Answer 1

一、ApplicationContextAware接口
package org.springframework.context;

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.Aware;
import org.springframework.context.ApplicationContext;

public interface ApplicationContextAware extends Aware {
void setApplicationContext(ApplicationContext var1) throws BeansException;
}

二、ServletContextAware 接口
package org.springframework.web.context;

import javax.servlet.ServletContext;
import org.springframework.beans.factory.Aware;

public interface ServletContextAware extends Aware {
void setServletContext(ServletContext var1);
}

三、InitializingBean 接口
package org.springframework.beans.factory;

public interface InitializingBean {
void afterPropertiesSet() throws Exception;
}

四、ApplicationListener<ApplicationEvent> 接口
package org.springframework.context;

import java.util.EventListener;
import org.springframework.context.ApplicationEvent;

public interface ApplicationListener<E extends ApplicationEvent> extends EventListener {
void onApplicationEvent(E var1);
}
