A Solution for Equals and HashCode Method of Hibernate Domain Ojbect

Issue:

Solution:
every domain object extends the following object.

public abstract class BaseObject {
    
    private String uuid = UUID.randomUUID().toString();

    public String getUuid() {
        return uuid;
    }

    public void setUuid(String uuid) {
        this.uuid = uuid;
    }

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((uuid == null) ? 0 : uuid.hashCode());
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        final BaseObject other = (BaseObject) obj;
        if (uuid == null) {
            if (other.uuid != null)
                return false;
        } else if (!uuid.equals(other.uuid))
            return false;
        return true;
    }
}
