• SpringBoot之自定义Jackson反序列化日期类型转换配置类
• 1. SpringBoot版本
• 2. Jackson反序列化���期类型配置类
  1. 全局自定义Jackson反序列化日期类型时,类型转换配置类,仅用于@RequestBody注解接收参数时使用
  2. 注意：如果开启了此配置类,yml中配置的日期返回格式spring.jackson.date-format配置不起作用

  1. SpringBoot版本

           org.springframework.boot        spring-boot-starter-parent        2.3.5.RELEASE    

  2. Jackson反序列化日期类型配置类
