我如何注入弹簧豆成休眠SequenceGenerator

Question

我有休眠编写自定义SequenceGenerator：

public class LoginGenerator extends SequenceGenerator { 

    @Autowired 
    ITicketService ticketService; 

    @Override 
    public Serializable generate(SessionImplementor session, Object obj) { 
     Ticket ticket = (Ticket) obj; 
     Long maxCounterOfSection = ticketService.findMaxSectionCounter(ticket 
      .getSection()); 
     maxCounterOfSection++; 
     return ticket.getSection() + "-" + maxCounterOfSection; 
    } 
} 

但是我没有这个发生器内弹簧背景！ ticketService为null。我已经为我的发电机尝试了@Component注解，但没有成功。

PS：我使用spring 3.2.0-FINAL和hibernate 3.6.10-FINAL，并且没有办法更新到hibernate4！

任何想法，任何人？

问题用ApplicationContextAware类解决，如上所述。

public class ApplicationContextProvider implements ApplicationContextAware { 
    private static ApplicationContext applicationContext; 

    @SuppressWarnings("static-access") 
    @Override 
    public void setApplicationContext(ApplicationContext applicationContext) 
      throws BeansException { 
     this.applicationContext = applicationContext; 
    } 

    public static ApplicationContext getApplicationContext() { 
     return applicationContext; 
    } 

    public static <T> T getBean(Class<T> requiredType) { 
     return applicationContext.getBean(requiredType); 
    } 

    public static <T> T getBean(String name, Class<T> requiredType) { 
     return applicationContext.getBean(name, requiredType); 
    } 
} 

在applicationContext.xml我加<bean id="applicationContextProvider" class="de.gfz.rz.spring.ApplicationContextProvider"></bean>。

这里的用法：

public class LoginGenerator extends SequenceGenerator { 

    @Override 
    public Serializable generate(SessionImplementor session, Object obj) { 
     ITicketService ticketService = ApplicationContextProvider 
      .getBean(ITicketService.class); 
     Ticket ticket = (Ticket) obj; 
     Long maxCounterOfSection = ticketService.findMaxSectionCounter(ticket 
      .getSection()); 
     maxCounterOfSection++; 
     return ticket.getSection() + "-" + maxCounterOfSection; 
    } 
}
