ehcacheプロジェクトに(v2.6.0)を追加しようとしてHibernate 4.1.5.SP1いますが、構成に問題があります。具体的には、構成をビルドしようとするとjava.lang.NoClassDefFoundError:org/hibernate/cache/EntityRegionエラーが発生しますHibernate

    <property name="hibernate.cache.use_second_level_cache">true</property>
<property name="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</property>

これが私のMavenの依存関係です...

    <hibernate.version>4.1.5.SP1</hibernate.version>
    <hibernate.validator.version>4.3.0.Final</hibernate.validator.version>
    <ehcacheVersion>2.6.0</ehcacheVersion>
    ...
    <!-- Hibernate dependencies -->
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-validator</artifactId>
        <version>${hibernate.validator.version}</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>

        <artifactId>ehcache-core</artifactId>
        <version>${ehcacheVersion}</version>
    </dependency>

設定に使用するJavaコードは次のとおりです...

    Configuration config = new Configuration()
        .setProperty("hibernate.dialect", "org.hibernate.dialect.HSQLDialect")
        .setProperty("hibernate.connection.driver_class", "org.hsqldb.jdbcDriver")
        .setProperty("hibernate.connection.url", "jdbc:hsqldb:mem:myprojectTestDb")
        .setProperty("hibernate.connection.username", "sa")
        .setProperty("hibernate.connection.password", "")
        .setProperty("hibernate.connection.pool_size", "1")
        .setProperty("hibernate.connection.autocommit", "true")
        .setProperty("hibernate.cache.provider_class", "org.hibernate.cache.HashtableCacheProvider")
        .setProperty("hibernate.hbm2ddl.auto", "create-drop")
        .setProperty("hibernate.show_sql", "true")
        .setProperty("hibernate.current_session_context_class", "thread")
        .setProperty("hibernate.cache.use_second_level_cache", "true")
        .setProperty("hibernate.cache.region.factory_class", "net.sf.ehcache.hibernate.EhCacheRegionFactory")
        .addAnnotatedClass(Organization.class)
        .addAnnotatedClass(State.class) 
        .addAnnotatedClass(Country.class)
        .addAnnotatedClass(Domain.class)
        .addAnnotatedClass(Community.class);
    final ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(config.getProperties()).buildServiceRegistry();
    sessionFactory = config.buildSessionFactory(serviceRegistry);

ここに恐ろしいエラーがあります。不足している構成は何ですか?

ehcache-core ファイルは基本的に Hibernate 3.x 用です。Hibernate 4.x には、ehcache の独自の実装が付属しています。hibernate 4.x では、ehcache を明示的に使用する必要はありません。これがあなたの問題に対する最良の答えです。

依存関係を確認しました。Maven は、hibernate-ehcache パッケージがロードされると、常に ehcache-code をロードします。

依存関係ツリー:

+--- org.hibernate:hibernate-ehcache:4.3.0.Final
|    +--- org.jboss.logging:jboss-logging:3.1.3.GA
|    +--- org.jboss.logging:jboss-logging-annotations:1.2.0.Beta1
|    +--- org.hibernate:hibernate-core:4.3.0.Final (*)
|    \--- net.sf.ehcache:ehcache-core:2.4.3
|         \--- org.slf4j:slf4j-api:1.6.1 -> 1.6.6

持続性構成を確認してください。パッケージ名が「net.sf」で始まるクラスを含めないでください。

たとえば、コード内の次の文字列を置き換える必要があります。

.setProperty("hibernate.cache.region.factory_class", "net.sf.ehcache.hibernate.EhCacheRegionFactory")

次の文字列で:

.setProperty("hibernate.cache.region.factory_class", "org.hibernate.cache.ehcache.EhCacheRegionFactory")

Configuration.setProperty("hibernate.cache.region.factory_class", 
                     "net.sf.ehcache.hibernate.EhCacheRegionFactory")

Hibernate 4 の場合は、

org.hibernate.cache.ehcache.EhCacheRegionFactory instead of net.sf.ehcache.hibernate.EhCacheRegionFactory
