Configuration:

    @Bean
    public CommonsMultipartResolver multipartResolver() {
        CommonsMultipartResolver resolver=new CommonsMultipartResolver();
        resolver.setDefaultEncoding("utf-8");
        return resolver;
    }

Controller code:

@RequestMapping(method = RequestMethod.POST)
    public void addQuestion(@RequestParam MultipartFile script,
                            @RequestParam MultipartFile answerTemplate,
                            @RequestParam DataSourceType dataSourceType,
                            @RequestParam DataType dataType,
                            @RequestParam ScriptType scriptType,
                            @RequestParam List<Tag> tags,
                            @RequestParam(required = false) String dataSourceResource){

        Question question = new Question(tags, dataSourceType, dataSourceResource, dataType, scriptType);
        questionHelper.saveQuestion(question, script, answerTemplate);

    }

    @RequestMapping(value = "/{id}", method = RequestMethod.PUT)
    public void updateQuestion(@PathVariable Integer id,
                               @RequestParam(required = false) MultipartFile script,
                               @RequestParam(required = false) MultipartFile answerTemplate,
                               @RequestParam(required = false) DataSourceType dataSourceType,
                               @RequestParam(required = false) DataType dataType,
                               @RequestParam(required = false) ScriptType scriptType,
                               @RequestParam(required = false) List<Tag> tags,
                               @RequestParam(required = false) String dataSourceResource){
        Question question = new Question(tags, dataSourceType, dataSourceResource, dataType, scriptType);
        questionHelper.updateQuestion(id, question, script, answerTemplate);
    }

Answer 1

The answer is that CommonsMultipartResolver support only POST. It can work with other methods but when it checks if request is multipart it checks method and only POST allowed. The solution is extends this resolver and override method that checks to allow other http methods.

Answer 2

In your configuration try to change the bean method to:

 @Bean("multipartResolver")
 public CommonsMultipartResolver multipartResolver(){
