我有管道分隔的数据，我想将其转换为 xml。该转换需要根据管道分隔数据的内容来完成。我正在尝试应用工厂设计模式来设计我的模型类。它会引发以下错误。

解决基于内容的转换问题的最佳方法是什么。

PartIfd.java

    @DataField(pos = 3)
    private Integer WHSID;

    @Link
    private CntrlSeg cntrlSeg;

}

CntrlSeg.java

public class CntrlSeg {

    @DataField(pos = 5)

}

PartIfdFactory.java

        if(string.equals("03000")){
            return new PartSeg3000();
        }else 
            return new PartSeg3030();
    }

PartSeg.java

public interface PartSeg {
    public void recordNum();

PartSeg3000.java

public class PartSeg3000 implements PartSeg {

    private Integer recordNum;

    @Override
    public void recordNum() {
        System.out.println("3000");

PartSeg3030.java

public class PartSeg3030 implements PartSeg {

    private Integer recordNum;

    @Override
    public void recordNum() {

转换器路由.java
