查看表的编码 >show create table person; 5、在jsp页面要如下配置 <%@ page language="java" import="java.util.*" pageEncoding="gb2312"%> 6、在连接mysql类里要如下设置 String driverName = "com.mysql.jdbc.Driver";//"org.gjt.mm.mysql.Driver"两个驱动都可以用
String dbHost = host;//数据库的一些信息
String dbPort = port;
String dbName = dbaName;
String enCoding = "?useUnicode=true&characterEncoding=gb2312"; //解决MySql中文问题,要连续写不能空格
String userName = usName;
String Psw = psw;
String url = "jdbc:mysql://" + dbHost + ":" + dbPort + "//m.sbmmt.com/m/" + dbName+enCoding;
try
{
Class.forName(driverName).newInstance();
dbconn = DriverManager.getConnection(url, userName, Psw);
//getConnection(url, userName, Psw)从给的driver中选择合适的去连接数据库
//return a connection to the URL
}catch(Exception e){
print("url = " + url); //发生错误时，将连接数据库信息打印出来
print("userName = " + userName);
print("Psw = " + Psw);
print("Exception: " + e.getMessage());//得到出错信息
}
if (dbconn != null)//dbconn != null 表示连接数据库成功，由异常保证！？
return true;
else
return false;bitsCN.com
