带地图的Struts2多文件上传 [英] Struts2 Multiple File Upload with Map

问题描述

我正在使用Struts2上传多个文件。我使用Java静态动作属性进行映射时，效果很好。但是我正在使用Map来收集所有文件。我只得到文件对象。我没有得到fileName和内容类型。

 
  
公共类TableListAction扩展了ActionSupport 
 {
 private Map raja; 
公共地图getRaja（）
 {
 return raja; 
} 
 public void setRaja（地图raja）
 {
 this.raja = raja; 
} 
 public String upload（）引发异常
 {
 System.out.println（raja）; 
返回成功； 
} 
 
} 
  
 

我的Jsp此

 
  
< s：form enctype = multipart / form-data method = post action = upload> 
< s：file name = raja ['column']>< / s：file> 
< s：file name = raja [’column’]>< / s：file> 
< s：file name = raja [’column’]>< / s：file> 
< s：file name = raja [’column’]>< / s：file> 
< s：submit /> 
  
 

在上传过程中，我在其中获取文件对象数组 raja 映射，但没有获取文件名和内容类型。

在此先感谢

请注意

解决方案

 
  
< s：form enctype = multipart / form-data method = post action = upload> 
< s：file name = raja.column>< / s：file> 
< s：file name = raja.column>< / s：file> 
< s：file name = raja.column>< / s：file> 
< s：file name = raja.column>< / s：file> 
< s：submit /> 
  
 

它们是使用FileName和ContentType附加名称属性。

我在这样的名称之前使用过 raja ['column'] ，因此结果是 raja ['column'] FileName 和
raja ['column'] ContentType 。

然后我修改了 raja.column 。然后它将像 raja.columnContentType 和 raja.columnFileName

一样正确附加FileName和ContentType，现在可以正常工作了。

谢谢

I am doing Multiple file upload with Struts2. It was working fine I map with java static action properties. But I am using Map to collect all the files. I am getting only the file object. I am not getting the fileName and content type.

public class TableListAction extends ActionSupport 
{
    private Map raja;
    public Map getRaja() 
     {
    return raja;
     }
    public void setRaja(Map raja) 
     {
    this.raja = raja;
     }
     public String upload() throws Exception 
     {
        System.out.println(raja);
        return SUCCESS;
    }

} 

My Jsp like this

<s:form enctype="multipart/form-data" method="post" action="upload">
<s:file name="raja['column']"></s:file>
<s:file name="raja['column']"></s:file>
<s:file name="raja['column']"></s:file>
<s:file name="raja['column']"></s:file>
<s:submit/>

During uploading I am getting the file object array in that raja Map but I am not getting the fileName and contenttype.

Thanks in Advance

解决方案

<s:form enctype="multipart/form-data" method="post" action="upload">
<s:file name="raja.column"></s:file>
<s:file name="raja.column"></s:file>
<s:file name="raja.column"></s:file>
<s:file name="raja.column"></s:file>
<s:submit/>

They are append name attribute with FileName and ContentType.

I used before name like this raja['column'], so the result raja['column']FileName and raja['column']ContentType. It wont come into the the Map.

Then i modified raja.column. Then it will append FileName and ContentType correctly like raja.columnContentType and raja.columnFileName

Its work fine now.
Thanks
