Hibernate中session.connection()的替代方法
     Hibernate3.3.2版本中getSession().connection()已被弃用,替代方法SessionFactoryUtils.getDataSource(getSessionFactory()).getConnection()

来自类org.springframework.orm.hibernate3.SessionFactoryUtils

例子:

  

java.sql.Connection c = null;
         java.sql.PreparedStatement ps = null;
         java.sql.ResultSet rs = null;public List   method(String sql) {
         List ret = new ArrayList();
         try {
         c = SessionFactoryUtils.getDataSource(getSessionFactory()).getConnection();
             ps = c.prepareStatement(sql);
             rs = ps.executeQuery();
             while(rs.next()) {
                  .....
                 }
                 ret.add(ro);
             }
         } catch (Exception e) {
              e.printStackTrace();       } finally {
            close();
         }
         return ret;
     }

Hibernate API中让使用doWork(Work,work),描述如下:

() 
 Deprecated. (scheduled for removal in 4.x). Replacement depends on need; for doing direct JDBC stuff use ; for opening a 'temporary Session' use (TBD).         Work接口的execute()方法用于执行直接通过JDBC API来访问数据库的操作:
 public interface Work {
 //直接通过JDBC API来访问数据库的操作
 public void execute(Connection connection) throws SQLException;
 }


Session的doWork(Work work)方法用于执行Work对象指定的操作,即调用Work对象的execute()方法。Session会把当前使用的数据库连接传给execute()方法。

过程如下:

Transaction tx=session.beginTransaction();
 //定义一个匿名类,实现了Work接口
 Work work=new Work(){
 public void execute(Connection connection)throws SQLException{
 //通过JDBC API执行用于批量更新的SQL语句
 PreparedStatement stmt=connection
 .prepareStatement("update CUSTOMERS set AGE=AGE+1 "
 +"where AGE>0 ");
 stmt.executeUpdate();
 }
 };
