Java SpringMVC抽象视图

我尝试使用spring的AbstractXlsxView，但它只是提示下载应用程序/八位字节流文件类型，而不是excel文件

ExcelBuilder.java

public class ExcelBuilder extends AbstractXlsxView {

    @Override
    protected void buildExcelDocument(Map<String, Object> model,
            Workbook workbook, HttpServletRequest request,
            HttpServletResponse response) throws Exception {

        Sheet latePaymentsSheet = workbook
                .createSheet("Late Payments");
        setLatePaymentHeader(latePaymentsSheet);

        @SuppressWarnings("unchecked")
        Map<String, Object> map = (Map<String, Object>) model.get("map");
        @SuppressWarnings("unchecked")
        List<Map<String, Object>> latePaymentsList = (List<Map<String, Object>>) map
                .get("latePayments");

        setLatePaymentsRow(latePaymentsSheet, latePaymentsList);
    }

@RequestMapping(value = "/export", method = RequestMethod.GET)
public ModelAndView exportToExcel() {

    Map<String,Object> map = Dao.getData()

 return new ModelAndView("ExcelBuilder", "map", map);
}

公共类ExcelBuilder扩展了AbstractXlsxView{
@凌驾
受保护的文档（地图模型，
工作簿，HttpServletRequest请求，
HttpServletResponse）引发异常{
工作表延迟付款工作表=工作簿
.createSheet（“逾期付款”）；
设置LatePaymentHeader（latePaymentsSheet）；
@抑制警告（“未选中”）
Map=（Map）model.get（“Map”）；
@抑制警告（“未选中”）
列表latePaymentsList=（列表）映射
.获得（“延期付款”）；
设置LatePaymentsRow（latePaymentsSheet，latePaymentsList）；
}

Controller.java

public class ExcelBuilder extends AbstractXlsxView {

    @Override
    protected void buildExcelDocument(Map<String, Object> model,
            Workbook workbook, HttpServletRequest request,
            HttpServletResponse response) throws Exception {

        Sheet latePaymentsSheet = workbook
                .createSheet("Late Payments");
        setLatePaymentHeader(latePaymentsSheet);

        @SuppressWarnings("unchecked")
        Map<String, Object> map = (Map<String, Object>) model.get("map");
        @SuppressWarnings("unchecked")
        List<Map<String, Object>> latePaymentsList = (List<Map<String, Object>>) map
                .get("latePayments");

        setLatePaymentsRow(latePaymentsSheet, latePaymentsList);
    }

@RequestMapping(value = "/export", method = RequestMethod.GET)
public ModelAndView exportToExcel() {

    Map<String,Object> map = Dao.getData()

 return new ModelAndView("ExcelBuilder", "map", map);
}

@RequestMapping（value=“/export”，method=RequestMethod.GET）
公共模型和视图exportToExcel（）{
Map Map=Dao.getData（）
返回新的ModelAndView（“ExcelBuilder”、“地图”、“地图”）；
}

Excel view.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans

    <bean id="ExcelBuilder" class="com.test.utility.ExcelBuilder">

</beans>

您可以更改@RequestMapping并添加

products

属性

@RequestMapping(value = "/export", method = RequestMethod.GET, produces="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")

有关其他Mime类型，请参阅。

您可以设置文件类型作为响应，如下所示：

public ModelAndView exportPaymentReport(HttpServletResponse response) {
     response.setContentType( "application/ms-excel" );
     response.setHeader( "Content-disposition", "attachment;filename=myfile.xls" );
}
