Spring boot - setting default Content-type header if it's not present in request

I'm having the following problem: suppose I sometimes receive POST requests with no Content-type header set. In this case I want to assume that Content-type=application/json by default.

Can I achieve this somehow using spring boot features and not using filters?

Thanks

As of Spring Boot 2.x, you need to create a class that extends the WebMvcConfigurer interface, e.g.:

@Configuration
class WebMvcConfiguration implements WebMvcConfigurer {
    @Override
    public void configureContentNegotiation( ContentNegotiationConfigurer configurer )
    {
        configurer.defaultContentType( MediaType.APPLICATION_JSON );
    }
}

Under 1.x, you could do the same thing with WebMvcConfigurerAdapter, which is now deprecated.

This will affect both request and response bodies, so if you do not have a "produces" parameter explicitly set, and you wanted something other than application/json, it's going to get coerced to application/json.
