spring中使用ApplicationContext

声明一个SpringUtil,并且实现ApplicationContextAware接口

 private static ApplicationContext applicationContext;
    
    @Override
    public void setApplicationContext(ApplicationContext context)
        throws BeansException {
    	SpringUtil.applicationContext = context;
    }
    public static Object getBean(String name){
        return applicationContext.getBean(name);
    }
    public static <T> T getBean(Class<T> requiredType) {
        return applicationContext.getBean(requiredType);
    }

在spring config文件中注入这个SpringUtil类即可
