1、在applicationContext-bean.xml中配置

<bean id="springContextUtil" class="com.vst.search.common.util.SpringContextUtil" lazy-init="false"/>

2、新建一个类

package com.vst.search.common.util;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class SpringContextUtil implements ApplicationContextAware{
private static ApplicationContext applicationContext;

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

public static ApplicationContext getApplicationContext(){
return applicationContext;
}

public static Object getBean(String name) throws BeansException{
return applicationContext.getBean(name);
}

public static <T> T getBean(Class<T> clazz, String beanName) throws BeansException{
return applicationContext.getBean(beanName, clazz);
}

public static boolean containsBean(String name){
return applicationContext.containsBean(name);
}
}
