【问题描述】：

所以你可以从标题中看到我的@JsonPropertyOrder 没有按我想要的方式排序......这是我的课程（见下面的代码），除了 zpp 属性外，所有的东西都很好，它介于“spravce”和“齐斯卡特莱”。我试图重命名它重新排序它并且它完全被忽略了。谢谢你的所有答案:)

（JacksonXML 版本 2.9.8）

@JacksonXmlRootElement(localName = "xmlroot")
@JsonPropertyOrder({"cnt-unik-id","kod-produktu","frekvence","datum-sjednani",
"pocatek","konec","spravce","ziskatele","objekty-unik-id","udaje","objekty-all","adresy","zpp"})
public class ContractDetail{

    @JacksonXmlProperty(localName = "zpp")
    private Integer zpplID;

    @JacksonXmlProperty(localName = "cnt-unik-id")
    private Integer id;

    @JacksonXmlProperty(localName = "kod-produktu")
    private Item product;

    @JacksonXmlProperty(localName = "spravce")
    private Item administrator;

    @JacksonXmlElementWrapper(localName = "ziskatele")
    @JacksonXmlProperty(localName = "xml-ziskatel")
    private List<Customer> customers;

    @JacksonXmlProperty(localName = "frekvence")
    private Item frequency;

    @JacksonXmlProperty(localName = "datum-sjednani")
    private Item createdAt;

    @JacksonXmlProperty(localName = "pocatek")
    private Item startDate;

    @JacksonXmlProperty(localName = "konec")
    private Item endDate;

    @JacksonXmlElementWrapper(localName = "objekty-unik-id")
    @JacksonXmlProperty(localName = "int")
    private List<Integer> vehicle;

    @JacksonXmlProperty(localName = "xml-hodnota")
    @JacksonXmlElementWrapper(localName = "udaje")
    private List<Item> values;

    @JacksonXmlProperty(localName = "xml-objekt")
    @JacksonXmlElementWrapper(localName = "objekty-all")
    private List<ObjectItem> objects;

    @JacksonXmlElementWrapper(localName = "adresy")
    @JacksonXmlProperty(localName = "xml-adresa")
    private List<AddressItem> address;

    //getters setters contructors stuff

}

【解决方案1】：

使用 Java 字段名称，而不是 XML 元素名称。

例如，使用您的ContractDetail 类的简化版本：

使用这个：

@JsonPropertyOrder({"id", "vehicle", "zpplID"})

生成这个：

<xmlroot>
    <cnt-unik-id>123</cnt-unik-id>
    <objekty-unik-id>
        <int>678</int>
        <int>789</int>
    </objekty-unik-id>
    <zpplID>456</zpplID>
</xmlroot>

然后使用这个：

@JsonPropertyOrder({"vehicle", "zpplID", "id"})

生成这个：

<xmlroot>
    <objekty-unik-id>
        <int>678</int>
        <int>789</int>
    </objekty-unik-id>
    <zpplID>456</zpplID>
    <cnt-unik-id>123</cnt-unik-id>
</xmlroot>

Soo @andrewjames 的回答有效，但如果有人仍然需要/想要使用 xml 元素名称，我想出的解决方案如下所示：

@JsonPropertyOrder({"cnt-unik-id","kod-produktu","frekvence","datum-sjednani",
"pocatek","konec","spravce","ziskatele","objekty-unik-id","int","udaje","xml-hodnota","objekty-all","xml-objekt","adresy","xml-adresa","zpp"})
