Jackson field value with no quotation marks
Solution 1
As others have pointed out, double-quotes are not optional in JSON, but mandatory.
Having said that, you can use annotation JsonRawValue
to do what you want.
public class POJO {
public String name;
@JsonRawValue
public String click;
}
Solution 2
Well, technicaly you can do it. Although the result would not be a valid JSON, it is still possible with Jackson:
class Dto {
@JsonProperty("name")
String foo = "nameValue";
@JsonProperty("click")
JsEntry entry = new JsEntry("function (e){console.log(\"message\");}");
}
class JsEntry implements JsonSerializableWithType {
private String value;
JsEntry(String value) {
this.value = value;
}
@Override
public void serializeWithType(JsonGenerator jgen, SerializerProvider provider, TypeSerializer typeSer) throws IOException {
this.serialize(jgen, provider);
}
@Override
public void serialize(JsonGenerator jgen, SerializerProvider provider) throws IOException {
jgen.writeRawValue(value);
}
}
I'm fully agree, however, that this requirement causes a standard violation and should be revised.
Solution 3
That's not valid JSON, so you can't have it. JSON is a value transfer format, so you can't transfer functions.
If you really need to return functions in JSON, you can probably post-process the result in javascript.

Is there a Annotation or some other way to tell Jackson to Serialize a String variables's value without quotation marks. The serializer should only serialize the one field's value without quotation marks.
I am looking for a return of something similar to:
{"name": "nameValue", "click" : function (e){console.log("message");}}
instead of
{"name": "nameValue", "click" : "function (e){console.log("message");}"}
The above is how an external java script library requires the data, so if there is not a way i will have to manual alter the string after the Object Mapper has converted it to JSON.

ex0b1t over 10 yearsI know its not valid JSON. but that is the requirement.

Bozho over 10 yearssomeone devised a bad requirement :) can you post-process the result with javascript after it comes back from the server?
