Cannot convert '0000-00-00 00:00:00' to TIMESTAMP
Solution 1
I'm going to take a wild guess here that you're using MySQL :-) It uses "zero dates" as special placeholder - unfortunatelly, JDBC can not handle them by default.
The solution is to specify "zeroDateTimeBehavior=convertToNull" as parameter to your MySQL connection (either in datasource URL or as an additional property), e.g.:
jdbc:mysql://localhost/myDatabase?zeroDateTimeBehavior=convertToNull
This will cause all such values to be retrieved as NULLs.
Solution 2
I don't understand the point in your code, where you format then parse again a date. This seems like an identical operation. Maybe you could elaborate?
If you want to give a default value to a date, you could do :
/** Jan 1, 1970 ; first moment in time in Java */
private static final Date NO_DATE = new Date(0L);
private Date date;
public void setDate(final Date date) {
if (date == null) {
this.date = NO_DATE;
} else {
this.date = date;
}
}
Note : the annotation are optionnal, here I didn't add them.
In this code, you could substitute what you want to the condition, and to the default value.
You could also add a similar setter, that would take a String argument, and check for your special "00000..." value. This would allow for setting the field either with a Date, or with a String.

the field definition
/** Date. */ @Column(columnDefinition = "datetime") private Date date;
setter
public void setDate(final Date date) { DateFormat dfmt = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); try { this.date = dfmt.parse(dfmt.format(date)); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } }
Does anyone have idea how to convert "zero date" into proper value ? Because i have error:
Cannot convert value '0000-00-00 00:00:00' from column 13 to TIMESTAMP
And even if i set "default" field and setter like this:
/** Date. */ @Column private Date date; public void setDate(final Date date) { this.date = date; }
I'll still have the same problem....
