spring boot 获取spring容器中的bean

新建一个类内容如下：
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

@Component
public class ApplicationContextUtil implements ApplicationContextAware {
    private static ApplicationContext context;

    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        context = applicationContext;
    }

    public static ApplicationContext getApplicationContext() {
        return context;
    }
}

使用ApplicationContext获得bean:

ApplicationContext applicationContext = ApplicationContextUtil.getApplicationContext();
UrlMapperRecord urlMapperRecord =(UrlMapperRecord) applicationContext.getBean("urlMapperRecord");
