struts2上传时报错

zr_dixuexiongying 2013-01-10 12:28:37
我用struts2做的一个上传程序,最后上传时报错,上传的java文件:

package action;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;

import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionSupport;

@SuppressWarnings("serial")
public class MyUpAction extends ActionSupport{
private File upload;
private String uploadContentType;
private String uploadFileName;
private String savePath;
public File getUpload() {
return upload;
}
public void setUpload(File upload) {
this.upload = upload;
}
public String getUploadContentType() {
return uploadContentType;
}
public void setUploadContentType(String uploadContentType) {
this.uploadContentType = uploadContentType;
}
public String getUploadFileName() {
return uploadFileName;
}
public void setUploadFileName(String uploadFileName) {
this.uploadFileName = uploadFileName;
}
@SuppressWarnings("deprecation")
public String getSavePath() throws Exception{
return ServletActionContext.getRequest().getRealPath(savePath);
}
public void setSavePath(String savePath) {
this.savePath = savePath;
}

public String execute() throws Exception{
String fileName = getSavePath() + "\\" + getUploadFileName();
FileOutputStream fos = new FileOutputStream(fileName);
FileInputStream fis = new FileInputStream(getUpload());
byte[] b = new byte[1024];
int len=0;
while((len = fis.read(b))>0){
fos.write(b,0,len);
}
return SUCCESS;
}
}
上传的jsp文件:
<center>
Select upload file:
<s:form action="up" method="post" name="form1" enctype="multipart/form-data" theme="simple">
<s:file name="upload" cssStyle="width:300px;"/>
<s:submit value="submit"/>
</s:form>
</center>

struts.xml文件:
<struts>
<include file="struts-default.xml"/>
<package name="struts2_login" extends="struts-default">
<action name="up" class="action.MyUpAction">
<interceptor-ref name="fileUpload">
<param name="allowedTypes">image/pgn,image/gif,image/jpg</param>
<param name="maximumSize">900000000</param>
</interceptor-ref>
<interceptor-ref name="defaultStack"/>
<param name="savePath">/save</param>
<result name="input">/up.jsp</result>
<result name="success">/success.jsp</result>
</action>
</package>
</struts>

好像是说少了一个临时文件，应该是配置问题（仅供参考）。
Struts2 上传文件 404
如果说配置文件字段名都没有错的话那就是说你的上传的文件超过了4M，而fileupload默认的上传限度为4M！如果没有跟改配置的话那就会抛出异常！而在struts2中则是返回为input！而你又在struts.xml中没有配置/test.jsp所以为出现404！如果先要根治的话！你需要在配置文件中配置一下value的值你可以看着设！最大限度是2G
struts2 文件上传时报错

查看tmp文件夹，发现里面有很多tmp文件，奇怪的是唯独缺少标题以12结尾的这一个，调试总是不出来，
无意中发现自己上传的文件不是正常的pdf，而是我自己用txt文件重命名后改过来做测试用的，所以系统不能
Struts2上传时报临时文件不存在
struts2的上传组件，需要一个临时文件夹，如果不指定，则会默认在work下。当一切都配置好的时候，还是报系统找不到指定文件，我晕，后来发现，奶奶的，上传的文件为空的话就会报此错误，晕死，虽然文件为空不大符合常理，但你管的也太多了吧，就算为空，就保存空的就是了，唉，没办法，只有自己在页面端判断文件的大小，如果为空就警告提示。这算不算是一个bug呢？？？请大家注意一下。   struts配置文...
