修改JSPsmartUpload组件实现无中文乱码上传下载

ServletJSPHTMLWeb浏览器
阅读更多

使用JSPsmartUpload组件上传文件，文件名出现中文字符，下载文件，文件名出现中文字符，都会导致文件名在浏览器出现乱码，自己修改了JSPsmartUpload组件原文件，编译打包成.jar文件。

使用说明：

 

一、解决上传出现乱码问题

  1. 我的WEB项目编码一致为“GBK”，为WEB项目编写一个编码过滤器 
    package com.model.filter;

import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.Filter;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.http.HttpServletRequest;

public class CharacterEncodingFilter implements Filter {

    private FilterConfig config;
    private String encoding = "UTF-8";

    public void init(FilterConfig config) {
        this.config = config;
        String encoding = config.getInitParameter("encoding");
        if (encoding != null) {
            this.encoding = encoding;
            System.out.println("获取编码成功！！");
        } else {
            System.out.println("无法获取编码，采用默认的UTF-8");
        }
    }

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) {
        try {
            HttpServletRequest hrequest = (HttpServletRequest) request;
            hrequest.setCharacterEncoding(this.encoding);
        } catch (UnsupportedEncodingException ex) {
            Logger.getLogger(CharacterEncodingFilter.class.getName()).log(Level.SEVERE, null, ex);
        }
        try {
            chain.doFilter(request, response);
        } catch (IOException ex) {
            Logger.getLogger(CharacterEncodingFilter.class.getName()).log(Level.SEVERE, null, ex);
        } catch (ServletException ex) {
            Logger.getLogger(CharacterEncodingFilter.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

    public void destroy() {
    }
}
     
  2. 过滤器在XML配置文件里需要注册，如下： 
        <filter>
        <filter-name>CharacterEncodingFilter</filter-name>
        <filter-class>com.model.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>gb2312</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
     
  3. 在JSP上传页面，编码设置为“GBK” 
    <%-- 
    Document   : upload
    Created on : 2010-8-5, 18:36:04
    Author     : Gavin
--%>

<%@page contentType="text/html" pageEncoding="gb2312"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
    "http://www.w3.org/TR/html4/loose.dtd">

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
        <title>JSP Page</title>
    </head>
    <body>
        <h1 align="center">Test File Upload</h1>
        <p>
        <form action="upload" enctype="multipart/form-data" name="uploadform" method="post" >
            文件路径1：<br>
            <input type="file" name="file1" size="60" /><br>
            <textarea rows="5" cols="69" name="fileinfo1"></textarea><br>
            <input type="file" name="file2" size="60" /><br>
            <textarea rows="5" cols="69" name="fileinfo2"></textarea><br>
            <input type="submit" value="提交" >&nbsp;&nbsp;
            <input type="reset" value="重置">
        </form>
    </body>
</html>
     

二、在JSPsmartUpload组件中增加下载编码，具体过程不再赘述，提供修改编译打包的.jar文件，可直接使用。
