如何将带有xml字符串作为字段的对象序列化为xml并为此字段设置属性名称（杰克逊对象映射器）？

Question

I'm trying to serialize an object to xml with Object Mapper. An object's field is a xml string itself. I use @JsonRawValue so Jackson won't escape xml charactets, like < or /> . But, with @JsonRawValue Jackson ignores @JacksonXmlProperty annotation, and writes the string directly, omitting property name.

So this code:

public class Example {
   @JsonRawValue
   @JacksonXmlProperty(localName = "SOME_NAME")
   private String xml = "<xmlExample>123</xmlExample>";
}

produces:

<Example> <xmlExample>123</xmlExample> </Example>

When i want:

<Example>
    <SOME_NAME> <xmlExample>123</xmlExample> </SOME_NAME>
</Example>

So the proplem is that @JacksonXmlProperty doesn't work with @JsonRawValue. And i don't know how to get rid of @JsonRawValue, because without this annotation, Jackson escapes some xml characters.

UPDATE: Output generation code:

Example example = new Example();
String s = new XmlMapper().vriteValueAsString(example);

Try

 import com.fasterxml.jackson.databind.SerializationFeature;
 import com.fasterxml.jackson.dataformat.xml.XmlMapper;

 public static void main(String[] args) {

        try {
            Example example = new Example();
            XmlMapper xmlMapper = new XmlMapper();
            xmlMapper.enable(SerializationFeature.INDENT_OUTPUT);
            String xmlString = xmlMapper.writeValueAsString(example);
            System.out.println(xmlString);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Output:

<Example><SOME_NAME><xmlExample>123</xmlExample></SOME_NAME></Example>
