问题描述

我有一个MyBean注释

I have a MyBean annotated

@XmlRootElement
public class MyBean ...

编组/取消编组MyBean w / o问题，例如

Marshalling/Unmarshalling MyBean w/o problems, e.g.

JAXBContext jaxbCtx = JAXBContext.newInstance(MyBean.class);
Marshaller m = jaxbCtx.createMarshaller();
m.marshal(myBean, writer);

如何使用JAXB来编组/取消编组集合或列表？

How can I use JAXB to marshall/unmarshall a Collection or List?

我的尝试会导致此错误：

My attempt results in this error:

javax.xml.bind.MarshalException
 - with linked exception:
[com.sun.istack.internal.SAXException2: unable to marshal type "java.util.ArrayList" as an element because it is missing an @XmlRootElement annotation]
    at com.sun.xml.internal.bind.v2.runtime.MarshallerImpl.write(MarshallerImpl.java:304)
    at com.sun.xml.internal.bind.v2.runtime.MarshallerImpl.marshal(MarshallerImpl.java:230)

推荐答案

c $ c> MyBeanList 并使用它。与SO相关的内容使用JAXB取消/编组列表< String>

You have to create another element of type MyBeanList and use it. Something related on SO Using JAXB to unmarshal/marshal a List<String>
