Angular 7 + Spring Boot and Cloud Microservices(Inc. Docker)

Prepare our server-side infrastructure by setting up MySQL service to run in the background, configure the database workbench with root credentials, and adopt Java 8 for the project.

Leverage Hibernate as a Java object-relational mapping tool to map database tables to Java classes using annotations. It defines relationships and uses eager or lazy fetch types to optimize loading.

Explore JPA repositories in Spring Boot, leveraging auto configuration to perform CRUD operations with built-in methods like findById, save, and findAll, and create custom queries via method names or @Query.

Examine spring security authorization architecture with interceptors and access rules (permit all, deny all, authenticated, fully authenticated), and an access decision manager using voters and three strategies (affirmative, consensus, unanimous).

Configure application properties for your service by setting broker registration, enabling local servers, and ensuring local search connectivity so other services can connect in the local environment.

Explore discoverable services and instances with a local discovery service, create methods to fetch service ports and list user service instances, and redeploy microservices for testing.

Install Cassandra for the look service, verify that Cassandra is running. Start it if needed, and ensure the proper directory setup.

Create a new Spring Boot microservice project with Java, add Web, JPA for Cassandra, REST repositories, Cassandra, Eureka discovery, and Lombok, then import into IntelliJ or Eclipse ready for development.

Create a log repository interface that extends a crud repository for cassandra in spring. Use two generic parameters for the model and its id to enable basic crud operations.

Develop a Spring Boot microservices course service with MVC structure, a model-repository-controller flow, and Hibernate ORM. Configure database migrations, use Lombok, and expose API calls while integrating with other services.

select and configure a spring initializr microservice project, pick boot version 2.1.6, set group name and artifact name, and add rest api, persistence api, database migration, and service discovery dependencies.

Configure application properties by setting the app name, port, and database credentials, and establish Liquibase change logs and resources for migrations across services and databases.

Create a crud template with an abstract generic entity manager and a generic repository interface, using persistence contexts and the entity manager to perform save, find, and update operations.

Create a course repository using hql, with interface and implementation, marked transactional; write queries to filter courses by free text and to support a second query.

Enable the Eureka client and configure service discovery so microservices communicate by application name, register and list discovery service instances and ports.

Configure application properties for a Spring Boot microservices app, define api routes for user, pet, and course log services, and enable a proxy with Eureka and load balancing.

Define allowed origins for cross-origin resource sharing using a dedicated configuration class, override the CORS mappings, and enable proxy and CORS in the main class, with gateway service routing.

Build a client-side user interface for microservices, enabling login and registration, course listing with enrollment, and details for courses and profiles by consuming user and course services.

Implement user registration by calling the authentication service's register method and sending a rest api request to the user service, then navigate to login page via router and register controller.
