I am using JPA 2.1. I want to genrate mysql enum type column like: gender enum('male','female')
. My Enum class is
public enum Gender {
MALE,
FEMALE
}
In JPA entity class
@Enumerated
private Gender gender;//generate int type column
And
@Enumerated(EnumType.STRING)
private Gender gender; //generate varchar type column.
Is there any way to generate enum type column in MySql?
Use following code:
public enum Gender {
MALE, FEMALE;
}
@Enumerated(EnumType.STRING)
@Column(columnDefinition = "ENUM('User', 'Moderator', 'Admin')")
public Role role;
}
If you would like to use string enumeration value in database, the column type must be varchar
base on database sever. Actually, I am not clear I want to genrate mysql enum type column
. But, if u would like to display the output MALE
to male
, reference as below :
public enum Gender {
FEMALE("female"), MALE("male");
private String label;
private Gender(String label) {
this.label = label;
}
public String getLabel() {
return label;
}
}
test calss
public static void main(String args[]) {
System.out.println(Gender.MALE)
}
Output : male
