thymeleaf +spring date converting - thymeleaf

Question

This is my data model. I want to use date from here.
I do this in my html:
<table th:if="${!commentsInTask.empty}">
<tbody>
<tr th:each="Comments : ${commentsInTask}">
<tr th:each="comment : ${Comments}">
<td th:text="${comment.user}">user ...</td>
<td th:text="${comment.createdAt}">date ...</td>
</tr>
</tr>
</tbody>
</table>
but it brings:
<table>
<tbody>
<td>JACK</td>
<td>1.476787930289E9</td>
</tr>
</tr>
</tbody>
</table>
This part is unix timedate:
1.476787930289E9
but in the picture at beginning i posted, you saw. Timme is not that.
This is in domain
public String getCreatedAtString() {
return createdAtString;
}
public TaskComment setCreatedAtString(String createdAtString) {
this.createdAtString = createdAtString;
return this;
}
private ZonedDateTime createdAt = ZonedDateTime.now();
Why cantt i see in date format which in picture at the beginning?

Answer 1

Use Thymeleaf formatting:
<td th:text="${#dates.format(comment.createdAt, 'dd-MM-yyyy HH:mm:ss')}">date</td>
You'll get an output in the following format: 18-Oct-2016 14:44:05.
#dates: methods for java.util.Date objects: formatting, component extraction, etc.
To convert your createdAt field to java.util.Date type use:
Date date = Date.from(java.time.ZonedDateTime.now().toInstant());
Or just use java.util.Date type:
private Date createdAt = new Date();
this will set cheatedAt to current date.
Also you can add thymeleaf-extras-java8time dependency to your project to work with your ZonedDateTime type.
This module adds a #temporals object similar to the #dates or #calendars ones in the Standard Dialect, allowing the formatting and creation of temporal objects from Thymeleaf templates:
Then you can use ZoneDateTime with the specified pattern:
${#temporals.format(temporal, 'dd/MM/yyyy HH:mm')}
