spring boot webflux json序列化疑问

Question

遇到的问题：使用spring-boot-starter-webflux开发的时候使用默认的jackson做JSON的序列化与反序列化，但是当我的javaBean里的属性使用的是驼峰命名法，我想序列化成JSON字符串后得到匈牙利命名法的json key, 但是失败了，这是我的配置代码

    @Bean
    public MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter() {
        MappingJackson2HttpMessageConverter jsonConverter = new MappingJackson2HttpMessageConverter();
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setPropertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);
        jsonConverter.setObjectMapper(objectMapper);
        return jsonConverter;
    }

请问这是为什么呢？

Based on spring boot Javadoc, a bean of type JacksonHttpMessageConvertersConfiguration needs an injected ObjectMapper object, thereafter, all you need is to define a bean of type ObjectMapper, like this：

@Bean
ObjectMapper yourMethod() {...}

Please note that, this ObjectMapper would be used for all spring de/serialization, if you want to customize only some properties or some Pojos, use the corresponding jackson annotations, which is off the topic.
