当前使用版本(必填,否则不予处理)
3.3.1
该问题是如何引起的？(确定最新版也有问题再提!!!)
@TableField(typeHandler = JacksonTypeHandler.class)
private List<LocalDate> startDate;
重现步骤(如果有就写完整)
发现转换的时候，默认是转成ArrayList
报错信息
类型转换异常 `org.springframework.http.converter.HttpMessageNotWritableException: Could not write JSON: java.lang.String cannot be cast to java.time.LocalDate; nested exception is com.fasterxml.jackson.databind.JsonMappingException: java.lang.String cannot be cast to java.time.LocalDate
Caused by: com.fasterxml.jackson.databind.JsonMappingException: java.lang.String cannot be cast to java.time.LocalDate
保存进数据库的json 也是没有格式化之后的日期格式

手动配置jackson的序列化，设置自定义的ObjectMapper
