    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&amp;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">
