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

#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
