Java 有没有办法用JaxB将一个类包装在另一个类中的elementwrapper？

我试图从xml中获得一个输出，它需要对我已经拥有的类进行包装。但我无法包装这些元素

我已经尝试过

@xmlementwrapper

这个类，也尝试过以某种方式嵌套，但都没有成功

这是我的地址类

@XmlRootElement(name="v41:address")
public class Address {
    private String street;
    private String housenr;
    private String zip;
    private String city;

    public Address(String street, String housenr, String zip, String city) {
        setStreet(street);
        setHousenr(housenr);
        setZip(zip);
        setCity(city);
    }

    public Address(){

    }


    @XmlElement(name = "v41:street")
    public String getStreet() {
        return street;
    }

    public void setStreet(String street) {
        this.street = street;
    }

    @XmlElement(name = "v41:houseNr")
    public String getHousenr() {
        return housenr;
    }

    public void setHousenr(String housenr) {
        this.housenr = housenr;
    }

    @XmlElement(name = "v41:zip")
    public String getZip() {
        return zip;
    }

    public void setZip(String zip) {
        this.zip = zip;
    }

    @XmlElement(name = "v41:city")
    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    @Override
    public String toString() {
        return "Address{" +
                "street='" + street + '\'' +
                ", housenr=" + housenr +
                ", zip=" + zip +
                ", city='" + city + '\'' +
                '}';
    }
}

这是我的请求类

@XmlRootElement(name="v41:request")
public class WSGRequest {
    private String ispId;

    private String contrEleId;

        setBbType(bbType);
        setDnType(dnType);

    }

    public WSGRequest() {

    }

    @XmlAttribute

    }

    public void setBbType(String bbType) {
        this.bbType = bbType;
    }

    @XmlElement(name = "v41:dnType")
    public String getDnType() {
        return dnType;
    }

    public void setDnType(String dnType) {
        this.dnType = dnType;
    }

    @XmlElement(name = "v41:qualifExtRef")
    public String getQualifExtRef() {
        return qualifExtRef;
    }

    public void setQualifExtRef(String qualifExtRef) {
        this.qualifExtRef = qualifExtRef;
    }



    @Override

这是我在“主”部分的代码的一部分

我想要的是一个字符串，它包含我上面发布的XML调用，可能在构造函数中有一个Address对象。

在您的

WSGRequest

类中当前没有

Address

字段，您到底尝试了什么？有，但它们像注释，因为否则代码会给我一个错误。我尝试过XmlElementWrapper类，但没有成功。我还尝试将make Address作为WSGRequest（地址类的getter）中的一个XmlElement。现在为了避免这个问题，我将把地址字段放在WSGRequest中，但不是作为类，而是作为字段。但这不是我想要的工作方式，这将是太多的硬代码和静态。我已经解决了这个问题。我刚刚使用索引of和子字符串将address类生成的XML插入请求中。：）

public static String requestJaxObjectToXML(WSGRequest request){
        try{
            //CREATE JAXB Context
            JAXBContext jaxbContext = JAXBContext.newInstance(WSGRequest.class);

            //Create Marshaller
            Marshaller jaxbMarshaller = jaxbContext.createMarshaller();

            /*Required Formatting?*/
            jaxbMarshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
            jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
            jaxbMarshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);

            //Print XML String to Console
            StringWriter sw = new StringWriter();
            //Write XML to Stringwriter
            jaxbMarshaller.marshal(request, sw);

            String xmlContent = sw.toString();

            return xmlContent;
        }
        catch(JAXBException e){
            //return e.getCause().toString();
            return "ERROR!";


        }
    }

 WSGRequest request = new WSGRequest("100032", "true", "110", "100", "2", "1", "#myTicId", "test");
        String completeRequest = requestJaxObjectToXML(request);
