使用 XmlMapper 时发生 UnrecognizedPropertyException

Question

XML 字符串

一个 profilesBatch 包含 1 个 profilesList
profilesList 包含一个或多个配置文件
配置文件包含 1 个 useRestrictions

<profilesBatch version="1.0" id="745" date="2012-12-13" transportKeyLabel="str1234">
  <profilesList>
    <profile iccid="str1234" profileType="str1234">
      <useRestrictions>
        <maximumDownloadAttempts>745</maximumDownloadAttempts>
        <maximumConfirmationAttempts>745</maximumConfirmationAttempts>
        <maximumNumberEIDs>745</maximumNumberEIDs>
        <maximumDownloadsPerEID>745</maximumDownloadsPerEID>
        <allowDownloadForDownloaded>true</allowDownloadForDownloaded>
        <allowDownloadForInstalled>true</allowDownloadForInstalled>
        <allowDownloadForError>true</allowDownloadForError>
      </useRestrictions>
    </profile>
  </profilesList>
</profilesBatch>

Class 配置文件批处理

@Getter
@Setter
@XmlRootElement(name = "ProfilesBatch")
public class ProfilesBatch
{
    @JacksonXmlProperty(isAttribute = true)
    private String date;

    @JacksonXmlElementWrapper(localName="profilesList")
    @JacksonXmlProperty(localName="profilesList")
    private ProfilesList profilesList;

    @JacksonXmlProperty(isAttribute = true)
    private String transportKeyLabel;

    @JacksonXmlProperty(isAttribute = true)
    private Header header;

    @JacksonXmlProperty(isAttribute = true)
    private String id;

    @JacksonXmlProperty(isAttribute = true)
    private String version;

}

Class 配置文件列表

@Getter
@Setter
@XmlRootElement(name = "ProfilesList")
public class ProfilesList
{
    @JacksonXmlElementWrapper(localName="profile")
    @JacksonXmlProperty(localName="profile")
    private List<Profile> profile;
}

Class个人资料

@Getter
@Setter
@XmlRootElement(name = "Profile")
public class Profile
{
    @JacksonXmlProperty(isAttribute = true)
    private String iccid;

    @JacksonXmlProperty(isAttribute = true)
    private String profileType;

    @JacksonXmlElementWrapper(localName="useRestrictions")
    private UseRestrictions useRestrictions;

}

Class 使用限制

@Getter
@Setter
@XmlRootElement(name = "useRestrictions")
public class UseRestrictions {

    @JacksonXmlProperty(localName = "maximumDownloadAttempts")
    private int maximumDownloadAttempts;

    @JacksonXmlProperty(localName = "maximumNumberEIDs")
    private int maximumNumberEIDs;

    @JacksonXmlProperty(localName = "maximumConfirmationAttempts")
    private int maximumConfirmationAttempts;

    @JacksonXmlProperty(localName = "maximumDownloadsPerEID")
    private int maximumDownloadsPerEID;

    @JacksonXmlProperty(localName = "allowDownloadForInstalled")
    private boolean allowDownloadForInstalled;

    @JacksonXmlProperty(localName = "allowDownloadForDownloaded")
    private boolean allowDownloadForDownloaded;

    @JacksonXmlProperty(localName = "allowDownloadForError")
    private boolean allowDownloadForError;

}

我正在使用 spring-boot with jackson-dataformat-xml。做的时候

XmlMapper xmlMapper = new XmlMapper();
ProfilesBatch profilesBatch = xmlMapper.readValue(data, ProfilesBatch.class);

其中数据是 xml 字符串

正在

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException:Unrecognized field "maximumDownloadAttempts" (class sm.movasim.sftp.service.espgmodel.Profile), not marked as ignorable

类和注解有什么问题吗？请注意，所有类都有 setter 和 getter

Answer 1

修改你的ProfilesListclass

    @Getter
    @Setter
    @XmlRootElement(name = "ProfilesList")
    public static class ProfilesList {
        @JacksonXmlElementWrapper(localName = "profile", useWrapping = false)
        @JacksonXmlProperty(localName = "profile")
        private List<Profile> profile;
    }

原因：默认 @JacksonXmlElementWrapper 需要包装器标签 => 您的 <profile> 列表需要包装在另一个 <profile></profile> 级别，请设置 useWrapping = false 来避免它。

Answer 2

您实际上并不需要 ProfileList class。

直接在 ProfileBatch class 中添加这些注释的列表：

@XmlRootElement(name = "ProfilesBatch")
public class ProfilesBatch
{
    @JacksonXmlElementWrapper(localName="profilesList")
    @JacksonXmlProperty(localName="profile")
    private List<Profile> profilesList;

另外，在旁注中，在配置文件中 class UseRestrictions 可以被注释

@JacksonXmlProperty(localName="useRestrictions")
private UseRestrictions useRestrictions;

您不需要对象的包装器注释。
