I have an element "SubElement2" that has value and attribute.

Working :

My Annotation are

 @XmlValue 
 @JsonProperty(value="content")
 private String value;

Request in XML : <SubElement2 parameterName = "tested">ELEMENT_2_TAG_VAL</SubElement2>

TO JSON :

 "SubElement2" : 
 "content" : "ELEMENT_2_TAG_VAL",
 "parameterName" : "tested"
 

Here I want to change the property name content to myOwnContent

Not Working:

Modified annotations :

 @XmlValue 
 @JsonProperty(value="myOwnContent") // Modified
 private String value;

Request in XML : <SubElement2 parameterName = "tested">ELEMENT_2_TAG_VAL</SubElement2>

For the above annotation change, I'm facing below exception:

Exception in thread "main" com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "content" (class SubElement2), not marked as ignorable (2 known properties: "parameterName", "myOwnContent"])
 at [Source: (String)""SubElement2":"parameterName":"tested","content":"ELEMENT_2_TAG_VAL""; line: 1, column: 53] (through reference chain: Element1["SubElement2"]->SubElement2["content"])
 at com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException.from(UnrecognizedPropertyException.java:60)

Below is my code :
ObjectFactory.java

@XmlRegistry
public class ObjectFactory 

 public SubElement2 createSubElement2() 
 return new SubElement2();
 

MainProgram.java

public class MainProgram 

 public static void main(String[] args) throws ClassNotFoundException, IOException 
 String request = "<SubElement2 parameterName = "tested">ELEMENT_2_TAG_VAL</SubElement2>";
 System.out.println("Request in XML : "+request);
 JSONObject jObject = XML.toJSONObject(request);

 ObjectMapper mapper = createCombinedObjectMapper();
 Object json = mapper.readValue(jObject.toString(), Class.forName("Element1"));
 String output = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(json);
 System.out.println(output);
 

 private static ObjectMapper createCombinedObjectMapper() 
 return new ObjectMapper().configure(SerializationFeature.WRAP_ROOT_VALUE, false)
 .configure(DeserializationFeature.UNWRAP_ROOT_VALUE, false)
 .configure(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true)
 .setAnnotationIntrospector(createJaxbJacksonAnnotationIntrospector());
 

 private static AnnotationIntrospector createJaxbJacksonAnnotationIntrospector() 
 final AnnotationIntrospector jaxbIntrospector = new JaxbAnnotationIntrospector(TypeFactory.defaultInstance());
 final AnnotationIntrospector jacksonIntrospector = new JacksonAnnotationIntrospector();
 return AnnotationIntrospector.pair(jacksonIntrospector, jaxbIntrospector);
 

SubElement2.java

@XmlRootElement(name = "SubElement2")
public class SubElement2 
 @XmlValue 
 @JsonProperty(value="myOwnContent")
 private String value;
 @JsonProperty(value="parameterName",required=true)
 @XmlAttribute(required = true)
 protected String parameterName;
 public String getValue() 
 return value;
 
 public void setValue(String value) 
 this.value = value;
 
 public String getParameterName() 
 return parameterName;
 
 public void setParameterName(String parameterName) 
 this.parameterName = parameterName;
 

Element1.java

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "element1", propOrder = 
 "element1"
)
@XmlRootElement(name = "Element1")
public class Element1 

 @XmlElement(name="SubElement2")
 protected SubElement2 subElement2;

 public SubElement2 getSubElement2() 
 return subElement2;
 

 public void setSubElement2(SubElement2 subElement2) 
 this.subElement2 = subElement2;
 

I'm using Jackson version : 2.9.7

Help me to solve this exception ,thanks in advance

What I want to do :

I want to have jsonproperty as myOwnContent because content is already used by another attribute in XML in my existing implementation. (Existing implementation doesn't have JSON suuport , we are adding JSON support)
