jsp中如何执行insert语句

jsp执行insert语句吗？ 问题太含糊了，如果是操作数据库的话，最好在action里处理，然后再DAO层进行数据库操作，给你个方法 public List query(){ List message=new ArrayList(); DBManager db = new DBManager(); String sql = "select * from message"; PreparedStatement pstmt=null; ResultSet rs=null; Connection conn=db.getConn(); try { pstmt = conn.prepareStatement(sql); rs = pstmt.executeQuery(); while(rs.next()){ Message m=new Message(rs.getInt("id"),rs.getString("face"),rs.getString("title"),rs.getString("content"),rs.getDate("createTime"), rs.getString("ip"),rs.getString("author")); message.add(m); } rs.close(); pstmt.close(); conn.close(); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } return message; } 如果你用Hibernate的话，会更简单
