JsonPropertyOrder无法正确订购

如何解决JsonPropertyOrder无法正确订购

因此，从标题中可以看到，我的@JsonPropertyOrder并未按我的意愿进行排序...这是我的课程（请参见下面的代码），除zpp属性外，其他所有东西都按顺序排列良好，它介于“ spravce”和“ ziskatele”。我试图重命名它，将其重新排序，并完全忽略了。谢谢您的所有回答：）

（JacksonXML 2.9.8版）

@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

}

解决方法

使用Java字段名称代替XML元素名称。

例如，使用您的ContractDetail类的简化版本：

使用此：

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

生成此：

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

并使用它：

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

生成此：

<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的答案有效，但是如果有人仍然需要/想要使用xml元素名称，那么我想出的解决方案如下：

@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"})
