Spring Applications

Project: Order Service Security

The objective of this exercise is to secure the order service of the bookstore application using basic authentication and access control.

1. Add the starter spring-boot-starter-security and org.springframework.security:spring-security-test as Maven dependencies.
2. Add a password property to the customer entity and a corresponding column to the customer table of the database schema.
3. Implement a user details service that can load a fixed user with the role EMPLOYEE and customers with their email address as username, their passwords and the role CUSTOMER.
4. Implement a security configuration class that creates a security filter chain such that basic authentication is used and access to the REST endpoints is restricted as follows:

   Service	Function	Authentication required	Grant access to role
   			CUSTOMER	EMPLOYEE
   Customer	Register customer Find customer Search customers Update customer	no yes yes yes	yes no yes	yes yes yes
   Order	Place order Find order Search orders Cancel order	yes yes yes yes	yes yes yes yes	no yes yes yes

5. Use the AccessController component in the customer and order service to ensure that customers can only access their own data.
6. Test the security constraints using the Postman utility and run the OrderSecurityIT integration test.
