Using openEntityManagerInView still getting "failed to lazily initialize a collection of role"

Question

I am trying to return one of my entities to a JSP page but getting the following error "failed to lazily initialize a collection of role". I have added the openEntityManagerInView filter(assuming it would allow the entity manager to stay open in the view?) but still getting this error.

My application is configured using java config no xml.

Below is my dispatcher servelet. You can see i have added the openEntityManagerInView filter.

Any ideas why this is? I have checked similar questions on stackoverflow and have had no luck to the solutions provided.

public class DispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

@Override
public void onStartup(ServletContext servletContext) throws ServletException {

    registerOpenEntityManagerInViewFilter(servletContext);
    super.onStartup(servletContext);

}

private void registerOpenEntityManagerInViewFilter(ServletContext servletContext) {
    OpenEntityManagerInViewFilter viewFilter = new OpenEntityManagerInViewFilter();
    viewFilter.setEntityManagerFactoryBeanName("entityManagerFactory");
    FilterRegistration.Dynamic registration = servletContext.addFilter("openEntityManagerInView",
            new OpenEntityManagerInViewFilter());
    registration.addMappingForUrlPatterns(null, false, "/*");

}

@Override
protected Class<?>[] getRootConfigClasses() {
    return new Class<?>[]{Config.class, SecurityConfig.class};
}

@Override
protected Class<?>[] getServletConfigClasses() {
    return new Class<?>[]{WebConfig.class};
}

@Override
protected String[] getServletMappings() {
    return new String[]{"/"};
}

}

Below is the entity in question. I've omitted the getters and setters.

@Entity
@Table(name = "film")
public class Film {

@Id
@GeneratedValue
@Column(name = "film_id")
private int filmId;
@Column(name = "title")
private String title;
@Column(name = "description")
private String description;
@Column(name = "release_year")
private int releaseYear;
@ManyToOne
@JoinColumn(name = "language_id")
private Language language;
@ManyToOne
@JoinColumn(name = "original_language_id")
private Language originalLanguage;
@Column(name = "rental_duration")
private int rentalDuration;
@Column(name = "rental_rate")
private double rentalRate;
@Column(name = "length")
private int length;
@Column(name = " replacement_cost")
private double replacementCost;
@Column(name = "rating")
private String rating;
@Column(name = "special_features")
private String specialFeatures;
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "last_update")
private Date lastUpdate;
@OneToMany(mappedBy = "film", cascade = CascadeType.ALL)
private List<Inventory> inventories;

.........
}

Below is my config for my JPA stuff.

@Configuration
@EnableTransactionManagement
public class Config {

@Bean(name = "entityManagerFactory")
public EntityManagerFactory entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
    HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
    HibernateJpaDialect hibernateJpaDialect = new HibernateJpaDialect();
    emf.setDataSource(dataSource());
    emf.setPackagesToScan("com");
    emf.setJpaDialect(hibernateJpaDialect);
    emf.setJpaVendorAdapter(hibernateJpaVendorAdapter);
    /* Map<String,String> props = new HashMap<>();
     props.put("hibernate.show_sql", "true");
     emf.setJpaPropertyMap(props);*/
    emf.afterPropertiesSet();
    return emf.getObject();
}

@Bean(name = "transactionManager")
public PlatformTransactionManager transactionManager() throws IOException {
    JpaTransactionManager jtm
            = new JpaTransactionManager();
    jtm.setEntityManagerFactory(entityManagerFactory());
    jtm.setDataSource(dataSource());
    return jtm;
}

@Bean(name = "dataSource")
public DriverManagerDataSource dataSource() {
    DriverManagerDataSource dds = new DriverManagerDataSource();
    dds.setDriverClassName("com.mysql.jdbc.Driver");
    dds.setUrl("jdbc:mysql://localhost/test");
    dds.setUsername("username");
    dds.setPassword("password");
    return dds;
}

}

Below is my web config

@Configuration
@EnableWebMvc
@ComponentScan("com")
public class WebConfig {

@Bean
public ViewResolver viewResolver() {
    InternalResourceViewResolver vr = new InternalResourceViewResolver();
    vr.setViewClass(JstlView.class);
    vr.setPrefix("/WEB-INF/jsp/");
    vr.setSuffix(".jsp");
    vr.setExposeContextBeansAsAttributes(true);
    return vr;
}

}

Below is my security config.

