框架默认提供基于fastJosn的HttpMessageConverters实现,默认情况下关闭

代码实现

    @Bean
    @ConditionalOnProperty(value = "xy.core.http.message.converter.enable", havingValue = "true")
    public HttpMessageConverters httpMessageConverters() {
        //1、创建FastJson信息转换对象
        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
        //2、创建FastJsonConfig对象并设定序列化规则  序列化规则详见SerializerFeature类中，后面会讲
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(
                SerializerFeature.QuoteFieldNames,
                SerializerFeature.WriteMapNullValue,
                SerializerFeature.DisableCircularReferenceDetect,
                SerializerFeature.WriteDateUseDateFormat,
                SerializerFeature.WriteNullStringAsEmpty
        );
        //本人就坑在WriteNonStringKeyAsString 将不是String类型的key转换成String类型，否则前台无法将Json字符串转换成Json对象
        //3、中文乱码解决方案
        List<MediaType> fastMediasTypes = new ArrayList<MediaType>();
        fastMediasTypes.add(new MediaType(MediaType.APPLICATION_JSON, Charset.forName("UTF-8")));
        fastConverter.setSupportedMediaTypes(fastMediasTypes);
        //4、将转换规则应用于转换对象
        fastConverter.setFastJsonConfig(fastJsonConfig);
        log.info("loading HttpMessageConverters............");
        return new HttpMessageConverters(fastConverter);
    }

开发配置

xy.core.http.message.converter.enable=true
