使用Spring MockMvc 测试spring mvc 生成的EXCEL

1. SPRING MVC 生成EXCEL

@RequestMapping(value = "/requestFileByJson", method = RequestMethod.POST)
	public void  getListByCallFunction(
			@RequestBody String data,
			 HttpServletRequest request,
			HttpServletResponse response, HttpSession session) throws Exception {


response.setContentType("application/ms-excel;charset=UTF-8");
			response.setHeader("Content-Disposition","attachment;filename=".concat(String.valueOf(URLEncoder.encode(systemID + "_"+JName+".xls", "UTF-8"))));	
			OutputStream out = response.getOutputStream();
			
			String sheetName = "导出WEBEDI";
			String titleNames = null;
			resultMapList = new ArrayList();
			HSSFWorkbook excel = excelWordService.getExcelByDataMap(resultMapList,sheetName,titleNames);				
			excel.write(out);  
                        out.flush();

}

2. 使用MockMvc 进行测试生成的EXCEL

@Test
	public void testInserOneLine() throws Ex
