这就是我正在做的事情:
@XmlType(name = "foo")
@XmlAccessorType(XmlAccessType.NONE)
public final class Foo {
@XmlElement(name = "title")
public String title() {
return "hello, world!";
}
}
JAXB抱怨:
com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 2 counts of IllegalAnnotationExceptions
JAXB annotation is placed on a method that is not a JAXB property
this problem is related to the following location:
at @javax.xml.bind.annotation.XmlElement(nillable=false, name=title, required=false, defaultValue=, type=class javax.xml.bind.annotation.XmlElement$DEFAULT, namespace=##default)
at com.example.Foo
怎么办?我不希望(也不能)重命名该方法。

有几种不同的选择:
选项#1 - 介绍字段
如果值在示例中是常量,那么您可以在域类中引入一个字段并让JAXB映射到该字段:
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlType;
@XmlType(name = "foo")
@XmlAccessorType(XmlAccessType.NONE)
public final class Foo {
@XmlElement
private final String title = "hello, world!";
public String title() {
return title;
}
}
选项#2 - 介绍属性
如果计算了该值,那么您需要引入一个JavaBean访问器并将JAXB映射到该地址:
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlType;
@XmlType(name = "foo")
@XmlAccessorType(XmlAccessType.NONE)
public final class Foo {
public String title() {
return "hello, world!";
}
@XmlElement
public String getTitle() {
return title();
}
}

可能有更好的方法,但首先想到的解决方案是:
@XmlElement(name = "title")
private String title;
public String getTitle() {
return title();
}
为什么你不能根据Java惯例命名你的方法?
