给没有搞定tamcat+msyql 乱码问题的哥们儿一个方法

在mysql 创建test数据库字符集：UTF-8

Mysql代码

Create DATABASE test default charset utf8;
CREATE TABLE `people` (
`id` int(10) NOT NULL auto_increment,
`name` varchar(100) default NULL,
`msg` text,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

Create DATABASE test default charset utf8;CREATE TABLE `people` (  `id` int(10) NOT NULL auto_increment,  `name` varchar(100) default NULL,  `msg` text,  PRIMARY KEY  (`id`)) ENGINE=MyISAM DEFAULT CHARSET=utf8;

把jsp文件都保存问UTF-8编码

jsp页面控制脚本

Java代码

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<%@ page contentType="text/html; charset=UTF-8" language="java" import="java.sql.*" errorPage="" %>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><%@ page contentType="text/html; charset=UTF-8" language="java" import="java.sql.*" errorPage="" %><meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

数据库连接脚本

Java代码

String driverName="org.gjt.mm.mysql.Driver";
String dbName="test";
String tableName="people";
String dbuser="alang";
String dbpass="lingting";
String url="jdbc:mysql://localhost:3306/"+dbName+"?user="+dbuser+"&password="+dbpass+"&useUnicode=true&characterEncoding=UTF-8";
Class.forName(driverName).newInstance();
Connection conn=DriverManager.getConnection(url);
Statement stmt = conn.createStatement();
String sql="SELECT * FROM "+tableName;
ResultSet rs = stmt.executeQuery(sql);

String driverName="org.gjt.mm.mysql.Driver";String dbName="test";String tableName="people";String dbuser="alang";String dbpass="lingting";String url="jdbc:mysql://localhost:3306/"+dbName+"?user="+dbuser+"&password="+dbpass+"&useUnicode=true&characterEncoding=UTF-8";Class.forName(driverName).newInstance();Connection conn=DriverManager.getConnection(url);Statement stmt = conn.createStatement();String sql="SELECT * FROM "+tableName;ResultSet rs = stmt.executeQuery(sql);

显示脚本

Java代码

while(rs.next()) {
String str_name=new String(rs.getString("name").getBytes("ISO-8859-1"),"UTF-8");
}
<%= str_anme%>

while(rs.next()) {   String str_name=new String(rs.getString("name").getBytes("ISO-8859-1"),"UTF-8");}<%= str_anme%>

插入数据是不需要下面的脚本

Java代码

request.setCharacterEncoding("");
