is it possible to ignore some field when mapping in annotation,Entity class [duplicate]

Question

I am using Hibernate to map with MySQL

I have an entity class in which I have the methods mapped with columns in MySQL

The question is, if its possible that I do not map some of the method in that class with any column in SQL, as if i try not to map one of my method in entity class, it gives exception.

Here is the code snippet

@Column(name="skills")
public String getSkills() {
    return skills;
}

public int getRowCount() {
    return rowCount;
}

In this above code I have assigned getSkills with Column skills in SQL, but I do not want to assign getRowCount() with any column in MySQL.

How could i achieve that (as in this above situation its giving exception, rowCount is unknown)?

Answer 1

Use the @Transient annotation:

This annotation specifies that the property or field is not persistent. It is used to annotate a property or field of an entity class, mapped superclass, or embeddable class.

i.e.

@Column(name="skills")
public String getSkills() {
    return skills;
}

@Transient
public int getRowCount() {
    return rowCount;
}
