反序列化XML消息时遇到此错误：

无法识别的字段“ schemaLocation”（com.example.RefreshTokenType类），未标记为可忽略（4个已知属性：“ authorized_party”，“ audience”，“ meta”，“ client_id”]）。

ID Time_Stamp                     A           B                 C

背景是我要从 org.eclipse.persistence.moxy 切换到 FasterXML / Jackson 以便用Jersey封送JSON和XML。一切正常，直到得到包含 schemaLocation 的XML消息。

这是我的反序列化设置：

<p:RefreshToken authorized_party="" client_id="15d8b31f4823aeaf21d3ba6ee87a4557"
    xmlns:p="http://example.com/xsd/oauth/v2/oauth-spec.xsd"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://example.com/xsd/oauth/v2/oauth-spec.xsd oauth-v2-spec.xsd ">
    <p:meta id="meta111" locale="*" name="x" value="x" />
</p:RefreshToken>

这是我的http://example.com/xsd/oauth/v2/oauth-spec.xsd的摘录：

public static void enableDeserializationSetting(ObjectMapper reader) {
  Set<Class<?>> jaxbClasses = collectJaxbAnnotatedClasses();
  reader.registerModule(new JaxbAnnotationModule());
  reader.enable(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY);
  reader.registerSubtypes(jaxbClasses);
}

有人可以照亮吗？

Answer 1

您可以在ObjectMapper中禁用FAIL_ON_UNKNOWN_PROPERTIES功能：

mapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);

或者，您可以使用@JsonIgnoreProperties将ignoreUnknown设置为true：

@JsonIgnoreProperties(ignoreUnknown = true)
public class RefreshTokenType {
    ...
}
