报表里的内容都是英文的，因为是加拿大的项目，现在我不理解我导出excel为什么乱码那，大家帮忙看看
- Java code
public String branchExcelReport(List list) { JasperPrint jasperPrintArr=null; ArrayList jasperPrintList = new ArrayList(); HttpServletResponse resp=null; JasperReport report; Map map=new HashMap(); String realPath = ""; resp = (HttpServletResponse)ActionContext.getContext().get(org.apache.struts2.StrutsStatics.HTTP_RESPONSE); realPath =ServletActionContext.getServletContext().getRealPath( "/report/template/Branch.jasper"); JRDataSource dataSource = new JRBeanCollectionDataSource(list); try { report = (JasperReport)JRLoader.loadObject(realPath); jasperPrintArr = JasperFillManager.fillReport (report, map, dataSource); jasperPrintList.add(jasperPrintArr); //设定输出格式 FileBufferedOutputStream fbos = new FileBufferedOutputStream(); // 使用JRPdfExproter导出器导出pdf JRPdfExporter exporter = new JRPdfExporter(); // 设置JasperPrintList exporter.setParameter(JRExporterParameter.JASPER_PRINT_LIST, jasperPrintList); exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, fbos); exporter.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE); exporter.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.FALSE); exporter.setParameter(JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE); exporter.exportReport(); resp.reset(); resp.setContentType("application/vnd.ms-excel;charset=UTF-8"); resp.setCharacterEncoding("UTF-8"); resp.setContentLength(fbos.size()); resp.setHeader("Content-Disposition", "attachment; filename=BRANCH.xls"); ServletOutputStream ouputStream = resp.getOutputStream(); try { fbos.writeData(ouputStream); fbos.dispose(); ouputStream.flush(); } finally { if (ouputStream != null) { try { fbos.close(); ouputStream.close(); } catch (IOException ex) { ex.printStackTrace(); } } } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return null;}------解决方案--------------------------------------------------------
ireport的字符格式是不是不是utf-8的？
------解决方案--------------------------------------------------------
resp.setContentType("application/vnd.ms-excel;charset=UTF-8");
resp.setCharacterEncoding("UTF-8");
UTF-8是简体中文，设置成ISO-8859-1试试
------解决方案--------------------------------------------------------
乱码有两种是情况
首先确定编码格式是否正确.
1.为参数没全部传入
2.另外没有让流结束造成的。
如果是Linux下看报表还得在容器启动时加参数。

导出excel不用那么麻烦配置，直接在action中写一个方法就可以实现这个功能
代码：
public String action_executeExcel(){
try{
List<JWJX_JXdajbxx> list = teachDossierService.findAll();
getDmWjlxdmAll();
getDmBgqxAll();
//设置导出头部
HttpServletResponse response = ServletActionContext.getResponse();
response.reset();
response.setContentType("application/vnd.ms-excel");
String fileName = java.net.URLEncoder.encode("教学档案.xls", "UTF-8");
