Spring JPA bi-directional cannot evaluate toString

Question

I have resolved JSON recursive loop with @JsonIdentityInfothrough to Baeldung\'s blog1 (Thanks)

But now, another error occurs :

Method threw         


        

Answer 1

in your Registration.toString() you are calling a Payment.toString() and on your Payment.toString() you are calling Registration.toString()

You have created a loop in toString

  @Override
  public String toString() {
     return MoreObjects.toStringHelper(this)
        .add("payment", payment) //<----------- REMOVE THIS
        .toString();
  }

or

   @Override
   public String toString() {
   return MoreObjects.toStringHelper(this)
        .add("registration", registration) //<----------- REMOVE THIS
        .toString();
   }

Or better... remove both
