使用杰克逊的XmlMapper
,有没有办法让对象列表的元素名称与localName
中给出的@JacksonXmlRootElement
相匹配?
例如,给定以下类
interface Foo {}
@JacksonXmlRootElement(localName = "bar")
class Bar implements Foo {}
@JacksonXmlRootElement(localName = "baz")
class Baz implements Foo {}
@JacksonXmlRootElement(localName = "container")
class FooContainer {
@JacksonXmlElementWrapper(useWrapping = false)
private List<Foo> foos;
FooContainer(List<Foo> foos) {
this.foos = foos;
}
public List<Foo> getFoos() {
return foos;
}
}
使用XmlMapper
FooContainer container = new FooContainer(Arrays.asList(new Bar(), new Baz()));
XmlMapper xmlMapper = new XmlMapper();
xmlMapper.writeValueAsString(container);
我们获得以下XML
<container>
<foos/>
<foos/>
</container>
有没有办法取而代之?
<container>
<bar/>
<baz/>
</container>
答案 0 :(得分:0)
我无法在杰克逊找到这样做的方法,但在JAXB中这几乎是微不足道的。

解组:
interface Foo {}
class Bar implements Foo {}
class Baz implements Foo {}
@XmlRootElement(name = "container")
@XmlAccessorType(XmlAccessType.FIELD)
class FooContainer {
@XmlElements({
@XmlElement(name = "bar", type = Bar.class),
@XmlElement(name = "baz", type = Baz.class)
})
private List<Foo> foos;
FooContainer() {}
FooContainer(List<Foo> foos) {
this.foos = foos;
}
public List<Foo> getFoos() {
return foos;
}
}
