web项目文件获取路径:
- controller 里获取
private String realpath = this.getRequest().getSession().getServletContext().getRealPath("/rsa");
- 一般类获取 里获取
public static String thisfile = Thread.currentThread().getContextClassLoader().getResource("").getPath().replace("%20", " "); //配置文件路径
//截取下
thisfile.substring(0, thisfile.indexOf("WEB-INF/classes"))
getRequest().getRealPath("Excel_Model")+ "/dealmb.xls";// 路径 liux可用
//excel模板下载
public void plInsertMuban() {
OutputStream os = null;
try {
String filenames = "批量导入商户信息.xls"; //excel名字
String expenditurepath = getRequest().getRealPath("Excel_Model")+ "/dealmb.xls";// 路径
FileInputStream fs = new FileInputStream(expenditurepath); //模板
HSSFWorkbook workbook = new HSSFWorkbook(new POIFSFileSystem(fs));//创建Excel文档
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-disposition", "attachment;filename="+ new String(filenames.getBytes("gbk"), "iso8859-1"));
os = response.getOutputStream();
workbook.write(os);
os.flush();
os.close();
} catch (Exception e) {
e.printStackTrace();
}finally{
if (os != null) {
try {
os.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
