DETAIL: ELEMENT

javax.xml.bind.annotation Annotation Type XmlAnyAttribute

@Retention(value=RUNTIME) @Target(value={FIELD,METHOD}) public @interface XmlAnyAttribute

Implements: Annotation

@Retention(value=RUNTIME)
@Target(value={FIELD, METHOD})

将 JavaBean 属性映射到通配符属性的映射表中。

用法

@XmlAnyAttribute 注释可以与以下程序元素一起使用：

JavaBean 属性
非 static、非 transient 字段

有关其他公共信息，请参阅 javax.xml.bind.package javadoc 中的“包规范”。

用法受到以下约束的限制：

最多只能使用 @XmlAnyAttribute 注释类中的一个字段或属性。
属性或字段的类型必须是 java.util.Map。

在处理将解组成为一个值类的属性时，与另一个 JavaBean 属性不存在静态关联的（通过 XmlAttribute）每个属性都被输入 Map<QName,Object> 表示的通配符属性映射表中。属性 QName 是映射表的键。键值是属性的字符串值。

英文文档：

Maps a JavaBean property to a map of wildcard attributes.

Usage

The @XmlAnyAttribute annotation can be used with the following program elements:

JavaBean property
non static, non transient field

See "Package Specification" in javax.xml.bind.package javadoc for additional common information.

The usage is subject to the following constraints:

At most one field or property in a class can be annotated with @XmlAnyAttribute.
The type of the property or the field must java.util.Map

While processing attributes to be unmarshalled into a value class, each attribute that is not statically associated with another JavaBean property, via XmlAttribute, is entered into the wildcard attribute map represented by Map<QName,Object>. The attribute QName is the map's key. The key's value is the String value of the attribute.
