JAXB在不创建子类的情况下取消标记子属性

我终于想出了如何做到这一点。 必须使用 @XmlJavaTypeAdapter 注释并将C类标记为 @XmlRootElement 以及一个 @XmlAccessorType(XmlAccessType.FIELD) . 此外,还需要使用 @XmlTransient 在用注释的字符串成员的getter上 @xmljavatypeadapter(XMLjavatypeadapter) .

全面解决方案:

C类:

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class C{
    @XmlValue
    private String c;

    @XmlAttribute
    private boolean someAttribute;
    //getters and setters for both

类适配器:

public class Adapter extends XmlAdapter<C, String> {

    public String unmarshal(C pC) throws Exception {
        //some possible handling with the attribute over pC.getSomeAttribute();
        return pC.getC();
    }

    public C marshal(String pC) throws Exception {
       C c = new C();
       c.setC(pC)
       //some possible handling to set the attribute to c
       return c;
    }

班家长:

public class Parent{
   private String a;
   private String b;
   @XmlJavaTypeAdapter(Adapter.class)
   private String c;

   @XmlTransient
    public String getC() {
        return c;
    }
   //getters and setters for b,a and setter for C
}
