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
