注意最上面的两个column name,两个一样:Repeated column in mapping for entity
执行insert,update的时候:
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
%%%% Error Creating SessionFactory %%%%
org.hibernate.MappingException: Repeated column in mapping for entity: com.wsw.model.Plasmids co
