jsp從web.xml得到數據庫的配置信息

我們先需要了解的就是我們的配置文件參數意義 param-name配置web參數名param-value:配置web參數名
下面就是我們在web.xml裏面添加的參數信息
<context-param>
<param-name>dirver</param-name>
<param-value>com.sql.jdbc.driver</param-value>
</context-param>
<context-param>
<param-name>url</param-name>
<param-value>jdbc:mysql://localhost:3036/javaee</param-value>
</context-param>
<context-param>
<param-name>user</param-name>
<param-value>root</param-value>
</context-param>
<context-param>
<param-name>pass</param-name>
<param-value>123456</param-value>
</context-param>
那下面就是我們jsp文件的調用的方法了。
<%
String dirver = application.getIntParameter("dirver");
String url = application.getIntParameter("url");
String user = application.getIntParameter("user");
String pass = application.getIntParameter("pass");
