关于jsp 通过JDBC连接mysql乱码问题
我用的所有编码方式都是UTF-8
  我的连接数据库的字符串为jdbc:mysql://localhost/game?useUnicode=true&characterEncoding=UTF-8
mysql 数据库的编码方式为 character:UTF-8  collation:utf8_unicode_ci
浏览器设置的编码方式也是UTF-8
所有的jsp、servlet、和java文件的编码方式都是UTF-8
jsp 里的编码方式也是UTF-8
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
servlet中添加用户的函数为
	public void addUser(userBean user){
		PreparedStatement statement = null;
		Connection cnn = null;
		try{
			cnn = new ConnectionMysql().getConnection();
			statement = cnn.prepareStatement("insert user values(?,?,?,?,?,?,?,?,?)");//插入用户名称
			statement.setString(1, user.getUserName());
			statement.setString(2, user.getPassword());	
			statement.setString(3, user.getGroupName());
			statement.setString(4, user.getGroupRemark());	
			statement.setString(5, user.getCaptain1());
			statement.setString(6, user.getCaptain2());
			statement.setString(7, user.getCoach1());
			statement.setString(8, user.getCoach2());
			statement.setInt(9, user.getRange());
			statement.executeUpdate();			
			System.out.println(statement);			
		}// end try
		catch(Exception e){
			e.printStackTrace();
		}// end catch
		finally{
			close(null,statement,cnn);
		}
	}
System.out.println(statement)语句
只要文本框里面带了中文的全出现乱码
insert user values('aiaiia59272168421ff','aiaiia59272168421','?¨??°???°','è??vcxzxcv',' ??????','','','',1)
插入mysql 数据库时发现插进去的都是乱码
像用户注册模块注册失败时,本来应该在像“代表队”等文本框中返回注册前输入的值,可是也出现乱码
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
