Jackson: Ignore Json configuration value

Question

I have the following json file:

{
  \"segments\": {        
            \"externalId\": 123, 
            \"name\": \"Tomas Zulberti\", 
            \"shoul         


        

Answer 1

Also we can use mapper.enable(DeserializationFeature.FAIL_ON_IGNORED_PROPERTIES); instead @JsonIgnoreProperties(ignoreUnknown=true)

but for particular property we can use

@JsonIgnoreProperties({"externalId"})
public class Segment {

    private String id;
    private String name;
    private boolean shouldInform;

    // getter and setters here...
}

Answer 2

You can use annotation @JsonIgnoreProperties; if it's just one value you want to skip, something like:

@JsonIgnoreProperties({"externalId"})

or to ignore anything that can't be used:

@JsonIgnoreProperties(ignoreUnknown=true)

There are other ways to do it too, for rest check out FasterXML Jackson wiki.
