I don't know what this exception is? - spring-mvc

Question

This is my Dispatcher codes
#RequestMapping(value="blogWrite", method=RequestMethod.POST)
public ModelAndView writeBlog(BlogText blogText, MultipartFile[] files, HttpSession session) {
System.out.println("writeBlog() 실행");
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("/Blog/BlogPersonal/blogPersonal");
MemberInfo memberInfo = (MemberInfo)session.getAttribute("session");
final String path = "C:/Users/Dongjoo/Downloads/fileUpload/"+memberInfo.getMemberId();
logger.info("path:{}",path);
blogService.addBlogText(modelAndView,blogText,files,path);
return modelAndView;
}
And this is my service layer codes
#Autowired
private BlogDAO blogDAO;
public MemberInfo getMemberLogin(MemberInfo memberInfo) {
MemberInfo takeMemberInfo = blogDAO.memberLogin(memberInfo);
return takeMemberInfo;
}
public ModelAndView addBlogText(ModelAndView modelAndView, BlogText blogText, MultipartFile[] files, final String path) {
System.out.println("addBlogText() 실행");
for(MultipartFile file : files){
File newFile = new File(path+"/"+file.getOriginalFilename());
try {
FileUtils.writeByteArrayToFile(newFile, file.getBytes());
System.out.println("파일 업로드 성공!");
modelAndView.addObject("message", "파일업로드 성공!");
} catch (IOException e) {
e.printStackTrace();
System.out.println("파일 업로드 실패!");
modelAndView.addObject("message", "파일업로드 실패!");
}
}
return modelAndView;
}

Answer 1

Declare CommonsMultipartResolver bean in serlvet configuration.
eg.
For XML config:
--------------
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize">
<value>2097152</value> <!-- 2MB -->
</property>
</bean>
For java config:
---------------
#Bean
public CommonsMultipartResolver multipartResolver() {
return new CommonsMultipartResolver();
}
In Controller annotation use like :
#RequestParam("photo") MultipartFile file
