Spring Boot doesn't use CommonsMultipartResolver? -

i have problem rest web service running spring boot (jetty). 1 of rest method file upload , i'm guessing commonsmultipartresolver not using during multipart requests.

signature of upload method :

@responsebody @requestmapping(value = "/upload", method = requestmethod.post, produces = "application/json") public baseresponse upload(@requestparam("login") string login, @requestparam("passwd") string passwd,         @requestparam("partner") string partner, @requestparam("filename") string fname,          @requestparam("length") int flen, @requestparam("file") multipartfile file) throws ioexception 

i have root application class below :

@springbootapplication public class bootapplication {      private static final logger _logger = logger.getlogger(bootapplication.class.getname());      public static void main(string[] args) {         springapplication app = new springapplication(bootapplication.class,                 new classpathresource("web-inf/applicationcontext.xml"),                 new classpathresource("web-inf/dispatcher-servlet.xml"));         app.run(args);     }      @bean(name = "multipartresolver")     public commonsmultipartresolver multipartresolver(servletcontext servletcontext) {         _logger.log(level.info, "[bootapplication] fetching commonsmultipartresolver");         return new commonsmultipartresolver(servletcontext);     } } 

when i'm calling method got error :

what's strange in stack trace cannot see commonsmultipartresolver calls. thing same code working in glassfish environment - upload files no problem. changed multipartresolver bean in glassfish defined in dispatcher-servlet.xml , in spring boot initialize in bootapplication class. tried left multipartresolver in dispatcher-servlet.xml i'm loading configuration none of solution worked.

when i'm looking @ /beans endpoint in spring boot can see multipartresolver bean. no other bean has dependency multipartresolver bean - maybe wrong, have no idea how configure properly.

below have dispatcher-servlet.xml if :

<?xml version="1.0" encoding="utf-8"?> <beans xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns="http://www.springframework.org/schema/beans" xsi:schemalocation=" http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">      <context:annotation-config />     <context:component-scan base-package="com.my.package" />     <mvc:annotation-driven /> </beans> 

you using spring boot use it, trying work around it.

spring boot default configures file uploading can remove definition. if want control values can configure adding properties application.properties. see this section of reference guide.

i suggest removing dispatcher-servlet.xml because spring boot enables mvc configuration , enabling interferes auto configuration. assuming bootapplication inside com.my.package can remove file adds nothing, if bootapplication in different package add @componentscan("com.my.package") configuration.

to import applicationcontext.xml add @importresource bootapplication instead of doing now. depending on in there (probably datasource, jpa, etc. configuration might remove , replace simple properties instead).

@springbootapplication @componentscan("com.my.package") @importresource("web-inf/applicationcontext.xml") public class bootapplication {     public static void main(string[] args) throws exception {         springapplication.run(bootapplication.class, args);     } } 

the main problem is disabling part of spring boot auto configuration let configure things.
