In DB, one table has a column with datatype is SET
Link: http://stackoverflow.com/q/23949030

I config like that:

@Column(name = "workingDays", nullable = false, unique = false)
@Type(type="org.hibernate.type.settype")
private Set<String> workingDays; 

But,

Caused by: java.lang.ClassNotFoundException: org.hibernate.type.settype

Change to org.hibernate.type.SetType, but
Caused by: org.hibernate.MappingException: Could not instantiate Type: org.hibernate.type.SetType
