Add this <i>Bean</i> in your webconfig class
@Bean
public ContentNegotiatingViewResolver contentViewResolver() {
ContentNegotiationManagerFactoryBean contentNegotiationManager = new ContentNegotiationManagerFactoryBean();
contentNegotiationManager.addMediaType("json", MediaType.APPLICATION_JSON);
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/jsp/");
viewResolver.setSuffix(".jsp");
MappingJackson2JsonView defaultView = new MappingJackson2JsonView();
defaultView.setExtractValueFromSingleKeyModel(true);
ContentNegotiatingViewResolver contentViewResolver = new ContentNegotiatingViewResolver();
contentViewResolver.setContentNegotiationManager(contentNegotiationManager.getObject());
contentViewResolver.setViewResolvers(Arrays.<ViewResolver> asList(viewResolver));
contentViewResolver.setDefaultViews(Arrays.<View> asList(defaultView));
return contentViewResolver;
}
**UPDATE**
The guys from the comments are right, this won't fix your issue but I noticed something.
If I set consumes = MediaType.APPLICATION_JSON_VALUE and in the request I don't specify the content type it will throw an exception then if I set the content type the issue is fixed.
Now, the issue seems to be something with your dependencies.
