import java.io.File;
import java.io.IOException;

import javax.servlet.ServletContext;
import javax.servlet.http.HttpSession;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.servlet.ModelAndView;

/**

*/
@Controller
public class FileUpload {

@RequestMapping("fileUploadPage")//对应页面传来的action
public ModelAndView fileUpload(@RequestParam("file") MultipartFile file1,HttpSession session) throws Exception, IOException {
ModelAndView mav=new ModelAndView();
if (file1.isEmpty()) {
mav.setViewName("fail.html");
}else {
File tempFile=new File(session.getServletContext().getRealPath(".")+"/"+file1.getOriginalFilename());
if (!tempFile.exists()) {
tempFile.createNewFile();
}
file1.transferTo(tempFile);//写入文件
System.out.println(session.getServletContext().getRealPath("")+"/"+file1.getOriginalFilename());
System.out.println(tempFile.getAbsolutePath());
mav.setViewName("success");
}
// @RequestParam("name") String name,
//mav.addObject("name", name);
return mav;
}

}
