thymeleaf +spring date converting

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')}
