hibernate 联合主键 注解 删除操作

实体对象：
@Entity
@Table(name = "T_DBCONNECT")
@IdClass(DBPK.class)
public class DataBaseConnect implements Serializable{


private String fassettype;

private String fdbtype;

private String fdbname;

private String fserver;
   
           /**set get method **/



}
主键对象：
public class DBPK implements Serializable{

         private String fassettype;

private String fdbtype;
    
         /**set get method **/

}



@Service
public class DataBaseConnectService {
   @Autowired
   private DataBaseConnectDao dbInfoDao;
   
   DataBaseConnect connect = null;
try{
    for(DBPK id : ids){
      connect = (DataBaseConnect)this.dbInfoDao.get(DataBaseConnect.class, id);
Map<String, String> propertyMap = new HashMap<String, String>();
this.dbInfoDao.delete(connect);
}
}catch(Exception e){
throw new YssException("删除失败:" + e.getMessage());
}
}



修改类似，增，查和原hibernate的方法没区别
