ApplicationContextAware

实现ApplicationContextAware接口以获取静态的ApplicationContext对象：

package pers.spring.demo.common.support.util;

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

/**
 * SpringUtil implements ApplicationContextAware
 */
@Component
public class SpringUtil implements ApplicationContextAware {

    public static ApplicationContext applicationContext;

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