SpringBoot线程通过ApplicationContext上下文获取实例

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.context.annotation.Configuration;
@Configuration
public class SpringContextUtil implements ApplicationContextAware {
    private static ApplicationContext applicationContext=null;
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        SpringContextUtil.applicationContext=applicationContext;
    }
    public static ApplicationContext getApplicationContext(){
        return applicationContext;
    }
    public static Object getBean(String beanName){
        return applicationContext.getBean(beanName);
    }
    public static Object getBean(Class c){
        return applicationContext.getBean(c);
    }
}

Service service=(Service)SpringContextUtil.getBean(Service.class);
