MockMvc no longer handles UTF-8 characters with Spring Boot 2.2.0.RELEASE

Yes. This is problem from 2.2.0 spring-boot. They set deprecation for default charset encoding.

.getContentAsString(StandardCharsets.UTF_8) – good but in any response would be populated ISO 8859-1 by default.

In my project I updated current created converter:

@Configuration
public class SpringConfig implements WebMvcConfigurer {

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.stream()
            .filter(converter -> converter instanceof MappingJackson2HttpMessageConverter)
            .findFirst()
            .ifPresent(converter -> ((MappingJackson2HttpMessageConverter) converter).setDefaultCharset(UTF_8));
    }
