多租户的Spring数据Redis

Question

@RedisHash(value = “products")
public class Product {

    @Id
    @Indexed
    private String id;
    private String description;
    private BigDecimal price;
    private String imageUrl;

   //Getter and Setter

}

@Repository
public interface ProductRepository extends CrudRepository<Product,String> {
}

@Configuration
@EnableRedisRepositories(enableKeyspaceEvents = RedisKeyValueAdapter.EnableKeyspaceEvents.ON_STARTUP)
public class RedisConfig {

    @Bean
    JedisConnectionFactory jedisConnectionFactory() {
        JedisConnectionFactory jedisConFactory = new JedisConnectionFactory();
        jedisConFactory.setHostName("localhost");
        jedisConFactory.setPort(6379);
        return jedisConFactory;
    }
}

我认为为每个租户创建一个Redis实例是一个很好的解决方案。

我有一个包含租户id和Redisendpoint的映射，这是专用于这个租户的。

地图数据如下所示：

(Key : tenantId1, value: host1:port1) 
(Key : tenantId2, value: host2:port2)
(Key : tenantId3, value: host3:port3)

为了实现多租户结构，您可以按照以下方式进行：

  @Bean(name = "JedisConnectionFactor" )
  public Map<String, JedisConnectionFactory> JedisConnectionFactor(){
    Map<String, DataSource> factories = new HashMap<>();
    //for (JedisProperties properties :  // better to import jedis config from for each single tenant
      //multiTenantJedisProperties.getListOfProperties()) { 

      JedisConnectionFactory jedisConFactory = new JedisConnectionFactory();
      jedisConFactory.setHostName("localhost");
      jedisConFactory.setPort(6379);
      result.put(jeditProperties.getTenantId(), jedisConFactory)
     // iterate ....
      JedisConnectionFactory jedisConFactory = new JedisConnectionFactory();
      jedisConFactory.setHostName("localhost");
      jedisConFactory.setPort(6379);
      result.put(jeditProperties.getTenantId(), jedisConFactory);
     // n times

    }
    return factories;
  }

您可以使用autowire工厂地图

@Autowired
   private Map<String, JedisConnectionFactory> JedisConnectionFactories;

   @Autowire
   protected DataSource selectJedisConnectionFactory(String tenantId) {
     return this.JedisConnectionFactories.get(tenantId);
   }

希望这能有所帮助！
