属性文件中的persistence.xml属性值

Question

I have below configuration for 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"/>

I also have persistence.xml file, now I want to add hibernate-search feature to my application, so I have added below properties in my persistence.xml file ..

<property name="hibernate.search.default.directory_provider" value="filesystem" />
<property name="hibernate.search.default.indexBase" value="/var/lucene/indexes" />

Here I want to externalize indexBase property value to properties file, something like this.

<property name="hibernate.search.default.indexBase" value="${index.location}" />

Can any please suggest how I can achieve this ?

I am using Spring version : 4.

Thanks.

I have added below code to my application-context.xml

Commented this

<jee:jndi-lookup id="entityManagerFactory"
                         expected-type="javax.persistence.EntityManagerFactory"
                         jndi-name="java:comp/env/persistence/appPersistenceUnit"/>

and added below bean configuration ..

<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>

But after server restart it give below exception.. but if i keep same property in persistence.xml it works fine ..

Exception: Error creating bean with name 'entityManagerFactory' defined in URL [vfs:/D:/App/Projects/Projects/wildfly/bin/content/app.war/WEB-INF/classes/META-INF/spring/appContext-web.xml]: Invocation of init method failed; nested exception is org.hibernate.service.spi.ServiceException: Unabl

Also, i wanted to check what is the use of in LocalContainerEntityManagerFactoryBean ?

Thanks.

Sorry, I didn't provide full information, in my existing persistence.xml file was already set to true, and it was working fine.

But in next requirement I had to implement search feature, so I used hibernate-search. And I have added and in persistence.xml, after that it's working fine. It created index when entity is checked in, also updates index when entity is updated..

As I have to deploy this code on different environment, i have to specify different location for each environment. For all environments i have different properties files. So i want to do same for this as well.. but after adding implementation as you suggested, still its not working ..

let me know if I can help you with any other information to find out solution ...

Below is my persistence.xml file ..

Let me know if you want me to add any other details . .

Since the persistence.xml lies outside the spring it isn't possible to inject properties via spring property placeholder.

The inherited method setJpaProperties of Springs' LocalContainerEntityManagerFactoryBean will solve the purpose you are looking forward too.

Sample spring bean configuration would look something like below -

<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>

Note that this will still read the configuration from persistence.xml with additional facilities. ( eg customized location for persistence.xml instead of default META-INF )
