JdbcOperationsSessionRepositoryの型java.lang.Objectからbyte []への変換が可能なコンバーターが見つかりません

Question

spring xmlベースの構成でoracle DbにSpringセッションを格納しようとしています。 http://docs.spring.io/spring-session/docs/current/reference/html5/guides/httpsession-jdbc-xml.html

ジャーをWEb-INF/lib/で：スプリングDOCガイドで提案されているよう

Iは手動テーブル（SPRING_SESSIONとSPRING_SESSION_ATTRIBUTES）スキーマのoracle.sqlに設けられ、web.xmlおよびsession.xmlのエントリを提供を作成しました。

Answer 1

私はこの作業を得ましたorg.springframework.session.jdbc.config.annotation.web.http.JdbcHttpSessionConfigurationのものが正しく読み込まれないように見えるので、私自身のConverterを実装してください。

私は自分自身を作成し​​て保存するデータを得ましたByteaConversionServiceJdbcHttpSessionConfiguration。

まずプロパティで

<bean class="org.springframework.session.jdbc.config.annotation.web.http.JdbcHttpSessionConfiguration"> 
    <property name="springSessionConversionService"> 
     <bean class="com.mycompany.ByteaConversionService" /> 
    </property> 
</bean> 

をxml設定でBeanを作成し、これは私のために働いたcom.mycompany

public class ByteaConversionService extends GenericConversionService { 
    public ByteaConversionService() { 
     addConverter(Object.class, byte[].class, new SerializingConverter()); 
     addConverter(byte[].class, Object.class, new DeserializingConverter()); 
    } 
} 

パッケージ内のクラスを作成します。 （今、私は複数のセッションを動作させる方法に苦労しています）
