This code snippet defines a method that configures the use of FastJson as the HTTP message converter. It sets up the serialization features, date format, and serialization configuration. The method is then added to the list of message converters to be used.

    @Bean// Use @Bean to inject fastJsonHttpMessageConvert
    public HttpMessageConverter fastJsonHttpMessageConverters() {
        // 1. Need to define an object for converting messages
        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        fastJsonConfig.setDateFormat("yyyy-MM-dd HH:mm:ss");
		
        SerializeConfig.globalInstance.put(Long.class, ToStringSerializer.instance);

        fastJsonConfig.setSerializeConfig(SerializeConfig.globalInstance);
        fastConverter.setFastJsonConfig(fastJsonConfig);
        HttpMessageConverter<?> converter = fastConverter;
        return converter;
    }

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.add(fastJsonHttpMessageConverters());
    }
