III. Practice

1. Project Structure

1.1 Spring Boot Server

spring-boot-angular-6-spring-rest-api-data-cassandra-spring-server-structure
  • Customer class corresponds to entity and table customer.

  • CustomerRepository is an interface extends CassandraRepository, will be autowired in CustomerController for implementing repository methods and custom finder methods.

  • CustomerController is a REST Controller which has request mapping methods for RESTful requests such as: getAllCustomers, postCustomer, deleteCustomer, deleteAllCustomers, findByAge, updateCustomer.

  • Configuration for Spring Datasource and Spring JPA properties in application.properties

  • Dependencies for Spring Boot and Cassandra in pom.xml

    1.2 Angular 6 Client

    spring-boot-angular-6-spring-rest-api-data-cassandra-angular-client-structure In this example, we focus on:
  • 4 components: customers-list, customer-details, create-customer, search-customer.

  • 3 modules: FormsModule, HttpClientModule, AppRoutingModule.

  • customer.ts: class Customer (id, firstName, lastName)

  • customer.service.ts: Service for Http Client methods

    2. How to do

    2.0 Set up Cassandra

    Open Cassandra CQL Shell:
  • Create Cassandra keyspace with name javasampleapproach:

    
    create keyspace javasampleapproach with replication={'class':'SimpleStrategy', 'replication_factor':1};
    
  • Create customer table for javasampleapproach keyspace:

    
    use javasampleapproach;
    
    

CREATE TABLE customer( id timeuuid PRIMARY KEY, name text, age int, active boolean );
