我的Java Web 应用程序(WebLogic 10.3.5、Spring 3.1和JasperReports 5.0.1)有问题我想导出Excel报告,但在操作结束时,没有出现下载对话框。在Tomcat AS中一切正常,但在WebLogic中不行。
带有导出按钮的 Jsp 代码:
<a title="Export" href="javascript:window.location.replace('<%=path %>/admin/export.com');">Export</a>
Spring MVC 控制器:
@RequestMapping("/export.com")
public ModelAndView exportAction(@ModelAttribute("model") UserModel model, HttpServletRequest request) throws Exception{
SearchBean searchForm = model.getSearchForm();
Map<String,Object> parameterMap = new HashMap<String,Object>();
List<User>usersList = iReportService.getUsers(searchForm,null).getResults();
JRDataSource JRdataSource = new JRBeanCollectionDataSource(usersList);
parameterMap.put("datasource", JRdataSource);
return new ModelAndView("XlsUserReport",parameterMap);
}

在同一个 spring 上下文中,我使用了两个不同的解析器(UrlBasedViewResolver 和 XmlViewResolver),所以这可能会产生问题。
正如我所说,在Tomcat AS中,会出现下载对话框,但是当我在WebLogic中部署我的 Web 应用程序时,导出后单击会出现一个空白页面(URL 是 .../export.com)
