弹簧 – 定制Cassandra转换器

我开始寻找一个很好的解决方案,如何使用Spring CassandraOperations很好地持久化实体.问题开始是因为我的实体中的某些字段不支持cassandra,例如joda DateTime.

解决方法是在java.util.Date类型的同一实体中使用其他字段而不是joda DateTime,使用@Transient标记不需要的字段.但这不干净,所以我开始寻找自动自定义转换.

目前spring-data-cassandra参考文献没有提供如何注册自定义转换器的信息. http://docs.spring.io/spring-data/cassandra/docs/current/reference/html/#cassandra.custom-converters

是否可以在CassandraSessionFactoryBean中注册自定义转换器(如此处为Spring Data Cassandra LocalDateTime Conversion)？

这是我的代码

@Value("${cassandra.contactpoints}")

@Value("${cassandra.port}")

    CassandraClusterFactoryBean cluster = new CassandraClusterFactoryBean();
    cluster.setContactPoints(cassandraContactPoint);
    cluster.setPort(cassandraPort);

    return cluster;

    session.setCluster(cluster().getObject());
    session.setKeyspaceName(cassandraKeySpace);
    session.setConverter(converter());
    session.setSchemaAction(SchemaAction.NONE);

    return session;
}

    return new CassandraTemplate(session().getObject());

    return bean.getObject();
}
