I am using Spring Boot to test a upload functionality, and getting
'Required MultipartFile parameter 'file' is not present'
error. Following are the 1) JSP, 2) Controller 3) Config Class 4) embedded tomcat log.
JSP page
----------------------------------------------------------------------------
<!DOCTYPE html>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html lang="en">
<body>
<br>Message: ${message}
<h2>List Of Objects</h2>
<br>
<h2>Upload New File to this Bucket</h2>
<form action="uploadObject" method="post" enctype="multipart/form-data">
<table width="60%" border="1" cellspacing="0">
<tr>
<td width="35%"><strong>File to upload</strong></td>
<td width="65%"><input type="file" name="file" /></td>
</tr>
<tr>
<td> </td>
<td><input type="submit" name="submit" value="Add" /></td>
</tr>
</table>
</form>
</body>
</html>
2. Controller:
@RequestMapping(value = "/uploadObject", method = RequestMethod.POST)
@Override
public String upload(@RequestParam("file") MultipartFile file,
@RequestParam("bucketName") String bucketName,
Map<String, Object> model) {
LOG.info("Object name parameter is " + file.getOriginalFilename());
LOG.info("Bucket name parameter is " + bucketName);
....
}
3) Config Class:
package com.phi.piranha.client.config;
import javax.servlet.MultipartConfigElement;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.embedded.MultiPartConfigFactory;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.multipart.commons.CommonsMultipartResolver;
@Configuration
@EnableAutoConfiguration
@ComponentScan("com.phi.piranha")
public class PiranhaStorageServiceClientApplication extends
SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(
final SpringApplicationBuilder application) {
return application
.sources(PiranhaStorageServiceClientApplication.class);
}
@SuppressWarnings("PMD.SignatureDeclareThrowsException")
public static void main(final String[] args) throws Exception {
SpringApplication.run(PiranhaStorageServiceClientApplication.class,
args);
}
@Bean
MultipartConfigElement multipartConfigElement() {
MultiPartConfigFactory factory = new MultiPartConfigFactory();
factory.setMaxFileSize("1024KB");
factory.setMaxRequestSize("1024KB");
return factory.createMultipartConfig();
}
@Bean
CommonsMultipartResolver multipartResolver(){
return new CommonsMultipartResolver();
}
}
