2. 確認MySql驅動是否存放在tomcat下的common\lib文件夾中
3. 測試數據源的配置是否成功
(1) 在web.xml中添加如下代碼
<resource-ref>
<description>DataSource</description>
<res-ref-name>jdbc/mysql</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
(2) 測試數據源
<html>
<head>
<title>test jndi</title>
</head>
<body>
<%
Context initCtx = new InitialContext();
Context ctx = (Context) initCtx.lookup("java:comp/env"); DataSource ds = (DataSource) ctx.lookup("jdbc/mysql");
Connection conn = ds.getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select * from user_info");
while (rs.next()) {
%>
<%=rs.getInt(1)%>
<%
}
rs.close();
stmt.close();
conn.close();
%>
</body>
