struts2 文件上传问题 临时文件夹的 探讨
我用的是eclipse j2ee web 开发版！
此问题纠结了半天了、、、据说是路径的问题我用\ /都试了，好像没处在这上面、、、不知其什么原因、、、各位帮帮看看
struts.xml
<constant name="struts.multipart.saveDir" value="\tmp"></constant>
<constant name="struts.mutilpart.maxSize" value="1024000"></constant>
<package name="upload" extends = "struts-default">
<action name="upload" class = "org.leno.struts2.action.UploadAction">
<interceptor-ref name="fileUpload">
<param name="maxinmumSize">1024000</param>
<param name="allowedTypes">text/plain</param>
</interceptor-ref>
<interceptor-ref name="defaultStack" ></interceptor-ref>
<result name="success">/success.jsp</result>
<result name= "input">/singleUpload.jsp</result>
</action>
</package>
UploadAction.java 为：
private File upload ;
private String uploadFileName;
private String uploadContentType;
、、、、、、
String newroot = ServletActionContext.getServletContext().getRealPath("/upload");
System.out.println(newroot);
File dir = new File(newroot,getUploadFileName());
FileInputStream input = new FileInputStream(getUpload());
FileOutputStream output = new FileOutputStream(dir);
byte[] buf = new byte[100];
int len = 100;
while((len = input.read())>=0)
{
output.write(buf, 0, len);
}
input.close();
output.close();
问题是：
