package com.alimama.config;import org.springframework.context.ApplicationContext;/** * 上下文獲取工具類 * @author mengfeiyang * */public class SpringContextUtil { private static ApplicationContext applicationContext; public static void setApplicationContext(ApplicationContext context) { applicationContext = context; } public static Object getBean(String beanId) { return applicationContext.getBean(beanId); }} |
2、在啟動入口類中注入applicationContext
