java - Uploading a File fails with Vaadin Spring PLupload-Addon -


if want upload file specific widget/addon of vaadin, im getting warnings , files not uploaded.

i don't have idea, why warning occurres. checking whole addon , saw javascript usage, using post don't why throwing warnings , doesn't work @ all.

i checked addon without spring integration , worked well.

this warnings:

2015-08-16_15:44:53.777 warn  o.s.web.servlet.pagenotfound - request method 'post' not supported 2015-08-16_15:44:53.777 warn  o.s.w.s.m.s.defaulthandlerexceptionresolver - handler execution resulted in exception: request method 'post' not supported 2015-08-16_15:44:54.937 warn  o.s.web.servlet.pagenotfound - request method 'post' not supported 2015-08-16_15:44:54.938 warn  o.s.w.s.m.s.defaulthandlerexceptionresolver - handler execution resulted in exception: request method 'post' not supported 2015-08-16_15:44:55.977 warn  o.s.web.servlet.pagenotfound - request method 'post' not supported 2015-08-16_15:44:55.977 warn  o.s.w.s.m.s.defaulthandlerexceptionresolver - handler execution resulted in exception: request method 'post' not supported 2015-08-16_15:44:57.019 warn  o.s.web.servlet.pagenotfound - request method 'post' not supported 2015-08-16_15:44:57.020 warn  o.s.w.s.m.s.defaulthandlerexceptionresolver - handler execution resulted in exception: request method 'post' not supported 

my code following, simple init() minimum of functionallity:

protected void init (vaadinrequest request){     horizontallayout root = new horizontallayout();     root.setsizefull();     setcontent(root);     setsizefull();      pluploadmanager manager = new pluploadmanager();     manager.getuploader().setmaxfilesize("10mb");     manager.getuploader().addfileuploadedlistener(new plupload.fileuploadedlistener() {         public void onfileuploaded(pluploadfile file) {             notification.show("i've uploaded file: " + file.getname());         }     });      manager.getuploader().adderrorlistener(new plupload.errorlistener() {         public void onerror(pluploaderror error) {             notification.show("there error: " + error.getmessage() + " (" + error.gettype() + ")",                     notification.type.error_message);         }     });      root.addcomponent(manager); } 

here dependencies inside pom:

<dependency>     <groupid>org.springframework.boot</groupid>     <artifactid>spring-boot-starter-data-rest</artifactid> </dependency> <dependency>     <groupid>com.vaadin</groupid>     <artifactid>vaadin-spring-boot-starter</artifactid>     <version>1.0.0.beta3</version> </dependency> <dependency>     <groupid>pl.exsio</groupid>     <artifactid>plupload-vaadin</artifactid>     <version>2.0.0</version> </dependency> 

current technolgies:

that not supported out of box.

the reason url /pluploader-upload-action not being processed vaadin's servlet. real url of vaadin's servlet /vaadinservlet. vaadin registers simpleurlhandlermapping servletforwardingcontroller on root url (by default) , /vaadin. other urls, need register them yourself.

try workaround.

in application.properties:

multipart.enabled=false 

add following configuration.

@configuration public class vaadinpluploadconfiguration {   private static final string pluploader_url = "/pluploader-upload-action";   @inject   private controller vaadinuiforwardingcontroller;    @bean   public simpleurlhandlermapping vaadinforwardinghandlermapping() {     simpleurlhandlermapping mapping = new simpleurlhandlermapping();     mapping.setorder(integer.min_value + 1);     map<string, object> urlmappings = new hashmap<string, object>();     urlmappings.put(pluploader_url, vaadinuiforwardingcontroller);     mapping.seturlmap(urlmappings);     return mapping;   } } 

the multipart disabled allow plupload add-on process multipart section otherwise processed spring , break add-on.
