问如何在spring-web servlet中接受text/csv作为内容类型？

EN

@RestController
public class MyServlet {
    @PostMapping(produces = {"text/csv", "application/json"})
    public Object post() {
        //...
    }
}

spring.mvc.contentnegotiation.media-types.csv=text/csv

@Configuration
public class ContentNegotiationConfiguration implements WebMvcConfigurer {
    @Override
    public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
        configurer
                .favorParameter(true) //favor &format=csv
                .defaultContentType(MediaType.APPLICATION_JSON)
                .parameterName(format);
                //.mediaType("csv", new MediaType("text", "csv")) //also tried without success
    }
}
