fastjson就是自定义json格式，字体大小等等

@Overridepublic void configureMessageConverters(List
     
      > converters) {    super.configureMessageConverters(converters);    //定义一个convert转换消息的对象    FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();    //添加fastjson配置信息    FastJsonConfig fastJsonConfig = new FastJsonConfig();    fastJsonConfig.setSerializerFeatures(PrettyFormat);    //在convert中添加配置信息    fastConverter.setFastJsonConfig(fastJsonConfig);    //将fastConverter添加到converters中    converters.add(fastConverter);}
     

@JSONField(format = "yyyy-MM-dd HH:mm")private Date cretedTime;

实例2：//不在页面显示该json数据

@JSONField(serialize = false)private String remarsk;
