This article mainly introduces the Spring DATA JPA findAll how to carry out OrderBy, the article is very detailed, has a certain reference value, interested friends must read it!

FindAll in Spring DATA JPA for OrderBy

You need to define such a method in repository: findAllByOrderByUpdatedAtDesc ()

Public List findAllByOrderByUpdatedAtDesc ()

Important: (add an extra By in the middle)

FindAllByOrderByUpdatedAtDesc ()

The little 'By' does all the magic.

Spring Data JPA uses a small pit of orderby.

According to the JPA writing method that can be found on the Internet, I want to find all the data and arrange them in ascending order of rank. The code is as follows.

Public interface RsEventRepository extends CrudRepository {List findAllByOrderByRankAsc ();}

As a result, java reported an error, and then looked for problems in entity and repository.

Java.lang.IllegalStateException: Failed to load ApplicationContext

No property asc found for type int! Traversed path: RsEventEntity.rank.

Finally, it was found that a by should be added after ALL.

List findAllByOrderByRankAsc ()

In this way, I can make an inquiry according to my idea.
