    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        ApplicationUtil.applicationContext = applicationContext;
    }

    /**
     * 獲取Spring上下文
     * @return
     */
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    /**
     * 獲取Spring Bean
     * @param name
     * @return
     * @throws BeansException
     */
    public static Object getBean(String name) throws BeansException {
        return applicationContext.getBean(name);
    }
}

在Spring配置文件中手動配置ApplicationUtil Bean

<bean id="applicationUtil" class="com.nb.soa.common.util.ApplicationUtil"></bean>
