我有以下配置为entityManger
<jee:jndi-lookup id="dataSource" expected-type="javax.sql.DataSource"
jndi-name="java:jboss/datasources/AppDS"/>
<jee:jndi-lookup id="entityManagerFactory"
expected-type="javax.persistence.EntityManagerFactory"
jndi-name="java:comp/env/persistence/appPersistenceUnit"/>
我也有persistence.xml文件，现在我想在我的应用程序中添加hibernate-search功能，所以我在persistence.xml文件中添加了以下属性..
<property name="hibernate.search.default.directory_provider" value="filesystem" />
<property name="hibernate.search.default.indexBase" value="/var/lucene/indexes" />
这里我想将indexBase属性值外部化为属性文件，类似这样。
<property name="hibernate.search.default.indexBase" value="${index.location}" />
请问我可以建议如何实现这个目标吗？
我使用的是Spring版本：4。
感谢。
更新 - 2 我已将下面的代码添加到我的application-context.xml
评论
<jee:jndi-lookup id="entityManagerFactory"
expected-type="javax.persistence.EntityManagerFactory"
jndi-name="java:comp/env/persistence/appPersistenceUnit"/>
并在bean配置下添加..
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.search.default.indexBase">/var/lucene/indexes</prop>
</props>
</property>
</bean>
但是在服务器重启之后它给出了以下异常..但是如果我在persistence.xml中保留相同的属性它可以正常工作..

另外，我想检查LocalContainerEntityManagerFactoryBean中 configLocation 的用途是什么？
感谢。
更新 - 3
抱歉，我在现有的persistence.xml文件中没有提供完整信息 hibernate.cache.use_second_level_cache 已设置为true，并且工作正常。
但是在下一个要求中我必须实现搜索功能，所以我使用了hibernate-search。我在persistence.xml中添加了 hibernate.search.default.indexBase 和 hibernate.search.default.directory_provider ，之后它运行正常。它在签入实体时创建索引，在实体更新时也更新索引。
由于我必须在不同的环境中部署此代码，因此我必须为每个环境指定不同的位置。对于所有环境，我都有不同的属性文件。所以我想为这个 hibernate.search.default.indexBase 做同样的事情..但是按照你的建议添加实现后，仍然无法正常工作..
如果我能帮助您找到解决方案的任何其他信息，请告诉我......

答案 0 :(得分：0)
由于persistence.xml位于弹簧之外，因此无法通过spring属性占位符注入属性。
Springs＆＃39;的继承方法setJpaProperties LocalContainerEntityManagerFactoryBean也将解决您期待的目标。
示例spring bean配置如下所示 -
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.hbm2ddl.auto">create-drop</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.search.default.indexBase">${index.location}</prop>
</props>
</property>
请注意，这仍然会从persistence.xml读取配置以及其他功能。 （例如persistence.xml的自定义位置，而非默认META-INF ）
