How to solve the problem of springboot configuring date field to return timestamp

I encountered a problem. After springboot was upgraded to 2.0, the date found from the database was received using Date, and finally returned directly to the front end. It can be displayed normally as yyyy-MM-dd HH:mm:ss in Google Chrome. Format. However, the date displayed in the IE browser is "garbled" because the springboot1.x version returns a timestamp in the Date field by default, and Google and IE will automatically convert the timestamp into yyyy-MM-dd HH:mm: ss; after springboot2.0, spring will automatically convert the Date field into a UTC string (without configuration), so the date needs to be converted into a timestamp or yyyy-MM-dd HH:mm:ss. Add the following configuration to spring. I chose the return timestamp configuration and successfully solved the problem.

Configuration returns timestamp

spring
jackson:
serialization:
write-dates-as-timestamps:true

Global configuration returns string

spring:
    jackson:
        date-format: yyyy-MM-dd HH:mm:ss
        time-zone: GMT+8

With the second configuration, there is no need to configure Add the @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone="GMT 8") annotation to the date attribute of each entity class

# 指定执行环境
spring:
  profiles:
    # active: @env@
    active: dev
  jackson:
    serialization:
      WRITE_DATES_AS_TIMESTAMPS: true
