Question

我一直试图将自创的xml配置文件解组为具有JAXB默认实现的对象，我忽略了原因，但是跳过了一些内部元素和值，给出了null结果。

这是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，所有Source的字段都为null，如果我替换它的内部标记属性，我可以得到它的标量字段：

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

由于冗余，我想避免使用。

Answer 1

我最终通过使用'@XmlAttribute'在开始标记或单个标记中注释我想要的所有字段来解决我的问题。

Answer 2

我建议相应地明确地将字段注释为@XmlAttribute或@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; } }。您的课程将如下所示，字段将填充：
