如何将xml元素解析为基元类型？

Question

<order>
    <id_address_delivery>4</id_address_delivery>
</order>

@JacksonXmlRootElement(localName = "order")
public static class Order
{
    @JacksonXmlProperty(localName = "id_address_delivery")
    public String id_address_delivery;
}

XmlMapper XmlMapper = new XmlMapper()
XmlMapper.readValue(xml, Order.class);

我得到的错误是：无法将java.lang.String实例反序列化出START_OBJECT令牌

如何将xml元素反序列化更正为基元类型？

Answer 1

编辑：你能确认变量“cls”是order.class吗？如果cls是string.class，我会得到您报告的错误，但这不是正确的方法，因为您解析的是 元素，而不是 元素。

您是否有可能导致问题的定制配置？也许是不可靠的空白-尝试完全删除空白？

public class Jackson {

    @JacksonXmlRootElement(localName = "order")
    private static class Order
    {
        @JacksonXmlProperty(localName = "id_address_delivery")
        public String id_address_delivery;
    }

    public static void main(String[] args) throws IOException {

        XmlMapper mapper = new XmlMapper();
        Order order = mapper.readValue("<order>\n\t<id_address_delivery>4</id_address_delivery></order>", Order.class);

        System.out.println(ToStringBuilder.reflectionToString(order, ToStringStyle.JSON_STYLE));
    }
