spring data cassandra＆elasticsearch設定の使い方

Question

私はSpring Data CassandraとSpring Bootを両方とも使用しようとしています。& Spring Data ElasticSearchをSpring起動アプリケーションで使用しようとしています。 私は既にCassandraリポジトリ& ElasticSearchリポジトリを別のパッケージに入れました。

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

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

は、私が実行しようとしたとき、私は次の例外を得た::

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].

Answer 1

私も、私が作成しCassandraConverter（）オブジェクトにこれを使用してCassandraMappingContextでコンストラクタを使用していた、同じ問題に直面しましたそれが問題を作り出していました。

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. 
    } 

この問題を解決するには、私が上記の置き換え： - コードの

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

、残りの部分はCassandraSessionFactoryBean（このコンバータを設定する同じまま）

の場合あなたの問題は解決されていません、スニペットを提供してください、私は正しい構成を提供します。