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
public void configureAuthenticationManagerBuilder(AuthenticationManagerBuilder auth) throws Exception {
    auth
            .inMemoryAuthentication()
            .withUser("user").password("password").roles("USER");
}

@Override
protected void configure(HttpSecurity http) throws Exception {
      http.authorizeRequests()
     .antMatchers("/**").access("hasRole('ROLE_USER')")
     .and().formLogin().loginPage("/login")
     .usernameParameter("username")
     .passwordParameter("password")
     .defaultSuccessUrl("/index", true).failureUrl("/login?error")
     .loginProcessingUrl("/j_spring_security_check");

}

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/login");
}

}

My Dao class below.

@Repository
public class FilmDao {

    @PersistenceContext
    private EntityManager em;

    public Film getFilm(int filmId) {
        Film film = em.find(Film.class, filmId);
        return film;
    }

}

Service class below which is called by my controllers.

@Service
public class FilmService {

    @Autowired
    private FilmDao filmDao;

   @Transactional
    public Film getFilm(int filmId) {
        Film film = filmDao.getFilm(filmId);
        return film;
    }

}

Answer 1

I got the same problem. SecurityFilter has default filter order -100 and that is the reason. You have to put openEntityManagerInViewFilter (which order is equal to 0 or something like that) before the SecurityFilter (security filter checks user for roles and fails). Try to register filter with order=-101. You can use either your approach with ServletContext or the following I used (just insert in any bean marked with @Configuration annotation):

@Configuration
public class WebConfig {
@Bean
    public FilterRegistrationBean openEntityManagerInViewFilterRegistration(SecurityProperties properties) {

        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(openEntityManagerInViewFilter());
        registration.addUrlPatterns("/*");
        registration.setOrder(properties.getFilterOrder()-1);
        registration.setName("openEntityManagerInViewFilter");
        registration.setDispatcherTypes(DispatcherType.REQUEST, DispatcherType.ASYNC);
        return registration;
    }

    @Bean(name = "openEntityManagerInViewFilter")
    public OpenEntityManagerInViewFilter openEntityManagerInViewFilter() {
        return new OpenEntityManagerInViewFilter();
    }
}

Main entry point (main class)

@Configuration
@SpringBootApplication
public class Application  extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    static final Logger log = LoggerFactory.getLogger(Application.class);
    public static void main(String[] args) {

        ConfigurableApplicationContext run = SpringApplication.run(Application.class);
        log.info(Arrays.toString(run.getEnvironment().getActiveProfiles()));
    }

}

Answer 2

You can simply call film.getInventories() somewhere inside your @Transactional service layer. This give you more control instead of eager loading on JPA level:

@Service
public class FilmService {

   @Autowired
   private FilmDao filmDao;

   @Transactional
    public Film getFilm(int filmId, boolean loadInventories) {
        Film film = filmDao.getFilm(filmId);
        if(loadInventories){ film.getInventories(); }
        return film;
    }
}

Since it would need another round-trip to DB i would recommend to add some caching.

You can also add generic field loading functionality like this:

   @Transactional
    public Film getFilm(int filmId, String[] propertiesToLoad) {
        Film film = filmDao.getFilm(filmId);
        BeanWrapper bw = new BeanWrapperImpl(item);
        for (String propertyName : propertiesToLoad) {
           bw.getPropertyValue(propertyName);
        }
        return film;
    }

Answer 3

The problem is very simple.

In your jsp your are returning film from public Film getFilm(int filmId) In the jsp page you probably doing something like :

<jsp:getProperty name="film" property="inventories" />

You are trying to get invetories but it was lazy loading and session is already closed(@Transactional annotation open session and close when method is finished)

So either you will create new method to get inverntories by filmId or make it eager loading:

@OneToMany(fetch=FetchType.EAGER, mappedBy = "film", cascade = CascadeType.ALL)
private List<Inventory> inventories;

Answer 4

Maybe, in this case, it's much more simple to abandon OpenSessionInView/OpenEntityManagerInView, and use

<property name="hibernate.enable_lazy_load_no_trans" value="true" />

in persistence.xml (or configure it programmatically).

This property has a similar behavior (and pros/cons) of OSIV, except that a new EntityManager can potentially be instantiated on each lazy load trigger, instead of having a lone and long scoped one, so you have to be aware of it to properly manage the persistence context(s).

However, this never fails with no Session.

Answer 5

Transaction was completed before JSP is rendered and hence Hibernate Session is no longer available for lazily loading the said property.

Alternative solution (which does not require the use of the OEMIV filter): if you wish to retain lazy loading for the said collection property elsewhere in your code, create a separate finder method findFilmWithInventories for retrieving the entity and do a join fetch query to eagerly load the said collection.
