Change value by annotation in SpringBoot Json

  • 772

I am using Springboot , I need to change the value of a variable when it is sent by JSON.

The problem is that in the database it only accepts 0 or 1 and the client expects true or false.

SpringBoot->

@JsonProperty("required")
@JsonFormat(shape = JsonFormat.Shape.BOOLEAN)
private int typerequired;

public int getTyperequired() {
    return typerequired;
}

public void setTyperequired(int typerequired) {
    this.typerequired = typerequired;
}

Angular2->

 console.log("LOS DATOS " , data);
 console.log(typeof(data[0].type));

I get 1 of type Number.

  1. What I can see in your code:

    • The attribute in Java is called typerequired.
    • You have annotated it so that in the JSON it appears as required.
    • In Javascript you look for it as type.

    Therefore the error should be resolved by changing data[n].typetodata[n].required

    I finally found the solution, to change the values ​​in Java and to be able to send a JSON changing the values.

    @JsonProperty("required")
@JsonFormat(shape = JsonFormat.Shape.BOOLEAN)
private int typerequired;

     @JsonGetter ("required")
 public boolean typeRequired () {

    boolean required = true;

    if(this.typerequired == 0) {
             required = false;
    }

     return required; 
    }
