java - @XmlAttribute 显示为 @XmlElement

Question

在我的网络服务上，我将变量定义为@XmlAttribute:

@XmlAttribute
protected String domain;

但是当我通过 SoapUi 进行查询时，它显示为 XML 元素:

<ns:domain>domain</ns:domain>

我在代码中找不到任何错误..

如何解决这个问题？

您在字段上显示注释，但 JAXB 默认使用属性(getter/setter 方法)访问。您是否更改了 JAXB 的默认访问权限？尝试将注释放在 getter 方法上。

编辑:由于您似乎遇到了麻烦，这里有一个可执行示例:

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.annotation.*;
import java.io.StringWriter;

public static void main(String[] args) throws Exception {
    Foo foo = new Foo("my attribute value", "my element value");
    Marshaller marshaller = JAXBContext.newInstance(Foo.class).createMarshaller();
    StringWriter stringWriter = new StringWriter();
    marshaller.marshal(foo, stringWriter);
    System.out.println(stringWriter);
}

@XmlRootElement
static class Foo {
    private String anAttribute;
    private String anElement;

    Foo() {}

    public Foo(String anAttribute, String anElement) {
        this.anAttribute = anAttribute;
        this.anElement = anElement;
    }

    @XmlAttribute
    public String getAnAttribute() { return anAttribute; }
    @XmlElement
    public String getAnElement() { return anElement; }
}

输出(格式化):

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<foo anAttribute="my attribute value">
    <anElement>my element value</anElement>
</foo>
