshal(xStreamDataFormat).
                            log("After Marshalling and body is ${body}").
                            to(SOURCE_OUTPUT_PATH).log("Finished Transformation").
                      end();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }
}

TestOne.java

@CsvRecord(separator = "\\|", skipField = true)
public class TestOne{

    @DataField(pos = 3, required = true)
    private String testId;

    @Link
    private TestTwo testTwo;

}

测试二.java

@CsvRecord(separator = "\\|", skipField = true)
public class TestTwo{

    @DataField(pos = 3, required = true)
    private String mockIt;

}
