How to fix org.codehaus.Hymanson.map.exc.UnrecognizedPropertyException
提问by blue-sky
Here is the snippet of code that is causing the exception :
这是导致异常的代码片段：
org.springframework.web.client.RestTemplate rt
.getForObject(uri, type, vars);
The exception is :
例外是：
nested exception is org.codehaus.Hymanson.map.exc.UnrecognizedPropertyException: Unrecognized field "d" (Class com.xsd.myObj), not marked as ignorable
嵌套异常是 org.codehaus.Hymanson.map.exc.UnrecognizedPropertyException: Unrecognized field "d" (Class com.xsd.myObj)，未标记为可忽略
Does this mean there is a field called "d" in the xml document being read that is expected to be in the java/xsd file ? What steps can I take to fix this error ?
这是否意味着正在读取的 xml 文档中有一个名为“d”的字段，该字段应该在 java/xsd 文件中？我可以采取哪些步骤来修复此错误？

This means that there are getand setmethods of an object in your class and Hymanson is unable to figureout the serialization and deserialization process.
这意味着您的类中有对象的方法get和set方法，而 Hymanson 无法弄清楚序列化和反序列化过程。
Use @JsonIgnoreif you don't want the property to be serialized.
使用@JsonIgnore，如果你不希望属性被序列化。
If you would like to have this data serialized and deserialized, it could be a problem with polymorphic references. Check Hymanson's Annotation guidefor appropriate usage. You may be interested in @JsonTypeInfoin such cases.
如果您希望对这些数据进行序列化和反序列化，则多态引用可能会出现问题。检查Hymanson 的 Annotation 指南以了解适当的用法。您可能对@JsonTypeInfo此类情况感兴趣。
