Spring boot JPA with MySql DB - mapping Dates ends in having wrong day (1 day off)

Question

currently I am facing a strange issue with Spring JPA : Whenever I try to map a date as Date only, it saves the day I want to save minus 1 day. E.g. saving 1st of Feb --> I have 31st of Jan in my DB. As long as I am using DateTime, everything is ok. Example : MySQL time zone set to System System is on UTC + 1 in connection URL, serverTimeZone is set to UTC and useLegacyDatetimeCode = true

@Entity
public class ZoneEntity
{
    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    private Long id;

    @CreationTimestamp
    private LocalDateTime createDateTime;

    @CreationTimestamp
    private LocalDate createDate;

    @Temporal(value = TemporalType.TIMESTAMP)
    private Date temporalDate;

    private LocalDateTime localDateTime;

    private LocalDate localDate;

    @Column(columnDefinition = "DATE")
    private LocalDate localDateWithColumn;

    public ZoneEntity() {
        temporalDate = new Date();
        localDateTime = LocalDateTime.now();
        localDate = LocalDate.now();
        localDateWithColumn = LocalDate.now();
    }

I'll then save a new entity like this :

service.save(new ZoneEntity());

If I execute this today (24.02.2020), I'll end up with the following

createDateTime : 24.02.2020 15:20:00  --> Correct (UTC)

createDate : 23.02.2020 --> day - -1

temporalDate : 24.02.2020 15:20:00 --> Correct (UTC)

localDate : 23.02.2020 --> day - 1

localDateTime : 24.02.2020 15:20:00 --> Correct (UTC)

localDateWithColumn : 23.02.2020 --> day - 1

So however I save the date only, it ends with the wrong day. Does anybody have any idea why this happens ?

If I have a look in the hibernate logging, the issue seems to be on the MySQL side...

Hibernate: 
    insert 
    into
        zone_entity
        (create_date, create_date_time, local_date, local_date_time, local_date_with_column, temporal_date, id) 
    values
        (?, ?, ?, ?, ?, ?, ?)
2020-02-24 16:42:25.371 TRACE 19628 --- [nio-8080-exec-2] o.h.type.descriptor.sql.BasicBinder      : binding parameter [1] as [DATE] - [2020-02-24]

added : if I try to insert via MySQL workbench with the values below (as the parameters from Hibernate look like), everything is ok (left out the timestamp to make it a bit shorter).

insert 
    into
        zone_entity
        (create_date, create_date_time, local_date, local_date_time, local_date_with_column,id) 
    values
        ('2020-02-24', '2020-02-24T22:03:13.842324', '2020-02-24', '2020-02-24T22:03:13.842324', '2020-02-24',99);

added: I now changed time zone in DB URL to Europe/London --> everything works as it should. Changing to UTC or Europe/London --> both does not work !

spring.datasource.url = jdbc:mysql://localhost:3306/myDatabase?serverTimezone=Europe/Berlin&useLegacyDatetimeCode=false

Many thanks in advance !

Kind regards

Having you tried with the below parameter in spring yml?

spring:
  jpa:
    properties:
       hibernate.jdbc.time_zone: Europe/Berlin
