普通类中获取service接口并调用方法

package com.antke.website.utils;


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


public class SpringContextUtil implements ApplicationContextAware {
private static ApplicationContext applicationContext = null;

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

public static ApplicationContext  getApplicationContext(){
       return applicationContext;
    }


    public static Object getBean(String beanName){
        return applicationContext.getBean(beanName);
    }


    public static Object getBean(Class c){
        return applicationContext.getBean(c);
    }

}

在spring的配置文件中：

<bean id="springContextUtil" class="com.antke.website.utils.SpringContextUtil"></bean>

调用：

 ApplicationContext appCtx = SpringContextUtil.getApplicationContext();
 ActivityService service = (ActivityService)SpringContextUtil.getBean(ActivityService.class);
 IActivityInfoService infoService = (IActivityInfoService)SpringContextUtil.getBean(IActivityInfoService.class);
