how to get ENUM variable with JPA

Question

I have a model with an ENUM field defined as:

@Enumerated(EnumType.STRING)
@Column(name = "CLASSIFICATION", length = 25)
private ClassificationEnum classification;

ClassificationEnum is defined as:

public enum ClassificationEnum {
  Type1,
  Type2,
  Type3;
}

On repository class, when I try to get the model with Type2 classification, I got the following error:

No enum constant [...].ClassificationEnum.2

The 2 is also the id of the class that contains my enum (maybe it's not related), but I don't know why JPA is trying to access my enum that way.

Answer 1

You should write the enum class like this:

public enum ClassificationEnum {
  Type1,
  Type2,
  Type3
}
