Java JsonProperty-class And Method Code Example


I apologize for any confusion, there is no such class in Apache Commons IO library called JsonProperty. The class JsonProperty is from Jackson library, not from Apache Commons IO.

Here is an example of using the JsonProperty annotation from the Jackson library to specify the name of the key when serializing an object to JSON:

import com.fasterxml.jackson.annotation.JsonProperty;

public class MyClass {

    @JsonProperty("my_field")
    private String field;

    public MyClass(String field) {
        this.field = field;
    }

    public String getField() {
        return field;
    }
}

In this example, the field is annotated with @JsonProperty("my_field") which will be used as the key when serializing the MyClass object to JSON.

Make sure that you are using jackson as serializer.
