JavaConfig - Spring JPA Hibernate - @EnableTransactionManagement

Question

Я пытаюсь настроить демонстрационный проект с Spring4, Hibernate и HSQLDB-Database с помощью JavaConfig и Tomcat8-Server. Я следил за несколькими учебниками, но все закончилось тем же самым исключением.

Вот моя конфигурация:

@Configuration 
@EnableTransactionManagement 
@Slf4j 
public class DatasourceConfig 
{ 

@Bean 
DataSource dataSource() 
{ 
    DataSource dataSource = null; 
    JndiTemplate jndi = new JndiTemplate(); 
    try 
    { 
     dataSource = (DataSource) jndi.lookup("java:comp/env/jdbc/testdb"); 
    } 
    catch (NamingException e) 
    { 
     log.error(e.toString()); 
    } 
    return dataSource; 
} 

    @Bean 
    public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean() 
    { 
     LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean(); 
     entityManagerFactoryBean.setDataSource(dataSource()); 
     entityManagerFactoryBean.setPackagesToScan("packageNameWithModels"); 

     JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter(); 
     entityManagerFactoryBean.setJpaVendorAdapter(vendorAdapter); 
     entityManagerFactoryBean.setJpaProperties(hibProperties()); 

     return entityManagerFactoryBean; 
    } 

    @Bean 
    public PlatformTransactionManager transactionManager() 
    { 
     JpaTransactionManager transactionManager = new JpaTransactionManager(); 
     transactionManager.setEntityManagerFactory(entityManagerFactoryBean().getObject()); 
     return transactionManager; 
    } 



    @Bean 
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation(){ 
     return new PersistenceExceptionTranslationPostProcessor(); 
    } 


    private Properties hibProperties() 
    { 
     Properties properties = new Properties(); 
     properties.put("hibernate.dialect", "org.hibernate.dialect.HSQLDialect"); 
     properties.put("hibernate.show_sql", "true"); 
     return properties;   
    }  

} 

Maven установка работает как шарм, но когда я пытаюсь запустить tomcat8-сервер я получаю сообщение об ошибке последующей:

В моем понимании @ EnableTransactionManagment-annotation ищет компонент-менеджер транзакций, находит его, но не может найти диспетчер сущности, который задается кодом:

transactionManager.setEntityManagerFactory(entityManagerFactoryBean().getObject()); 

Может быть, кто-то может мне помочь? Заранее спасибо Pete

Answer 1

Не знаете, в чем проблема с вашей установкой. Попробуйте эту настройку. Удалите свои методы entityManagerFactoryBean, transactionManager и hibProperties.

@Bean 
@Autowired 
public EntityManagerFactory entityManagerFactory(DataSource dataSource) { 
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter(); 
    vendorAdapter.setGenerateDdl(false); 

    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean(); 
    factory.setJpaVendorAdapter(vendorAdapter); 
    factory.setPackagesToScan("com.company.project"); 
    factory.setDataSource(dataSource); 

    Properties jpaProperties = new Properties(); 
    jpaProperties.put("hibernate.dialect", "org.hibernate.dialect.HSQLDialect"); 
    jpaProperties.put("hibernate.show_sql", true); 
    factory.setJpaProperties(jpaProperties); 

    factory.afterPropertiesSet(); 
    return factory.getObject(); 
} 

@Bean 
@Autowired 
public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) { 
    JpaTransactionManager jpaTransactionManager = new JpaTransactionManager(entityManagerFactory); 
    return jpaTransactionManager; 
} 

Answer 2

Я нашел эту проблему, я имел устаревшую зависимость в pom.xml определено:

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-dao</artifactId> 
    <version>2.0.8</version> 
</dependency> 

После того как я убрал эту зависимость он работает. В любом случае, спасибо за помощь!
