如何上载和更新到DB .xls或.xlsx文件

Question

我使用了JAVA 1.7，Gxt和Oracle 11g以及MyBatis。

到目前为止，我用jxsl做了这个。

XML

<beans>
    <bean id="excelViewByJXLS" class="com.test.UserExcelView">
        <property name="contentType" value="application/vnd.ms-excel; charset=UTF-8"></property>
    </bean>
</beans>

的java

public class UserExcelView extends AbstractExcelView {
    @Override
    protected void buildExcelDocument(Map<String, Object> model,
            HSSFWorkbook workbook, HttpServletRequest request,
            HttpServletResponse response) throws Exception {

        XLSTransformer transformer = new XLSTransformer();
        String templateFileName = "templateFileName";
        String destFileName = "destFileName";
        Workbook resultWorkbook = transformer.transformXLS(new  FileInputStream(templateFileName), model);

        StringBuffer contentDisposition = new StringBuffer();
        contentDisposition.append("attachment;fileName=\"");
        contentDisposition.append(destFileName);
        contentDisposition.append("\";");

        response.setHeader("Content-Disposition", contentDisposition.toString());
        response.setContentType("application/x-msexcel");
        resultWorkbook.write(response.getOutputStream());
    }
}

但是，我无法上传和输入。

我想使用jxsl上传和更新到数据库中。
