JDBC链接数据库 使用web.xml 读取数据库配置

使用以下方法会提示已过时：

string cnnStr = System.Configuration.ConfigurationSettings.AppSettings["cnn"];

应改为使用

string server = System.Configuration.ConfigurationManager.AppSettings["server"];

String db ="server=" + server + ";uid=" + uid + ";pwd=" + pwd + ";database=" + database;SqlConnection dsConn = new SqlConnection(db);

在web.xml里添加：

<appSettings>      <add key = "server" value = "10.0.1.15"/>      <add key = "uid" value = "kq"/>      <add key = "pwd" value = "xxx"/>      <add key = "database" value = "ATT2000SQL"/>  </appSettings>
