@RepositoryRestResource(path = "members")

if we want to expose a different resource name? instead of "/employees" (or default) to use "/members" (customized) so path will be http://localhost:8080/members

Pagination

• Default page size is 20
• Pages are zero index based
• To navigate page
  • http://localhost:8080/employees?page=0
  • http://localhost:8080/employees?page=1
• Properties
  • spring.data.rest.default-page-size=50
  • spring.data.rest.max-page-size=

To make default base path

• spring.data.rest.base-path=/magic-api

Here, http://localhost:8080/magic-api will be default base path

Sorting

In Employee,we have firstName, lastName and email

• http://localhost:8080/employees/?sort=lastName
