Hands-on using CouchbaseTemplate

Lets have a look on some CRUD operations using CommandLineRunner.

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

import com.tutorialspoint.couchbase.repository.CustomerRepository;
@SpringBootApplication
public class SpringDataCouchbaseApplication {
   private static final String DESIGN_DOC = "customer";
   @Autowired
   private CouchbaseTemplate template;
   public static void main(String[] args) {
      SpringApplication.run(SpringDataCouchbaseApplication.class, args);
   }
   @Bean
   CommandLineRunner commandLineRunner(CustomerRepository customerRepository) {
      return new CommandLineRunner() {
         @Override
         public void run(String... args) throws Exception {
            // Creating some documents
            template.insert(new Customer(105l, "John", "john@yahoo.com", 12000d));
            template.insert(new Customer(106l, "Franklin", "franklin@yahoo.com", 32000d));
            template.insert(new Customer(103l, "Simon", "simon@yahoo.com", 34000d));
            template.insert(new Customer(107l, "Cark", "clark@yahoo.com", 54000d));
            // Fetching documents
            System.out.println(template.findByView(ViewQuery.from(DESIGN_DOC, "all"), Customer.class));
            System.out.println(template.findByView(ViewQuery.from(DESIGN_DOC, "byEmail"), Customer.class));
            // Update document
            Customer customer = template.findById("103", Customer.class);
            customer.setSalary(55000d);
            customer.setName("Simon Ford");
            template.save(customer);
            // Deleting Document
            Customer customer7 = template.findById("107", Customer.class);
            template.remove(customer7);
         }
      };
   }
}
