My Hibernate version is 4.3
My Class Career has a composite primary key CareerId, and when use hibernate tool reveng.xml to generate, class Career and class CareerId is generated, but only Career.hbm.xml is generated, CareerId.hbm.xml is not gnereated.
And in database, only Career table is existed, no CareerId table is existed.
From the stacktrace,
Caused by: org.hibernate.MappingException: component class not found: CareerId
is this mean the error is due to no CarrerId.hbm.xml is generated?
My Hibernate.config.xml is as follow:
<?xml version="1.0" encoding="UTF-8"?>
