通过hibernatesession取表名、字段等

 1  protected String getTableNameByClass(Class<?> T){
 2         AbstractEntityPersister cm = (AbstractEntityPersister)
 3                 super.getHibernateSession().getSessionFactory().getClassMetadata(T);
 4         if(null!=cm){
 5             return cm.getTableName().toLowerCase();
 6         }
 7         return null;
 8     }
 9     protected Map<String,String> getColumnNameMap(Class<?> T){
10         AbstractEntityPersister cm = (AbstractEntityPersister)
11                 super.getHibernateSession().getSessionFactory().getClassMetadata(T);
12         Map<String,String> map = new HashMap();
13         if(null!=cm){
14             String[] propertyNames = cm.getPropertyNames();
15             for(int i = 0; i<propertyNames.length; i++){
16                 String[] columnNames = cm.getPropertyColumnNames(propertyNames[i]);
17                 if(null!=columnNames && columnNames.length>0){
18                     map.put(propertyNames[i],columnNames[0]);
19                 }
20             }
21         }
22         return map;
23     }
