网上杂七杂八的说法不一，大多数都是抄来抄去，没有实践，近期在项目频繁遇到boot+jackson处理日期的问题，故开此贴。
首先是pom

然后是yml文件
（当然yml这东西很多人不喜欢，我也写了个properties版本的）

spring:
jackson:
#参数意义：
#jsoninclude.include.always 默认
#jsoninclude.include.non_default 属性为默认值不序列化
#jsoninclude.include.non_empty 属性为 空（””） 或者为 null 都不序列化
#jsoninclude.include.non_null 属性为null 不序列化
default-property-inclusion: always
time-zone: gmt+8
date-format: yyyy-mm-dd hh:mm:ss
|
上面配置对应的properties文件版本：
|
1

|
#jackson相关配置
spring.jackson.date-format = yyyy-mm-dd hh:mm:ss
#时区必须要设置
spring.jackson.time-zone= gmt+8
#always的意思是即时属性为null，仍然也会输出这个key
spring.jackson.default-property-inclusion=always

然后来定义一个controller和java bean

system.out.println(model.getintproperties());
system.out.println(sdf.format(model.getdateproperties()));

测试：
试一下，首先是日期序列化， 请求一下试试
然后是反序列化，也请求一个试试：
