some examples for SpecificationArgumentResolver

This is a simple Spring Boot project which presents Specification Argument Resolver library.

It is an executable jar with embedded H2 db, so just build it with Maven and explore the API. You will find some samples below:

1. Get all customers:

   curl http://localhost:8080/customers

2. Delete a customer

   curl -X DELETE http://localhost:8080/customers/3

   it will perform a soft delete, which you can verify by getting all customers again -- the deleted customer will be still there, but with deleted = true flag. As you will see in subsequent points, specification-based query methods will filter it out.

3. Filter customers (include only not deleted ones) by first name and gender (optionally):

   curl http://localhost:8080/customers?firstName=ar curl 'http://localhost:8080/customers?firstName=ar&gender=MALE'

4. Filter by name (either first or last, case insensitive) with paging:

   curl 'http://localhost:8080/customers?name=l&page=0&size=2&sort=id'
