Caused by: com. fasterxml. jackson. databind. Exc.invalidformatexception: exception resolution

Abnormal information ：

Caused by: com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type `java.util.Date` from String "2022-05-26 15:36:45": not a valid representation (error: Failed to parse Date value '2022-05-26 15:36:45': Cannot parse date "2022-05-26 15:36:45": while it seems to fit format 'yyyy-MM-dd'T'HH:mm:ss.SSSX', parsing fails (leniency? null))

The reason for the error ：

• By default ,Jackson Use com.fasterxml.jackson.databind.util.StdDateFormat Class to format .
  The time format is ：yyyy-MM-dd’T’HH:mm:ss.SSSZ, by ISO-8601 data type .

• jackson The default date inverse sequence does not support yyyy-MM-dd HH:mm:ss This format , So deserialization failed

terms of settlement ：

• Solution 1 ： stay yml Configure the serialization format and time zone in the configuration

  spring:
    jackson:
      date-format: yyyy-MM-dd HH:mm:ss #  The default is StdDateFormat
      time-zone: GMT+8
  

• Solution 2 ： Use... On the entity class date parameter jackson annotation

  @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss",timezone = "GMT+8")
  private Date createTime;
  

• Solution three ： Use... On the entity class date parameter fastjson annotation

  @JSONField(format = “yyyy-MM-dd HH:mm:ss”)
  private Date createTime; 
  

• Solution 4 ： rewrite jackson Deserialization

  import com.fasterxml.jackson.core.JsonParser;
  import com.fasterxml.jackson.core.JsonProcessingException;
  import com.fasterxml.jackson.databind.DeserializationContext;
  import com.fasterxml.jackson.databind.JsonDeserializer;
   
  import java.io.IOException;
  import java.text.ParseException;
  import java.text.SimpleDateFormat;
  import java.util.Date;
   
   
  public class CustomJsonDateDeserializer extends JsonDeserializer<Date> {
        
   
      @Override
      public Date deserialize(JsonParser jp, DeserializationContext ctxt) throws IOException, JsonProcessingException {
        
          SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
          String date = jp.getText();
          try {
        
              return format.parse(date);
          } catch (ParseException e) {
        
              throw new RuntimeException(e);
          }
      }
  }
  

  @JsonDeserialize(using = CustomJsonDateDeserializer.class)
  private Date createTime;
