Hibernate Search and Spring

Welcome!

I have searched a lot (Google and this discussion board, https://www.hibernate.org/441.html), tried lots of old hibernate and spring versions, and still I cannot make it work correctly. Everything seems to work fine except reindexing on update relation entity. I think it might be an issue associated with executing FullTextIndexEventListener.

My example is the authors<->books application. I do the following in my index test case:

Code:

        AuthorDAO authorDAO = (AuthorDAO) ctx.getBean("authorDAOImpl");
        AuthorEntity a = new AuthorEntity();
        a.setFirstName("author");
        a.setLastName("author");
        authorDAO.saveAuthor(a);

        BookDAO bookDAO = (BookDAO) ctx.getBean("bookDAOImpl");
        BookEntity b = new BookEntity();
        b.setTitle("title");
        b.setPublicationDate(new Date());
        b.setContent("content");
        Set<AuthorEntity> authors = new HashSet<AuthorEntity>();
        authors.add(a);
        b.setAuthors(authors);
        bookDAO.saveBook(b);

// Everything ok here. Indexed data is correct.

        a.setFirstName("Changed"); // Changing value.
        authorDAO.saveAuthor(a); // Here the authors.firstName index property is not being reindexed

Library versions:
Hibernate 3.3.2.GA
Hibernate Search 3.1.1.GA
Hibernate Annotations 3.4.0.GA
Spring 2.5.6.SEC01

My code:
Spring configuration:

Code:

    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations" value="classpath:jdbc.properties"/>
    </bean>

    <bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource"
          init-method="createDataSource">
        <property name="driverClassName" value="${jdbc.driverClassName}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>

    <bean id="hibernateSessionFactory"
          class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="schemaUpdate" value="true"/>
        <property name="hibernateProperties">
            <value>
                hibernate.dialect = org.hibernate.dialect.DataDirectOracle9Dialect
                hibernate.hbm2ddl.auto = create
                hibernate.show_sql = true
                hibernate.format_sql = false
                hibernate.search.default.directory_provider = org.hibernate.search.store.FSDirectoryProvider
                hibernate.search.default.indexBase = C:\index\
            </value>
        </property>
        <property name="annotatedClasses">
            <list>
                <value>edu.lantoniak.hibernate.search.model.AuthorEntity</value>
                <value>edu.lantoniak.hibernate.search.model.BookEntity</value>
            </list>
        </property>
    </bean>

    <bean id="authorDAOImpl" class="edu.lantoniak.hibernate.search.dao.AuthorDAOImpl">
        <property name="sessionFactory" ref="hibernateSessionFactory"/>
    </bean>

    <bean id="bookDAOImpl" class="edu.lantoniak.hibernate.search.dao.BookDAOImpl">
        <property name="sessionFactory" ref="hibernateSessionFactory"/>
    </bean>

DAO implementation:

Code:

public class BookDAOImpl extends HibernateDaoSupport implements BookDAO {
    public void saveBook(BookEntity b) {
        getHibernateTemplate().saveOrUpdate(b);
    }
}

Mappings:

Code:

@Entity
@javax.persistence.SequenceGenerator(name="BOOKS_SEQ_GEN", sequenceName="BOOKS_SEQ")
@Table(name="BOOKS")
@Indexed
public class BookEntity {
...
    @ManyToMany(targetEntity=AuthorEntity.class)
    @JoinTable(name="AUTHORS_BOOKS", joinColumns=@JoinColumn(name="BOOKS_ID"), inverseJoinColumns=@JoinColumn(name="AUTHORS_ID"))
    @IndexedEmbedded(depth=1)
    public Set<AuthorEntity> getAuthors() {
        return authors;
    }
...
}

Code:

@Entity
@javax.persistence.SequenceGenerator(name="AUTHORS_SEQ_GEN", sequenceName="AUTHORS_SEQ")
@Table(name="AUTHORS")
@Indexed
public class AuthorEntity {
...
    @ManyToMany(mappedBy="authors", targetEntity=BookEntity.class)
    @ContainedIn
    public Set<BookEntity> getBooks() {
        return books;
    }
...
}

I have tried getHibernateTemplate().setExposeNativeSession(true); before savOrUpdate, and explicite registering eventListners but it did not help.
I will be very grateful for any help.

Regards,
Lukasz

Edit: I have tried also playing with:

Code:

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="hibernateSessionFactory"/>
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager"/>

    @Transactional(propagation=Propagation.REQUIRED)
    public void saveBook(BookEntity b) {
        getHibernateTemplate().saveOrUpdate(b);
    }

But still nothing happens.

BTW have you committed (or called flush(); flushToIndexes(); ) before doing your test on the index?
Changes are only visible after these boundaries.

Actually HibernateTemplate shall do it for me. I have changed the implementation of saveAuthor() method to one shown below, but still I do not see "Changed" first name.

Code:

public void saveAuthor(AuthorEntity a) {
        Session session = getSession();
        FullTextSession fullTextSession = Search.getFullTextSession(session);
        Transaction t = fullTextSession.beginTransaction();
        fullTextSession.saveOrUpdate(a);
        t.commit();
        fullTextSession.flush();
        fullTextSession.flushToIndexes();
}

In the database everything is ok. (I see "Changed" first names)

Edit:
I would say even more (the SessionFactory received from HibernateTemplate has event listeners present):

Code:

@Transactional(propagation=Propagation.REQUIRED)
    public void saveAuthor(AuthorEntity a) {
        getHibernateTemplate().saveOrUpdate(a);
        EventListeners e = ((SessionFactoryImpl)getHibernateTemplate().getSessionFactory()).getEventListeners();
        System.out.println(e.getPostCollectionRecreateEventListeners()[0].getClass().getName());
        System.out.println(e.getPostCollectionRemoveEventListeners()[0].getClass().getName());
        System.out.println(e.getPostCollectionUpdateEventListeners()[0].getClass().getName());
    }

Returns:

Code:

org.hibernate.search.event.FullTextIndexEventListener
org.hibernate.search.event.FullTextIndexEventListener
org.hibernate.search.event.FullTextIndexEventListener

Issue solved. I have been using to up-to-date author object. Sorry for making trouble, and thank you for your help.
