JAXB忽略内部元素

Question

我一直试图将自创建的xml配置文件解锁到具有JAXB默认实现的对象，我忽略了原因，但是一些内部元素和值被跳过，给出了空结果。

以下是xml文档：

<import-sources>
    <domain-objects>
        <domain-object class="xxx.xxx.core.business.mapping.Make">
            <sources>
                <source name="xxxxxx" class="xxx.xxx.core.web.common.model.xxxxxxx.output.MakeDTO">
                    <uri secured="true" value="xxxxxxxxxxxxxxxxxx"/>
                    <key name="api_key" mode="in_uri" value="xxxxxxxxxxxx"/>
                </source>
            </sources>
    </domain-object>
</domain-objects>

​

这是映射的类：

@XmlRootElement(name = "import-sources")
public class ImportSources {

    @XmlType
    public static class DomainObject {

        @XmlType
        public static class Source {

            @XmlType
            public static class URI {

                private String value;

                private boolean secured;
            }

            @XmlType
            public static class Key {

                @XmlEnum
                public enum Mode {
                    @XmlEnumValue("in_uri")
                    IN_URI,
                    @XmlEnumValue("in_header")
                    IN_HEADER
                }

                private String name;

                private String value;

                private Mode mode;
            }


            private String name;


            private URI uri;


            private Key key;

            @XmlElement(name = "class")
            private Class outputClass;
        }

        @XmlAttribute(name = "class")
        private Class<? extends Entity> subjectClass;

        @XmlElementWrapper
        @XmlElement(name = "source")
        private Source[] sources;
    }

    @XmlElementWrapper(name = "domain-objects")
    @XmlElement(name = "domain-object")
    private DomainObject[] domainObjects;
}

使用Unmarshaller.unmarshall()解析文档后，如果替换它的内部标记属性(如：

<source>
     <name>....</name>
     <class>...</class>
</source>

这是我想避免的，因为这是多余的。

Answer 1

我终于解决了我的问题，用@XmlAttribute在开始标记或单个标记中注释了我想要的所有字段。

Answer 2

我建议相应地将字段显式注释为@XmlElement或@XmlAttribute。然后，您的类将如下所示，并且字段将被填充：

@XmlRootElement(name = "import-sources")
public class ImportSources {

    @XmlType
    public static class DomainObject {

        @XmlType
        public static class Source {

            @XmlType
            public static class URI {


                @XmlAttribute //here
                private String value;

                @XmlAttribute //here
                private boolean secured;
            }

            @XmlType
            public static class Key {

                @XmlEnum
                public enum Mode {
                    @XmlEnumValue("in_uri")
                    IN_URI,
                    @XmlEnumValue("in_header")
                    IN_HEADER
                }

                @XmlAttribute //here
                private String name;

                @XmlAttribute //here
                private String value;

                @XmlAttribute //here
                private Mode mode;
            }


            @XmlAttribute //here
            private String name;

            @XmlElement //here
            private URI uri;

            @XmlElement //here
            private Key key;

            @XmlElement(name = "class")
            private Class outputClass;
        }

        @XmlAttribute(name = "class")
        private Class<? extends Entity> subjectClass;

        @XmlElementWrapper
        @XmlElement(name = "source")
        private Source[] sources;
    }
}
