Installation

• Install this project to your local maven repository

  git clone https://github.com/vince-bickers/spring-data-jsondb.git

  mvn clean install
  

Usage

• Declare the dependency in your pom

    <dependency>
        <groupId>org.mambofish</groupId>
        <artifactId>spring-data-jsondb</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>
  

• Enable Spring Data/Spring Boot support for JsonDB, using @EnableJsonDBRepositories

  @SpringBootApplication
  @EnableJsonDBRepositories(basePackages = ".....")
  public class Application {
  
      @Value("${json.db.files.location}")
      private String dbFilesLocation;
  
      @Value("${json.db.scan.package}")
      private String dbScanPackage;
  
      @Bean
      public JsonDBTemplate jsonDBTemplate() {
          return new JsonDBTemplate(dbFilesLocation, dbScanPackage);
      }
  
      public static void main(String[] args) {
          SpringApplication.run(Application.class, args);
      }
  }
  

• JsonDB Person (note: this example uses Lombok)

  @Data
  @Document(collection = "people", schemaVersion = "1.0")
  @JsonInclude(JsonInclude.Include.NON_NULL)
  public class Person {
  
      private @Id String name;
      private List<Person> friends = new ArrayList<Person>();
  
  }
  

• Spring Data Repository

  public interface PersonRepository extends PagingAndSortingRepository<Person, String> {}
  

• Bootstrap some data...

  @Component
  public class Bootstrapper implements CommandLineRunner {
  
      private final PersonRepository repository;
  
      @Autowired
      public Bootstrapper(PersonRepository repository) {
          this.repository = repository;
      }
  
      @Override
      public void run(String... strings) throws Exception {
              
          Person john = new Person();
          Person mary = new Person();
          
          john.setName("john");
          mary.setName("mary");
          john.setFriends(Arrays.asList(mary));
          
          this.repository.save(john);
      }
  }
