springboot全局日期格式化的两种方式

 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，对应yml里面的注释里面的类型 spring.jackson.default-property-inclusion=ALWAYS
