在普通的java类中获得spring下上文
在普通的java类中获得spring上下文
package org.company.xxx; import org.springframework.beans.BeansException; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; /** * 获取spring容器,以访问容器中定义的其他bean */ public class SpringContextUtil implements ApplicationContextAware { // Spring应用上下文环境 private static ApplicationContext applicationContext; /** * 实现ApplicationContextAware接口的回调方法,设置上下文环境 */ public void setApplicationContext(ApplicationContext applicationContext)throws BeansException { SpringContextUtil.applicationContext = applicationContext; } public static ApplicationContext getApplicationContext() { return applicationContext; } /** * 获取对象 * 这里重写了bean方法,起主要作用 * @param name * @return Object 一个以所给名字注册的bean的实例 * @throws BeansException */ public static Object getBean(String beanId) throws BeansException { return applicationContext.getBean(beanId); } }Bean配置:
<bean id="SpringContextUtil" class="org.company.xxx.SpringContextUtil" />实现了ApplicationContextAware接口,在Bean的实例化时会自动调用setApplicationContext()方法!
