导入EXCEL表,按照要求生成了数据库(用的NUTZ的J4E),现在想把修改的表重数据库中导出,单用J4E总体工的导出步骤报错:

public Object downloadfile(HttpSession session)
    {
        List<subpon> subPon = dao.query(subpon.class, null);  
 
      
      J4E.<subpon>toExcel(Files.createFileIfNoExists2("d:\\人员.xls"),subPon,null);  
        return "ok";
    }

报FILE不能转化成OUTPUTSTREAM,怎么玩?

75 回复

贴完整报错信息

是不是还缺了什么?

编译通不过啊

按ALT+ENTER,显示FILE不能转换成OUTPUTSTREAM

你用的不是快照版? 使用File参数的toExcel方法的名字, 原本是错误的"toExce", 在快照版中修正回toExcel

https://github.com/nutzam/nutzmore/commit/2f7ef692dae54471e822dfcb157d558d39b96051

就是上次你给我的连接啊

谢谢,修改一下网页的步骤说明吧

我参照网页的步骤做的

应该是版本问题,能否发个正确的版本给我,谢谢

谢谢,我的项目结题了,唉呀,可以睡觉了,谢谢

... 擦, 你这是通宵了?

差不多,不完成不罢休,老大的要求

晕啊,本以为万事大吉,结果出现啊了新问题:导出的表格我lock了ID和另外一个字段,但导出的表格中有这两个字段的标题,id字段为0,另外一个字段有标题无内容,要求不能有这两个字段,怎么玩?

在不

嗯, 需要找一下胖五

不导出的字段 上面加上 @J4EIgnore

谢谢,立马试试

来自炫酷的 NutzCN

这两个字段在原表中没有,只是为了在编程中方便,加入,我试了加这个参数,还是一样

pojo贴一下看看?

ID和GH都在原表中无

我在做公司的割接EXCEL表的导入导出

手机的NUTCN打开的话题不自动更新,需刷新

用的是最新的jar包吗,需要最新版的

我下了.65的JAR

public Object downloadfile(HttpSession session)
    {
     SimpleDateFormat sdf=new SimpleDateFormat("yyyyMMddhhmmss");  
       
     String str=sdf.format(new Date());  
     String filename="d:\\PON口割接导出文件\\PON口割接_"+session.getAttribute("gh")+"_"+str+".xls";
    
     List<subpon> subPon =Daos.ext(dao, FieldFilter.locked(subpon.class, "^id|gh$")).query(subpon.class, Cnd.where("gh","=",session.getAttribute("gh")));  
    
      J4E.<subpon>toExcel(Files.createFileIfNoExists2(filename),subPon,null);  
        return "ok";
    }

下个最新的试试,@J4EIgnore这个之前不知为啥不被删了,前两天刚刚把逻辑加回来 最新的才行

万岁,万岁,可以了

我打赏了,不多,谢谢

两个都有,谢谢

有点奇怪,我想增加判断文件是否成功,吧这个语句J4E.toExcel(Files.createFileIfNoExists2(filename),subPon,null);的返回值用了一下,明明文件已成功得到,没有错,怎么返回FALSE,这个FALSE是指什么有问题?

那是是否新建的意思吧

应该不是,我在服务器上的文件是新建的,原来文件在客户端

来自炫酷的 NutzCN

你的意思是toExcel的返回值是false?导出失败?

导出是成功的,服务器对应的目录有文件,但这个函数返回false

来自炫酷的 NutzCN

翻了翻代码, 应该是IO错误才会返回false吧, debug一下?

你是不是总是写到同一个文件了??? 用我这种写法吧

try (OutputStream out = new FileOutputStream(Files.createFileIfNoExists2("/tmp/"+R.UU32()+".xls"))) {
    J4E.toExcel(out, people, null);  
}

是我搞错了,当导出数据为0条时报错,这个是正常的,谢谢

@wendal 大佬
controller方法的@OK 怎么写 然后那个文件 在哪找啊

@wendal 为什么 出来的格式不是我想要的 好像是json

导出来是这种形式的 我加那个注解了

你得自行生成xls文件, 例如用J4E等工具库, nutz本身是不会帮你转的

这句话不是生成xls么。

J4E.toExcel(out, t_ieo_playings, null);  

然后得把file对象作为返回值呀,上代码吧

  try (OutputStream out = new FileOutputStream(Files.createFileIfNoExists2("~/打币列表.xls"))) {
            J4E.toExcel(out, t_ieo_playings, null);
        }
        catch (Exception e){
            e.printStackTrace();
        }

w我就这么写的。

   File f = Files.createFileIfNoExists2("~/打币列表.xls");
  try (OutputStream out = new FileOutputStream(f)) {
            J4E.toExcel(out, t_ieo_playings, null);
        }
        catch (Exception e){
            e.printStackTrace();
        }
   return f;

@wendal 大佬啊 还有个问题 我前台是这样传过来的

 location.href="${base}/platform/ieo/playing/exportExcel"+param;

这样不会有问题么 我每次都是转到一个空白页

当前的入口方法是怎样的? 有没有进入口方法?

controller这样写的

 @At("/exportExcel1")
    @Ok("raw")
    @RequiresPermissions("ieo.order.index")
    public Object exportExcel1(@Param("name") String name,
                            @Param("status") String status,
                            @Param("coin_name") String coin_name,
                            @Param("beginDate") String beginDate,
                            @Param("endDate") String endDate,
                            @Param("currency") String currency,
                            @Param("start") int start,
                            @Param("::order") List<DataTableOrder> order,HttpServletResponse response) throws IOException {

进去了 也没报错 就是 转到空白页

有没有进入口方法?

有没有return file呀

这些不是DataTables的参数么? 用来下载文件??

  List<T_ieo_playing> t_ieo_playings =  tIeoPlayingService.exportExcel1(conditionStr);
        File f = Files.createFileIfNoExists2("~/打币列表.xls");
        try (OutputStream out = new FileOutputStream(f)) {
            J4E.toExcel(out, t_ieo_playings, null);
        }
        catch (Exception e){
            e.printStackTrace();
        }
        return f;

那些事条件查询带过来的 dao层 写的自定义sql

文件生成了没,内容对不对

文件生成了 但是 数据还是不对

  @J4EName("项目名称")
    private String project_name;

实体这么写 对么
