jsp编码问题

jsp编码问题

方法一%%%%%%%%%%%%%%%%%%%%%%%%%
例：1:jsp页面用<%@ page language="java" pageEncoding="UTF-8"%>
   2: mysql数据库utf8(没问题)
3:mysql链接字符串

<property name="url">
    <value>jdbc:mysql://127.0.0.1:3306/cms?useUnicode=true&characterEncoding=UTF-8</value>
</property>
4:
   出现问题:jsp页面数据一传到mysql数据库里就变成乱码
   最后解决方法:把对传递的数据值的变量操作如下:
   String username=StringEncode.getEncode(userForm.getUsername());

StringEncode.getEncode的功能如下:

package com.links.utils;

public class StringEncode {

    public static String getEncode(String str)
    {
    String ret;

    if(str==null)
        return str;
    try{
        // ret=new String(str.getBytes("UTF-8"),"UTF-8");
        ret=new String(str.getBytes("ISO-8859-1"),"UTF-8");

    }
    catch(Exception e){

        ret=str;
    }
    return ret;
    }

}
其它参考

方法二%%%%%%%%%%%%%%%%%%%%%%%%%(为了不都写 StringEncode.getEncode转换)

就是要在web.xml配置如下:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
