如何避免JAXB提取元素的命名空间并将其放在根元素的位置

Question

请帮我解决以下问题：

我正在使用Jersey，我有一个XML，这个XML带有一个名为＆＃34;定义＆＃34;的类。注释好的XML注释，XML看起来像：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

问题是，每次我得到几个这样的结果，所以我把它放在一个新的类中，我为每个＆＃34;定义＆＃34;，我的新类看起来像这样（它是由xsd by xjc生成的：

  @XmlAccessorType(XmlAccessType.FIELD)
    @XmlType(name = "", propOrder = {
        "specification"
    })
    @XmlRootElement(name = "MuTopologies")
    public class MuTopologies {

        protected List<MuTopologies.Specification> specification;


        public List<MuTopologies.Specification> getSpecification() {
            if (specification == null) {
                specification = new ArrayList<MuTopologies.Specification>();
            }
            return this.specification;
        }



        @XmlAccessorType(XmlAccessType.FIELD)
        @XmlType(name = "", propOrder = {
            "definitions"
        })
        public static class Specification {

            @XmlElement(name = "Definitions", required = true,namespace="http://docs.oasis-open.org/tosca/ns/2011/12")
            protected org.eclipse.toscaModel.Definitions definitions;
            @XmlAttribute(name = "id", required = true)
            protected int id;


            public org.eclipse.toscaModel.Definitions getDefinitions() {
                return definitions;
            }


            public void setDefinitions(org.eclipse.toscaModel.Definitions value) {
                this.definitions = value;
            }


            public int getId() {
                return id;
            }


            public void setId(int value) {
                this.id = value;
            }



            @XmlAccessorType(XmlAccessType.FIELD)
            @XmlType(name = "")
            public static class Definitions
                extends TDefinitions
            {


            }

        }

    }

然后我使用JAXB编组它，我几乎可以得到完美的结果，看起来像这样：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<MuTopologies xmlns:tosca="http://docs.oasis-open.org/tosca/ns/2011/12">
    <specification id="1">
        <tosca:Definitions targetNamespace="http://www.example.org/" id="winery-defs-for_ex1-MediaWiki">
           ........
        </tosca:Definitions>
    </specification>
    <specification id="2">
        <tosca:Definitions targetNamespace="http://www.example.org/" id="winery-defs-for_ex1-MediaWiki">
           ........
        </tosca:Definitions>
    </specification>
</MuTopologies>

唯一的问题是我的命名空间在＆＃34;定义＆＃34;移动到我的新XML的根元素（xmlns：tosca =＆＃34; http：//docs.oasis-open.org/tosca/ns/2011/12"），我不想要这个，我想要这样：

   <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <MuTopologies >
        <specification id="1">
            <tosca:Definitions xmlns:tosca="http://docs.oasis-open.org/tosca/ns/2011/12" targetNamespace="http://www.example.org/" id="winery-defs-for_ex1-MediaWiki">
               ........
            </tosca:Definitions>
        </specification>
        <specification id="2">
            <tosca:Definitions xmlns:tosca="http://docs.oasis-open.org/tosca/ns/2011/12" targetNamespace="http://www.example.org/" id="winery-defs-for_ex1-MediaWiki">
               ........
            </tosca:Definitions>
        </specification>
    </MuTopologies>

有没有一种方法可以避免JAXB提取Element的命名空间？如果没有，有没有办法包装我的每一个＆＃34;定义＆＃34;新的xml中的xml ??

非常感谢。我试着在整个周末解决它，这让我发疯。感谢。
