java - JAXB 和包含泛型的集合

Question

我们有下面的 JAXB/Java 代码。在我们更改 List<JQGridTO> rows 之前，这一切都很好至 List<? extends JQGridTO> rows .

当我们进行更改时，出现此错误:

Constructor threw exception; nested exception is com.sun. xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions Property rows appears in @XmlType.propOrder, but no such property exists. Maybe you meant records? this problem is related to the following location: at com.me.ui.service.JQGridJsonRoot

为什么会出现这个错误？您不能像我们一样使用泛型(即:指定 ? extends XXX )吗？

@XmlRootElement
@XmlType(name = "", propOrder = {
        "records",
        "page",
        "total",
        "rows"
})
public class JQGridJsonRoot {
    int total; //total pages for the query
    int page; //current page of the query
    int records; //total number of records for the query
    List<? extends JQGridTO> rows
    ...
