Hibernate AnnotationException - Spring 5 ang Hibernate 5 mapping entities

Question

I have problem after deploy my app on Tomcat. I'm using Spring 5 and Hibernate 5. I exported DB models by Hibernate Tools. My error looks like mapping problem between Hibernate models.

In my entity class i import javax.persistence from library:

[Maven: org.hibernate.javax.persistence:hibernate-jpa-2.1-api:1.0.0.Final] javax.persistence public @interface Entity

Question: What is wrong in my Hibernate models code?

Answer 1

if you check your log correctly you will see: Caused by: org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: com.example.model.Wydzialy.referaties[com.example.model.Referaty]

In your code

class Wydzialy

@OneToMany(fetch = FetchType.LAZY, mappedBy = "wydzialy")
public Set<Sprawy> getSprawies() {
    return this.sprawies;
}

class Referaty

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "ID_WYDZ")
public Wydzialy getWydzialy() {
    return this.wydzialy;
}

You need to replace Set<Sprawy> with Set<Wydzialy> to have a valid bidirectional relationship.

Also in @ManyToOne(fetch = FetchType.LAZY)

FetchType.LAZY doesn't make sense since ManyToOne is a single value association.

Answer 2

Take a look to this configuration:

@Configuration
@EnableTransactionManagement
@PropertySource(value = { "classpath:myproject.properties" })
public class HibernateConfiguration {

@Autowired
private Environment env;

@Bean
public SessionFactory  sessionFactory() {
    LocalSessionFactoryBuilder builder = new LocalSessionFactoryBuilder(dataSource());
    builder.scanPackages("com.example.model").addProperties(hibernateProperties());
    return builder.buildSessionFactory();
}

@Bean
public DataSource dataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(env.getRequiredProperty("jdbc.driverClassName"));
    dataSource.setUrl(env.getRequiredProperty("jdbc.url"));
    dataSource.setUsername(env.getRequiredProperty("jdbc.username"));
    dataSource.setPassword(env.getRequiredProperty("jdbc.password"));
    return dataSource;
}

private Properties hibernateProperties() {
    Properties properties = new Properties();
    properties.put("hibernate.dialect", env.getRequiredProperty("hibernate.dialect"));
    properties.put("hibernate.show_sql", env.getRequiredProperty("hibernate.show_sql"));
    properties.put("hibernate.format_sql", env.getRequiredProperty("hibernate.format_sql"));
    properties.put("hibernate.jdbc.batch_size", env.getRequiredProperty("hibernate.jdbc.batch_size"));
    return properties;
}

@Bean
public HibernateTransactionManager txManager() {
    return new HibernateTransactionManager(sessionFactory());
}

}

Notice the builder.scanPackages("com.example.model"), this will give you a better way to scan Entities and you no longer need to add them manually.

In your config the error might be due Entities registration order. So, with the previous config let spring to the job.

PD: you can use @Value to set your property values from the properties file

Answer 3

setAnnotatedClasses() ... sets the annotated classes. So, every time you call it, you replace the previously set classes by the new ones. Call it once, and pass all the annotated classes as argument..
