编组具有对象字段的对象

Question

不确定标题是否有意义.我有一个对象,我想使用看起来像这样的JAXB编组:

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

    private Long id;
    private RegistrationSource registrationSource;
    }

RegistrationSource对象:

 public class RegistrationSource {

    private Integer id;
    private String code;
}

我想创建一个具有以下布局的xml:

<subscriptionRequest registrationSource="0002">
    ...
</subscriptionRequest>

其中registrationSource属性值是RegistrationSource对象的代码字段值.

我需要使用哪些xml注释？

Answer 1

@XmlAttributeon registrationSource,@XmlValueon code.请注意,在这种情况下,您还应该具有@XmlTransient其他字段RegistrationSource,例如id

编辑:这工作:

@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; }
}
