@Column(name = "CREATED_DATE")

@DateTimeFormat(iso=ISO.DATE_TIME)

return this.createdDate;
}
@Column(name = "LAST_MODIFIED_DATE")

}
In Listing 21-24, the date-time format annotations are highlighted in bold. For the createdDate and
lastModifiedDate properties, the annotation is applied, and the type ISO.DATE_TIME format is used,
which corresponds to the format yyyy-MM-dd'T'hh:mm:ss.SSSZ (for example, 2012-01-
30T13:53:52.324+08:00). This is because for the create date and last modified date, we also want to know
the time in addition to the date. Note that Spring supports the formatting of JodaTime's DateTime type
out of the box.
Figure 21-20 shows the view page of a blog post entry in SpringBlog, and in the figure, you can see
the conversion and formatting in action.
