解组单个元素列表失败 [英] Unmarshal a single element list fails
问题描述
我在Glassfish 3上的 Blaise Doughans博客上运行了一个样本（我找不到了）使用EclipseLink 2.5 MOXy进行JAXB服务。
I'm running a sample (which i can't find anymore) from Blaise Doughans blog on Glassfish 3 using EclipseLink 2.5 MOXy for JAXB service.
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class Company {
@XmlElementWrapper(name="employees")
@XmlElement(name = "employee", type=Employee.class)
private List<Employee> employees;
}
@XmlAccessorType(XmlAccessType.FIELD)
public class Employee {
private String id;
private String name;
}
我在类中添加了一些注释，以生成所需的json结构：
I added some annotations to the classes, to produce the desired json structure:
{
"employees": [
{
"id": "1",
"name": "Jane Doe",
"report": []
}
]
}
当我尝试解组这个JSON时，它遗憾地失败了，返回一个空员工列表的对象。
向JSON添加另一个元素列表或删除 @XmlElementWrapper 有效。
但我希望关键元素命名为 employees ，所以我必须使用包装注释？
When i try to unmarshal this JSON it sadly fails, returning an object with an empty employees list.
Adding another element to the JSON list OR removing the @XmlElementWrapper works.
But i want the key element to be named employees, so i have to use the wrapper annotation, or not?
编辑：
public class MyApplication extends Application {
@Override
public Set<Class<?>> getClasses() {
HashSet<Class<?>> set = new HashSet<Class<?>>(2);
set.add(MOXyJsonProvider.class);
set.add(Index.class);
return set;
}
@Override
public Set<Object> getSingletons() {
MOXyJsonProvider moxyJsonProvider = new MOXyJsonProvider();
moxyJsonProvider.setAttributePrefix("@");
moxyJsonProvider.setFormattedOutput(true);
moxyJsonProvider.setIncludeRoot(false);
moxyJsonProvider.setMarshalEmptyCollections(true);
moxyJsonProvider.setValueWrapper("$");
moxyJsonProvider.setWrapperAsArrayName(true);
HashSet<Object> set = new HashSet<Object>(1);
set.add(moxyJsonProvider);
return set;
}
}
