Question

我有一个代码将MySQL表导出到excel文件。我想导出excel文件，其中包含用户可以理解的列名。我如何设置这些新列名。我的代码如下所示。谢谢。

public Response getEventsAsExcel(@Context HttpServletResponse response) throws Throwable {
    DataReader reader = getEvents();

    ExcelDocument excelDocument = new ExcelDocument();
    DataWriter writer = new ExcelWriter(excelDocument).setFieldNamesInFirstRow(true);

    JobTemplate.DEFAULT.transfer(reader, writer);

    response.setContentType("application/vnd.ms-excel");
    response.setHeader("Content-Disposition", "attachment; filename=\"export.xls\"");
    OutputStream outputStream = response.getOutputStream();
    excelDocument.save(outputStream);

    return Response.ok().build();
}

以下是我正在使用的示例代码。

try {
            response.setContentType("application/vnd.ms-excel");
            String reportName = "excelname_.xls";
            response.setHeader("Content-disposition", "attachment; filename=" + reportName);
            ArrayList<String> rows = new ArrayList<String>();
            rows.add("col1 name");
            rows.add("\t");
            rows.add("col2 name");
            rows.add("\t");
            rows.add("col3 name");
            rows.add("\n");

            for (int i = 0; i < 5; i++) {
                rows.add("col1 data");
                rows.add("\t");
                rows.add("col2 data");
                rows.add("\t");
                rows.add("col3 data");
                rows.add("\n");
            }
            Iterator<String> iter = rows.iterator();
            while (iter.hasNext()) {
                String outputString = (String) iter.next();
                response.getOutputStream().print(outputString);
            }

            response.getOutputStream().flush();

        } catch (IOException e) {
            e.printStackTrace();
        }

您可以使用简单的SQL查询将mysql表导出为excel。

String filename = "d:/outfile.xls";//name of excel file here
String tablename = "abc";//name of table here
stmt.executeQuery("SELECT * INTO OUTFILE \"" + filename + "\" FROM " + tablename);//now execute it.
