• Where is the pit ?
 
      serialize and Deserialization The time is right Date Inconsistent formatting of fields
 
      for example : take Java bean Serialized into Json string When The format is yyyy-MM-dd When parsing, the format is yyyy-MM-dd hh:mm:ss, Will throw parsing exception
 
      To put it bluntly, it is to convert a string into Date type , But the format doesn't match , Of course, the conversion will fail

  • How can we not be trapped ?
 
          Or both parties agree on the time format
          Or don't format the data , Direct use Date Value interaction It's a long Type value
