play框架生成excel解决zip压缩问题

无需引入依赖，使用的是org.apache.poi

遇到的一些问题：

1、下载的excel文件为zip

zip文件目录如下，修改后缀为xls后为正确的表格

解决方法，加上配置信息或者renderBinary方法加上文件名称

我做的是访问接口后直接下载文件，下载结果：

package controllers;

    public void getExcel() {
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        File exportFile = null;
        FileInputStream fileInputStream = null;
        XSSFWorkbook workbook = new XSSFWorkbook();
        //查询出要插入excel的数据
        List<MysqlEnterprisesQichacha> mysqlEnterprisesQichachaList = MysqlEnterprisesQichacha.find("").fetch(10);
        String fileName = "test";
        try {
            XSSFSheet sheet = workbook.createSheet();
 
            // 创建头部信息行和单元格
            XSSFRow headerRow = sheet.createRow(0);
            headerRow.createCell(0).setCellValue("标题");
            headerRow.createCell(1).setCellValue("行业");

            headerRow.createCell(6).setCellValue("正文");
            mysqlEnterprisesQichachaList.stream().forEach(mysqlEnterprisesQichacha -> {
 
                XSSFRow dataRow = sheet.createRow(mysqlEnterprisesQichachaList.indexOf(mysqlEnterprisesQichacha)+1);
                dataRow.createCell(0).setCellValue(mysqlEnterprisesQichacha.getId_zbw());
                dataRow.createCell(1).setCellValue(mysqlEnterprisesQichacha.getComid_zbw());
                dataRow.createCell(2).setCellValue(mysqlEnterprisesQichacha.getComname());
                dataRow.createCell(3).setCellValue(mysqlEnterprisesQichacha.getCreate_time());
                dataRow.createCell(4).setCellValue(mysqlEnterprisesQichacha.getResult());
                dataRow.createCell(5).setCellValue(mysqlEnterprisesQichacha.getResult());
                dataRow.createCell(6).setCellValue(mysqlEnterprisesQichacha.getResult());
            });
            //写入表格数据
            workbook.write(byteArrayOutputStream);
 
            exportFile = new File(file_path + "app/controllers/"+fileName+".xlsx");
            if (!exportFile.exists()) {
                exportFile.createNewFile();
            }
            FileOutputStream fileOut = new FileOutputStream(exportFile);
            fileOut.write(byteArrayOutputStream.toByteArray());
            fileOut.close();
            fileInputStream = new FileInputStream(exportFile);
 
        } catch (IOException e) {
            Logger.info("文件转换异常：{}", e);
        }
        //如果导出文件为zip，可以加上以下注释代码，当renderBinary方法没有添加name参数时需要加上
//        response.setContentTypeIfNotSet("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
        renderBinary(fileInputStream,fileName+".xls");
 
    }
}

我在文件上传后某个空间，然后再进行下载时出现了zip问题未解决！！
