JAXB忽略内部元素

Question

我一直在尝试将自行创建的xml配置文件解编到具有JAXB默认实现的对象中，我忽略了原因，但是跳过了一些内部元素和值，使结果为空。

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;
}

用Unmarshaller.unmarshall（）解析文档后，所有Source的字段都为空，如果我替换其内部标记属性，则可以得到其标量字段：

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

由于冗余，我要避免这种情况。

我终于通过用'@XmlAttribute'注释打开标签或单个标签内的所有字段来解决我的问题。

Answer 2

我建议相应地将字段显式注释为@XmlElement或@XmlAttribute 。 然后，您的班级将类似于以下内容，并填充字段：

@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;
    }
}
