Spring Data HANA

The primary goal of the Spring Data project is to make it easier to build Spring-powered applications that use new data access technologies such as non-relational databases, map-reduce frameworks, and cloud based data services.

Artifacts

Maven

<dependency>
  <groupId>com.github.vogel612</groupId>
  <artifactId>spring-data-hanadb</artifactId>
  <version>1.5</version>
</dependency>

Usage (Spring Boot)

• Following properties can be used in your application.yml:

  spring:
    hana:
      url: http://localhost/
      authorization-header: basic authenticationToken==
      data-endpoint: SensorData
      stats-endpoint: SensorStats

  When your connection is based on HTTPS it may be necessary to specify a trust-store under hana like so:

      trust-store:
        location: /path/to/java/keystore/file
        password: securepassword

  The information given here will be used to set the system properties javax.net.ssl.trustStore and javax.net.ssl.trustStorePassword, which in turn govern how SSL certificates are validated.

• Create HanaDBConnectionFactory and HanaDBTemplate beans:

  @Configuration
  @EnableConfigurationProperties(HanaDBProperties.class)
  public class HanaDBConfiguration {
      @Bean
      public HanaDBTemplate<Point> template(final HanaDBProperties properties) {
          /*
           * You can specify a custom PointConverter implementation as the second parameter, 
           * if you want to use your own Measurement container  
           */
          return new DefaultHanaDBTemplate(properties);
      }
  }

• Use HanaDBTemplate to interact with the HanaDB database:

  @Autowired
  private HanaDBTemplate<Point> hanaDBTemplate;
  
  final Point p = Point.timeseries("disk")
    .time(System.currentTimeMillis())
    .value(12.25)
    .build();
  hanaDBTemplate.write(p);

Building

Spring Data HanaDB uses Maven as its build system.

mvn clean install
