findAll Sort by Order

the Sort by(Order by(String property)) method defined in PagingAndSortingRepository interface and implemented in the SimpleJpaRepository class is used to retrieve all the records from the underlying database in the direction provided using Order class. Order class provides multiple ways to sort the records from the underlying database.

• Order(@Nullable Direction direction, String property)
• Order(@Nullable Direction direction, String property, NullHandling nullHandlingHint)
• Order by(String property)
• Order asc(String property)
• Order desc(String property)
• Order(@Nullable Direction direction, String property,
• boolean ignoreCase, NullHandling nullHandling)

OrderBy

The static OrderBy method defined in static Order class takes a single property and is used to provide the property on which order must be applied while retrieving records from the underlying database. OrderBy uses the default Ascending direction.
