工具类：

public class SpringBeanFactoryUtils implements ApplicationContextAware {
  private static ApplicationContext appCtx;
  public static ApplicationContext getApplicationContext() {
    return appCtx;
  }
  @Override
  public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
    appCtx = applicationContext;
  }
  public static Object getBean(String beanName) {
    return appCtx.getBean(beanName);
  }
}

注入spring： 

<bean id="springBeanFactoryUtils" class="test.utils.SpringBeanFactoryUtils"/>

获取bean：

TestService testService = (TestService ) SpringBeanFactoryUtils.getBean("testService Impl");
