Keyspaces

密钥空间定义了用于创建 Redis 哈希实际密钥的前缀。默认情况下，前缀设置为 getClass().getName()。可以通过在聚合根级别设置 @RedisHash 或通过设置程序化配置来更改此默认设置。但是，带注释的密钥空间优先于任何其他配置。

以下示例演示如何使用 @EnableRedisRepositories 注释设置密钥空间配置：

Example 1. Keyspace Setup via @EnableRedisRepositories

@Configuration
@EnableRedisRepositories(keyspaceConfiguration = MyKeyspaceConfiguration.class)
public class ApplicationConfig {

  //... RedisConnectionFactory and RedisTemplate Bean definitions omitted

  public static class MyKeyspaceConfiguration extends KeyspaceConfiguration {

    @Override
    protected Iterable<KeyspaceSettings> initialConfiguration() {
      return Collections.singleton(new KeyspaceSettings(Person.class, "people"));
    }
  }
}

以下示例演示如何通过编程设置密钥空间：

Example 2. Programmatic Keyspace setup

@Configuration
@EnableRedisRepositories
public class ApplicationConfig {

  //... RedisConnectionFactory and RedisTemplate Bean definitions omitted

  @Bean
  public RedisMappingContext keyValueMappingContext() {
    return new RedisMappingContext(
      new MappingConfiguration(new IndexConfiguration(), new MyKeyspaceConfiguration()));
  }

  public static class MyKeyspaceConfiguration extends KeyspaceConfiguration {

    @Override
    protected Iterable<KeyspaceSettings> initialConfiguration() {
      return Collections.singleton(new KeyspaceSettings(Person.class, "people"));
    }
  }
}
