poi excel文件名或者内容中文乱码

1.文件名乱码处理

		// excel文件名
		String fileName="我报表";
　　　　　　　　　 final SimpleDateFormat formatter = new SimpleDateFormat("yyyyMMddHH24mmssSSS");
		final String formatStr = formatter.format(new Date());
		fileName = fileName + formatStr + "." + fileType;
		System.out.println(fileName);

		final HSSFWorkbook wb = createHSSFWorkbook(map);
		// try {// for testing,created the file in server in path "/home/ap/user/domins/user"
		// final FileOutputStream xlsStream = new FileOutputStream(fileName);
		// wb.write(xlsStream);
		// xlsStream.flush();
		// xlsStream.close();
		// } catch (final Exception e) {
		// e.printStackTrace();
		// }

		// 响应到客户端
		try {
			// 解决文件乱码
			final String userAgent = request.getHeader("user-agent");
			if (userAgent != null && userAgent.indexOf("Firefox") >= 0
					|| userAgent.indexOf("Chrome") >= 0 || userAgent.indexOf("Safari") >= 0) {
				fileName = new String(fileName.getBytes(), "ISO8859-1");
			} else {
				fileName = URLEncoder.encode(fileName, "UTF8"); // 其他浏览器
			}

			// setResponseHeader(response, fileName);

			response.reset();// 清除首部的空白行
			response.setCharacterEncoding("UTF-8");
			response.setContentType("application/vnd.ms-excel;charset=UTF-8");
			response.setHeader("Content-Disposition", "attachment;filename=" + fileName);
			// response.setHeader("Content-Disposition", "inline;filename=" + fileName);
			response.addHeader("Pargam", "no-cache");
			response.addHeader("Cache-Control", "no-cache");
			response.setDateHeader("Expires", 0);
			response.flushBuffer();
			final OutputStream os = response.getOutputStream();
			// os.write(wb.getBytes());
			wb.write(os);
			os.flush();
			os.close();

		} catch (final Exception e) {
			e.printStackTrace();
		}
	}

 2.内容乱码：

tempContent = new String(tempContent.getBytes("UTF-8"), "ISO-8859-1");
                        // System.out.println(tempContent);
tempContent = new String(tempContent.getBytes("ISO-8859-1"), "UTF-8");
cell.setCellValue(tempContent);

3.download.jsp中编码

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page import="java.sql.*" %>
<%@ page import="com.userpackage.*" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
request. setCharacterEncoding("UTF-8");
//response.setHeader("Content-Type", "charset=UTF-8");
%>
<%
out.clear();
out = pageContext.pushBody();
ExcelExport.export(request,response);
%>
