@Configuration
public class SessionConfig implements WebMvcConfigurer{
    
    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        FastJsonHttpMessageConverter fastJsonConverter = new FastJsonHttpMessageConverter();
        FastJsonConfig fjc = new FastJsonConfig();
        SerializeConfig serializeConfig = SerializeConfig.globalInstance;
        serializeConfig.put(Long.class , ToStringSerializer.instance);
        serializeConfig.put(Long.TYPE , ToStringSerializer.instance);
        fjc.setSerializeConfig(serializeConfig);
        fastJsonConverter.setFastJsonConfig(fjc);
        converters.add(fastJsonConverter);
    }
}
