SpringBoot的坑-01

SpringBoot裏面用這個方法ApplicationContext ac=ContextLoader.getCurrentWebApplicationContext();拿不到ac，好像只能這麼拿ac

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

@Component
public class ApplicationContextProvider implements ApplicationContextAware {

    private static ApplicationContext applicationContext;

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

    public static ApplicationContext getContext() {
        return applicationContext;
    }

}
