Marshalling an object that has object fields

java, jaxb, marshalling

Solution

`@XmlAttribute` on `registrationSource`, `@XmlValue` on `code`. Note that in this case you also should have `@XmlTransient` on other fields of `RegistrationSource`, such as `id`

EDIT: This works:

@XmlRootElement(name = "subscriptionRequest") 
public class RegistrationRequest { 

    private Long id; 
    private RegistrationSource registrationSource; 

    public Long getId() { return id; }
    public void setId(Long id) { this.id = id; }

    @XmlAttribute
    public RegistrationSource getRegistrationSource() { return registrationSource; }
    public void setRegistrationSource(RegistrationSource registrationSource)
    {
        this.registrationSource = registrationSource;
    }
}

public class RegistrationSource { 

    private Integer id; 
    private String code; 

    @XmlTransient
    public Integer getId() { return id; }
    public void setId(Integer id) { this.id = id; }

    @XmlValue
    public String getCode() { return code; }
    public void setCode(String code) { this.code = code; }
}

Problem

Not sure if the title makes any sense. I have an object that I want to marshal using JAXB that looks like this: ``` @XmlRootElement(name = "subscriptionRequest") public class RegistrationRequest { private Long id; private RegistrationSource registrationSource; } ``` The RegistrationSource object: ``` public class RegistrationSource { private Integer id; private String code; } ``` I want to create an xml that has the following layout: ``` <subscriptionRequest registrationSource="0002"> ... </subscriptionRequest> ``` where the registrationSource attribute value is the code field value from the RegistrationSource object. What xml annotations do I need to use?
