public class ApplicationUtil implements ApplicationContextAware {

    private static ApplicationContext applicationContext;

    /**
     * 加载Spring配置文件时，如果Spring配置文件中所定义的Bean类实现了ApplicationContextAware接口，会自动调用该方法
     *
     * @param applicationContext
     * @throws BeansException
     */
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        ApplicationUtil.applicationContext = applicationContext;
    }

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

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

在Spring配置文件中手动配置ApplicationUtil Bean

<bean ></bean>
