springboot @JSONField注解失效解决方案

实现WebMvcConfigurer接口，重

 @Configuration
public class ResourcesConfig implements WebMvcConfigurer
{
    @Autowired
    private RepeatSubmitInterceptor repeatSubmitInterceptor;

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry)
    {
        /** 本地文件上传路径 */
        registry.addResourceHandler(Constants.RESOURCE_PREFIX + "/**").addResourceLocations("file:" + RuoYiConfig.getProfile() + "/");

        /** swagger配置 */
        registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
    }

    /**
     * 自定义拦截规则
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry)
    {
        registry.addInterceptor(repeatSubmitInterceptor).addPathPatterns("/**");
    }

    /**
     * 跨域配置
     */
    @Bean
    public CorsFilter corsFilter()
    {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        // 设置访问源地址
        config.addAllowedOrigin("*");
        // 设置访问源请求头
        config.addAllowedHeader("*");
        // 设置访问源请求方法
        config.addAllowedMethod("*");
        // 对接口配置跨域设置
        source.registerCorsConfiguration("/**", config);
        return new CorsFilter(source);
    }


    @Override
    public void configureMessageConverters(List> converters) {
        // 清除默认 Json 转换器
        converters.removeIf(converter -> converter instanceof MappingJackson2HttpMessageConverter);

        // 配置 FastJson
        FastJsonConfig config = new FastJsonConfig();
        config.setSerializerFeatures(SerializerFeature.QuoteFieldNames,
                SerializerFeature.WriteEnumUsingToString,
                SerializerFeature.WriteMapNullValue,
                SerializerFeature.WriteDateUseDateFormat,
                SerializerFeature.BrowserCompatible,
                SerializerFeature.DisableCircularReferenceDetect);
        // 解决long型JS精度丢失问题
        SerializeConfig serializeConfig = SerializeConfig.globalInstance;
        serializeConfig.put(Long.class, ToStringSerializer.instance);
        serializeConfig.put(Long.TYPE, ToStringSerializer.instance);
        config.setSerializeConfig(serializeConfig);

        // 添加 FastJsonHttpMessageConverter
        FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new
                FastJsonHttpMessageConverter();
        fastJsonHttpMessageConverter.setFastJsonConfig(config);
        List fastMediaTypes = new ArrayList<>();
        fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
        fastJsonHttpMessageConverter.setSupportedMediaTypes(fastMediaTypes);
        converters.add(fastJsonHttpMessageConverter);
    }
}

写configureMessageConverters方法，添加自定义消息转换器。
