主题：Re:mysql用普通客户端能登陆么？ (2004-08-09 23:49:42)
--------------------------------------------------------------------------------
我的环境是红旗linux桌面版4.0，
jakarta-tomcat-4.1.30，
mysql 4.1.0-alpha，
j2sdk1.4.2_04
mysql-connector-java-3.1.3-beta.tar.gz
我已经把mysql-connector-java-3.1.3-beta.tar.gz中的mysql-connector-java-3.1.3-beta-bin.jar拷贝到tomcat/common/lib下了。。。
并且在ｍｙｓｑｌ里“grant all on anywhere.* to anywhere@'%' identified by 'anywhere';”也就是允许任何人任何地点登录ｍｙｓｑｌ了，但还是出错，真是奇怪。。。
代码如下：
<%@page contentType="text/html;charset=gb2312"%>;
<%
//声名
java.sql.Connection sqlConn;
java.sql.Statement sqlStmt;
java.sql.ResultSet sqlRst;
//regiester jdbc driver
String DBUser="root";
String DBPassword="";
String DBServer="127.0.0.1"; // Can't use localhost , you must use IP or CNAME
String DBNAME="test"; // change to your db name
Class.forName("org.gjt.mm.mysql.Driver" .newInstance();
//connect to the database
sqlConn=java.sql.DriverManager.getConnection("jdbc:mysql://"+DBServer+":3306/"+DBNAME+"?useUnicode=true&characterEncoding=gb2312", DBUser,DBPassword);
//create the driver handle
sqlStmt=sqlConn.createStatement(java.sql.ResultSet.TYPE_SCROLL_INSENSITIVE,java.sql.ResultSet.CONCUR_READ_ONLY);
execute sql;
sqlRst=sqlStmt.executeQuery("select * from test";
%>;
<html>;
<head>;
<title>;</title>;
</head>;
<body>;
<table border="1" cellspace ="0" align="center">;
<tr>;<td>;DB CONNECT OK</td>;</tr>;
<tr>;
<th>;title</th>;
<th>;type </th>;
</tr>;
<% while(sqlRst.next()) {%>;
<tr>;
<td>;<%=sqlRst.getString(2)%>;</td>;
</tr>;
<%}%>;
</table>;
</body>;
</html>;
<%
sqlRst.close();
sqlStmt.close();
sqlConn.close();
%>; |
