Hibernate实现分表

public class QueryResInterceptor extends EmptyInterceptor{

private String oldName;
private String newName;
public QueryResInterceptor(String oldName,String newName){
this.oldName = oldName;
this.newName = newName;
}
//重写该方法，hibernate是封装了jdbc的，但他底层还是通过sql来操作的。
public String onPrepareStatement(String sql) {
sql = sql.replace(oldName,newName);
return sql;
}
}

public void saveUser(String oldName,String newName,User user){
QueryResInterceptor interceptor = newQueryResInterceptor(oldName,newName);
Session session = super.getHibernateTemplate().getSessionFactory().openSession(interceptor);
try {
session.save(user);
} catch (HibernateException e) {
e.printStackTrace();
}finally{
session.close();
}
}
