I`m going right on this tutorial https://spring.io/guides/gs/uploading-files/ and implemented a multipart file upload controller.
However, stuck on getting this error:
type Exception report
message Request processing failed; nested exception is java.lang.IllegalArgumentException: Expected MultipartHttpServletRequest: is a MultipartResolver configured?
description The server encountered an internal error that prevented it from fulfilling this request.
Here is my code for controller , just right from official tutorial:
package com.springapp.mvc;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
@Controller
public class FileUploadController {
@RequestMapping(value="/api/items/upload_image", method=RequestMethod.POST)
public @ResponseBody String handleFileUpload(@RequestParam("name") String name,
@RequestParam("file") MultipartFile file){
if (!file.isEmpty()) {
try {
byte[] bytes = file.getBytes();
BufferedOutputStream stream =
new BufferedOutputStream(new FileOutputStream(new File(name)));
stream.write(bytes);
stream.close();
return "You successfully uploaded " + name + "!";
} catch (Exception e) {
return "You failed to upload " + name + " => " + e.getMessage();
}
} else {
return "You failed to upload " + name + " because the file was empty.";
}
}
}
And just for additional info, this is how i send request from front-end on angularjs. Request senging successfully:
Upload.upload({
url: '/api/items/upload_image',
file: $file,
name: $file.name,
progress: function(e){}
}).then(function(data, status, headers, config) {
// file is uploaded successfully
console.log(data);
});
What i the problem can be? All needed dependencies included.
This was a solution : include this dependencies in pom.xml
<!-- Apache Commons FileUpload -->
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.1</version>
</dependency>
<!-- Apache Commons IO -->
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>
Add this bean in configuration:
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- setting maximum upload size -->
<property name="maxUploadSize" value="100000" />
</bean>
