spring-boot全局变量的声明

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

/**
 * 全局变量
 * @author 赵亚辉

 */
@Configuration
public class SpringContextUtil implements ApplicationContextAware {

    private static ApplicationContext applicationContext;

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

    public static ApplicationContext getCtx() {
        return SpringContextUtil.applicationContext;
    }

    public static  T getBean(Class t) {
        return SpringContextUtil.applicationContext.getBean(t);
    }

}

使用的时候，直接使用这个类的getBean方法就可以了
