如何使用彈簧數據cassandra和elasticsearch配置

我試圖在Spring Boot應用程序中使用Spring Data Cassandra & Spring Data ElasticSearch。我已經將Cassandra Repository & ElasticSearch存儲庫放在不同的包中。如何使用彈簧數據cassandra和elasticsearch配置

@EnableElasticsearchRepositories(basePackages = "com.my.app.es.repository") 
public class ElasticsearchConfig { 
    ... 
} 

@EnableCassandraRepositories(basePackages = { "com.my.app.cassandra.repository" }) 
public class CassandraConfig extends AbstractCassandraConfiguration { 
    ... 
}

當我試圖運行，我得到了以下異常：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'converter' defined in class path resource [com/my/app/config/CassandraConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.cassandra.convert.CassandraConverter]: Factory method 'converter' threw exception; nested exception is java.lang.IllegalStateException: @Bean method CassandraConfig.mappingContext called as a bean reference for type [org.springframework.data.cassandra.mapping.CassandraMappingContext] but overridden by non-compatible bean instance of type [org.springframework.data.elasticsearch.core.mapping.SimpleElasticsearchMappingContext].

我也面臨着同樣的問題，我就是用這個來創建CassandraConverter（）對象，並使用與CassandraMappingContext構造這是造成這個問題。

問題： -

@Bean 
    public CassandraMappingContext mappingContext() { 
     return new BasicCassandraMappingContext(); 
    } 

    @Bean 
    public CassandraConverter converter() { 
     return new MappingCassandraConverter(mappingContext()); //Remove this and call MappingCassandraConverter() with passing any arguement. 
    }

爲了解決這個問題我與上述取代： -

@Bean 
    public CassandraConverter converter() throws ClassNotFoundException { 
     return new MappingCassandraConverter(); 
    }

和休息一段代碼保持相同設定CassandraSessionFactoryBean）該轉換器（

如果你的問題沒有解決請提供片段，我會提供正確的配置。
