在WebConfig内加入

@Bean//使用@Bean注入fastJsonHttpMessageConvert
    public HttpMessageConverter fastJsonHttpMessageConverters() {
        //1.需要定义一个Convert转换消息的对象
        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
        fastJsonConfig.setDateFormat("yyyy-MM-dd HH:mm:ss");


        //防止中文乱码
        ArrayList<MediaType> supportedMediaTypes = new ArrayList<>();
        supportedMediaTypes.add(MediaType.APPLICATION_JSON);
        fastConverter.setSupportedMediaTypes(supportedMediaTypes);

        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());
    }

下面这一段就是为了解决中文乱码问题

//防止中文乱码
        ArrayList<MediaType> supportedMediaTypes = new ArrayList<>();
        supportedMediaTypes.add(MediaType.APPLICATION_JSON);
        fastConverter.setSupportedMediaTypes(supportedMediaTypes);

MediaType.APPLICATION_JSON_UTF8已过时
