java - 如何从服务层访问spring管理的bean

Question

我无法在服务层获取spring bean(ServiceContext.getBean("beanName"))。不过，我可以在 servlet 中获取 bean。我在下面的类(class)中做错了什么？

package com.ekaplus.presentation.common;

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

public class ServiceContext implements ApplicationContextAware{

    private static ApplicationContext applicationContext;       

    @SuppressWarnings("static-access")
    public  void setApplicationContext(ApplicationContext ctx)throws BeansException {
        this.applicationContext=ctx;        
    }
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }
    public static Object getBean(String beanName)
    {
        return applicationContext.getBean(beanName);
    }

}

尝试在没有静态访问的情况下进行操作。这样的smt(仅用于测试)

class ServiceContext {
    public static Object getBean(final String beanName){
        return new ApplicationContextAware(){
            Object res;
            @Override
            public void setApplicationContext(ApplicationContext applicationContext)
                    throws BeansException {
                res = applicationContext.getBean(beanName);
            }

            Object getBean(){
                return res;
            }

        }.getBean();
    }
}
