jsp实现下载excel,word,pdf,jgp,gif,xml,js过滤器实现文档.doc

下面代码有选择的粘贴进自己项目即可，其实现解决了tomcat、resin服务器中文下载乱码问题。web.xml配置如下index.jsp downLoad com.tangdi.DownLoadFilter downLoad *.downLoadJsp页面配置如下其下载利用a标签进行连接，前提是服务器上下载文件路径已知需要引进 el表达式和jquery. $(function() var $href=$pageContext.request.contextPath+/20159.downLoad?filePath=;/+encodeURIComponent(中国.downLoad); $(#testHref).children(td).each(function() var $id=$(this).children(:first).attr(id); var $tmpHref=; if($id=txt) $tmpHref=$href+E:/apache-tomcat-6.0.35/apache-tomcat-6.0.35/webapps/MyTry/test/+2031234_这是txt.txt; else if($id=pdf) $tmpHref=$href+E:/apache-tomcat-6.0.35/apache-tomcat-6.0.35/webapps/MyTry/test/+这是pdf.pdf; else if($id=excel) $tmpHref=$href+这是excel.xls; else if($id=word) $tmpHref=encodeURI($href+这是doc.doc,ISO8859-1); else if($id=jpg) $tmpHref=$href+这是jpg.jpg; else if($id=js) $tmpHref=$href+这是js.js; else if($id=jsp) $tmpHref=$href+这是jsp.jsp; else if($id=html) $tmpHref=$href+这是html.html; $(this).children(:first).attr(href,$tmpHref); ); ); txt pdf excel word xml jpg gif js jsp html 过滤器filter配置如下package com.tangdi;import java.io.BufferedInputStream;import java.io.BufferedOutputStream;import java.io.BufferedReader;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.OutputStream;import java.io.PrintWriter;import .URLDecoder;import javax.servlet.Filter;import javax.servlet.FilterChain;import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;public class DownLoadFilter implements Filter public void destroy() public void doFilter(ServletRequest request1, ServletResponse response1,FilterChain arg2) throws IOException, ServletException HttpServletRequest request = (HttpServletRequest) request1;HttpServletResponse response = (HttpServletResponse) response1;/request.setCharacterEncoding(UTF-8);/String filePath = new String(request.getParameter(filePath).getBytes(ISO8859-1), UTF-8);request.setCharacterEncoding(ISO8859-1);String filePath = new String(request.getParameter(filePath).getBytes(ISO8859-1),UTF-8);System.out.println(*filePath is : + filePath);String suffix = filePath.substring(filePath.lastIndexOf(.) + 1);System.out.println(*suffix is:+suffix);String contentType = getContentType(suffix);/获得尾缀设置不同contentTypeString contentDisposition = attachment; filename=+new String(filePath.substring(filePath.lastIndexOf(_)+1);System.out.println(*+contentDisposition);response.setCharacterEncoding(ISO8859-1);response.setContentType(contentType);response.setHeader(Content-disposition, new String(contentDisposition.getBytes(UTF-8),ISO8859-1);try InputStream is = new FileInputStream(filePath);OutputStream os = response.getOutputStream();int byteRead;byte buffer = new byte1024;while (byteRead = is.read(buffer) != -1) os.write(buffer, 0, byteRead);os.flush();os.close(); catch (Exception e) e.printStackTrace();/* * * param suffix 下载文件尾缀 * return 返回不同response.contentType */public String getContentType(String suffix) if (suffix.equals(txt) return text/plain; else if(suffix.equals(doc) | suffix.equals(docx) return application/msword;charset=gb2312; else if(suffix.equals(xls) | suffix.equals(xlsx) return application/-excel; else if(suffix.equals(pdf) return application/pdf;else if(suffix.equals(gif)return image/gif ;else if(suffix.equals(jpg)return image/jpeg ;else if(suffix.equals(htm)|suffix.equals(html)|suffix.equals(jsp)return text/html ;else if(suffix.equals(xml)return text/xml ;else if(suffix.equals(js)return application/x-javas
