是不是文件流没有关闭啊 at com.ving.xzsp.database.ExportExcel.exportExcel(ExportExcel.java:2187) at com.ving.xzsp.database.VicExportExcelServlet.doPost(VicExportExcelServlet.java:44) at com.ving.xzsp.database.VicExportExcelServlet.doGet(VicExportExcelServlet.java:28) 这应该是你程序的报错地方吧查查

可能是没有文件写权限

我就是在这个地方把流给关上才有这个问题的

这个问题解决呢 就是把那个ServletException 的异常给抛出呢 就好呢
