fastJson的配置时间序列化格式
fastJson的配置时间格式化，如果在config中配置的话，所有的bean都会统⼀格式，有的项⽬灵活格式。
1.JSONObject.DEFFAULT_DATE_FORMAT="yyyy-MM-dd";//设置⽇期格式
JSONString(resultMap, SerializerFeature.WriteMapNullValue,SerializerFeature.DisableCircularReferenceDetect, SerializerFeature.WriteDateUseDateFormat);
但是上⾯的解决⽅案⾯临⼀个问题，如果不满⾜上⾯的条件（多个date属性，⽽且需要按照不定的格式序列化这些⽇期属性），那么我们就需要另辟蹊径，使⽤fastjson的特性来完成：
@JSONField(format="yyyyMMdd")
private Date date;
@JSONField(format="yyyy-MM-dd HH:mm:ss")
private Date date1;
配置⽂件： 其中configureMessageConverters 配置了消息转换，fastJsonConfig.setDateFormat(“yyyy-MM-dd HH:mm:ss”)；统⼀样式。
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern="yyyy-MM-dd", timezone = "GMT+8")
和 jastJson冲突。
