使用
initParam您可以获得上下文参数。
创建
context-params在
web.xml数据库连接属性：
<context-param> <param-name>driverClass</param-name> <param-value>com.mysql.jdbc.Driver</param-value></context-param><context-param> <param-name>connectionURL</param-name> <param-value>jdbc:mysql://localhost/dbname</param-value></context-param><context-param> <param-name>username</param-name> <param-value>foo</param-value></context-param><context-param> <param-name>password</param-name> <param-value>bar</param-value></context-param>
在JSP中使用
<sql:setDataSource var="dataSource" driver="${initParam['driverClass']}" url="${initParam['connectionURL']}" user="${initParam['username']}" password="${initParam['password']}" />
