This REST-Api demo application created in order to learn and understand the mechanism of managing Authentication with usage JWT and Authorization implementing PermissionEvaluator. Most of examples in net use regular Java Collections to store data entities. It causes inability to write reliable tests. This certain example uses JPA module with Hibernate for data persisting in H2 Database.

Imagine the organization which has several warehouses of different kind: CC, XD, TXD. Each warehouse has two types of trucks within it: TTT - for inbound and TPA - for outbound. Each truck has Manifest entities inside which represent a cargo loaded into the trucks. This organization has several kinds of users with different authorities for each kind of warehouses. Also these users has certain accesses for particular warehouses to process different CRUD actions. That's why PermissionEvaluator was used. All these entities: Warehouse, TPA, TTT, Manifest, User are being stored in H2. Only relations WarehousePermission are stored in WarehousePermissionRepo with usage of the ArrayList. All relation between objects initiated in DbInit class.
