How To Implement Soft Deletes Via SoftDeleteRepository In Spring Boot Application

Note: Spring Data built-in support for soft deletes is discussed in DATAJPA-307.

Description: This application is an example of implementing soft deletes in Spring Data style via a repository named, SoftDeleteRepository.

Key points:

• define an abstract class, BaseEntity, annotated with @MappedSuperclass
• in BaseEntity define a flag-field named deleted (default this field to false or in other words, not deleted)
• every entity that wants to take advantage of soft deletes should extend the BaseEntity classs
• write a @NoRepositoryBean named SoftDeleteRepository and extend JpaRepository
• override and implement the needed methods that provide the logic for soft deletes (check out the source code)
• repositories of entities should extend SoftDeleteRepository

Output example:
