通过PreparedStatement批量执行sql语句【sql语句相同，值不同】

public void addCustomerByCommit(Connection conn , List<Customer> customerList) 
{ 
   String sql = "inseret into customer(id , name , remark)values(?,?,?)"; 
   try 
        { 
            PreparedStatement ps = conn.prepareStatement(sql); 
            for(Customer customer :customerList){
                 int index = 1; 
                 ps.setInt(index++ , customer.getId()) 
                 ps.setString(index++, customer.getName()); 
                 ps.setString(index++, customer.getRemark()); 
                 ps.addBatch();
            }
            ps.executeBatch(); 
        } 
        catch (SQLException e) 
        { 
            //这里呢你可以做点自己想做的事情 
            e.printStackTrace(); 
        } 
}
