It's simple. The sequence attribute has changed to sequence_name:

<id name="id" column="Id" type="java.lang.Long">
    <generator class="sequence" >
            <param name="sequence_name">SEQ_APP_Login_Log</param>   
    </generator>
</id>

class "sequence" is shortcut for "org.hibernate.id.SequenceGenerator" which is deprecated. use the following for hibernate5+:

<generator class="org.hibernate.id.enhanced.SequenceStyleGenerator">
    <param name="optimizer">none</param>
    <param name="increment_size">1</param>
    <param name="sequence_name">MY_SEQUENCE</param>
</generator>
