键空间

键空间（Keyspaces）定义了用于创建 Redis 哈希实际键的前缀。默认情况下，该前缀被设置为 getClass().getName()。您可以通过在聚合根级别上添加 @RedisHash 注解，或通过编程方式进行配置来更改此默认值。然而，使用注解指定的键空间将优先于任何其他配置。spring-doc.cadn.net.cn

以下示例展示了如何使用 @EnableRedisRepositories 注解设置 keyspace 配置：spring-doc.cadn.net.cn

示例 1. 通过 @EnableRedisRepositories 设置 Keyspace

@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"));
    }
  }
}

以下示例展示了如何以编程方式设置 keyspace：spring-doc.cadn.net.cn

示例 2. 以编程方式设置 Keyspace

@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"));
    }
  }
}
