SessionFactory的自动装配没有发生

标签： spring hibernate dependency-injection wicket

我有一个项目：

  • 春天：4.1.7
  • Hibernate：4.3.10
  • Wicket：6.20.0

我正在努力让Hibernate和spring和wicket很好地玩耍

我有以下代码：

初始化？扩展WebApplication 

@Override
public void init()
{
    super.init();
    getComponentInstantiationListeners().add(new SpringComponentInjector(this));
}

PersonDao的

@Transactional
@Repository
public class PersonDao {

    @Autowired
    private SessionFactory sessionFactory;



    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }



    public int count(){

        Criteria criteria = sessionFactory.getCurrentSession().createCriteria(Person.class);
        return 1;
    }
}

人

@Entity
@Table(name = "person")
public class Person {

    @Id
    @GeneratedValue
    @Column(name = "id")
    private Integer id;
    @Column(name = "first_name")
    private String firstName;
    @Column(name = "last_name")
    private String lastName;

    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getFirstName() {
        return firstName;
    }
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
}

的AppConfig 

@Import({RepositoryConfig.class})
@Configuration
public class AppConfig
{
    //<context:property-placeholder location="classpath:application.properties"></context:property-placeholder>
    @Bean
    public PropertyPlaceholderConfigurer getPropertyPlaceholderConfigurer()
    {
        PropertyPlaceholderConfigurer ppc = new PropertyPlaceholderConfigurer();
        ppc.setLocation(new ClassPathResource("application.properties"));
        ppc.setIgnoreUnresolvablePlaceholders(true);
        return ppc;
    }
}

RepositoryConfig 

@Configuration
@ComponentScan("org.hibernate.dao")
public class RepositoryConfig
{

    @Value("${jdbc.driverClassName}")     private String driverClassName;
    @Value("${jdbc.url}")                 private String url;
    @Value("${jdbc.username}")             private String username;
    @Value("${jdbc.password}")             private String password;

    @Value("${hibernate.dialect}")         private String hibernateDialect;
    @Value("${hibernate.show_sql}")     private String hibernateShowSql;
    @Value("${hibernate.hbm2ddl.auto}") private String hibernateHbm2ddlAuto;

    @Bean()    
    public DataSource getDataSource()
    {
        DriverManagerDataSource ds = new DriverManagerDataSource();        
        ds.setDriverClassName(driverClassName);
        ds.setUrl(url);
        ds.setUsername(username);
        ds.setPassword(password);        
        return ds;
    }

    @Bean
    @Autowired
    public HibernateTransactionManager transactionManager(SessionFactory sessionFactory)
    {
        HibernateTransactionManager htm = new HibernateTransactionManager();
        htm.setSessionFactory(sessionFactory);
        return htm;
    }

    @Bean
    @Autowired
    public HibernateTemplate getHibernateTemplate(SessionFactory sessionFactory)
    {
        HibernateTemplate hibernateTemplate = new HibernateTemplate(sessionFactory);
        return hibernateTemplate;
    }


    @Bean(name = "sessionFactory")
    public SessionFactory getSessionFactory()
    {
          LocalSessionFactoryBuilder sessionBuilder = new LocalSessionFactoryBuilder(getDataSource());

            sessionBuilder.addAnnotatedClasses(User.class);

            return sessionBuilder.buildSessionFactory();
    }

    @Bean
    public Properties getHibernateProperties()
    {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", hibernateDialect);
        properties.put("hibernate.show_sql", hibernateShowSql);
        properties.put("hibernate.hbm2ddl.auto", hibernateHbm2ddlAuto);

        return properties;
    }
}

hibernate.show_sql=false
hibernate.hbm2ddl.auto=create-drop

我在第20行的PersonDao中得到一个空指针，这是sessionFactory为null，这意味着我没有得到sessionFactory自动装配，这是我第一次尝试让非XML配置工作，我想我错过了一些东西，帮助非常感谢。
