使用HttpServlet彈出下載excel

我想下載創建的excel文件。我正在使用POI。此北京時間我的代碼：使用HttpServlet彈出下載excel

response.setContentType("application/vnd.ms-excel"); 
    response.setHeader("Content-Disposition", "attachment; filename=" + filename); 

    OutputStream out = response.getOutputStream(); 

    HSSFWorkbook workbook = new HSSFWorkbook(); 
    ... // add some sheets 


    workbook.write(out);

這是我RestService

@Autowired 
Excel excel; 

@RequestMapping(path = "/excel/{testId}", method = RequestMethod.GET) 
public ResponseEntity createFile(HttpServletResponse response, @PathVariable Integer testId) { 


    try { 
     excel.createFile(response, testId); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

    return new ResponseEntity(HttpStatus.OK); 


}

這是結果：

存儲文件的本地作品。

謝謝！

您需要提供比這更多的代碼。你如何創建工作簿？你的spring控制器或servlet的完整方法是什麼？ –

嘿我編輯我的答案希望它會幫助 – 1thingtodo

需要設置的HttpResponse對象

例

適當的值對於.xls文件

response.setHeader（「內容類型」，應用程序/ vnd.ms-EXCEL） ;

response.setCharacterEncoding（「UTF-8」）;

對於Excel2007中和上述的.xlsx文件

response.setCharacterEncoding（「UTF-8」）;

response.setHeader（「Content-Type」，「application/vnd.openxmlformats-officedocument.spreadsheetml.sheet」）;

下面是使用Spring MVC的

1.創建AS-IS POJO類（或域類）

public class Person{ 

private String name; 

private int age; 

//Getters and Setters 
}

2〜下載Excel文件的步驟。創建服務類並擴展AbstractExcelView類

public class MyExcelServiceClass extends AbstractExcelView{ 

     @Override 
     protected void buildExcelDocument(Map model, HSSFWorkbook workbook, 
      HttpServletRequest request, HttpServletResponse response) 
      throws Exception { 

      //Now you have Excel WorkBook Object available for processing Excel file using POI API 

     }

}
