配置FileService映射:
dwr.xml
<create creator="new">
<param name="class" value="com.demo.service.FileService"/>
</create>
FileService:
package com.demo.service;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import org.apache.commons.io.FileUtils;
import org.apache.commons.io.FilenameUtils;
import org.directwebremoting.WebContext;
import org.directwebremoting.WebContextFactory;
public class FileService {
public String upload(InputStream inputStream,String fileName) throws IOException{
String tempFileName=FilenameUtils.getName(fileName);
String path=getRealPath("upload");
File file=new File(path+File.separator+tempFileName);
FileUtils.copyInputStreamToFile(inputStream,file);
return file.getPath();
}
public String getRealPath(String dir){
WebContext context=WebContextFactory.get();
return context.getSession().getServletContext().getRealPath(dir);
}
}
upload.jsp:
