java - 如何编写具有属性和值的 JAXB 对象

Question

这是我想要的 XML 结构

<Outer type="good" id="1">
  <Uid>123</Uid>
  <Name>Myself</Name>
  <Inner type="bad">This Value</Inner>
</Outer>

这是我的对象。

@XmlAccessorType(XMLAccessType.FIELD)
@XmlType(name="Outer", propOrder = {
  "uid"
  "name"
  "inner"
})
public class Outer{
  @XmlElement(name = "Uid")
  protected String uid;
  @XmlElement(name = "Name")
  protected String name;
  @XmlElement(name = "Inner")
  protected Inner inner;

  public static class Inner{
    @XmlAttribute
    private String type;
    @XmlValue
    private String value;

    //setters & getters for both
  }

  //setters & getters for all the elements
}

现在我在类里面正在做

Outer o = new Outer();
o.setUid/ID/Type/Name() ; //all the setter
Inner i - new Inner();
i.setValue("This Value");
i.setType("bad");

当我运行这个时，我得到了

If a class has @XmlElement property, it cannot have @XmlValue property.

和

Class has two properties of the same name "type" (This one is for the Source class)

和

Class has two properties of the same name "value" (This one is for Source class too)

发生了什么事，我能做些什么来纠正这个问题？

谢谢

目前，JAXB 将两个字段(由于注释)和两对 get/set(由于默认访问器类型)作为属性进行威胁。所以你的类 Inner 有 4 个属性。

请为 Inner 类添加自己的访问器类型

   @XmlAccessorType(XmlAccessType.FIELD)
   public static class Inner
   {  

或者注释属性而不是字段

   public static class Inner
   {

      private String type;


      private String value;

      @XmlAttribute
      public String getType()
      {
         return type;
      }
      // setter setType

      @XmlValue
      public String getValue()
      {
         return value;
      }   
      // setter setValue
   }
