springboot 使用上下文获取bean

package cn.eangaie.appcloud.util;
import org.springframework.context.ApplicationContext;
public class SpringContextUtil {
  private static ApplicationContext applicationContext;

  //获取上下文
  public static ApplicationContext getApplicationContext() {
    return applicationContext;
  }

  //设置上下文
  public static void setApplicationContext(ApplicationContext applicationContext) {
    SpringContextUtil.applicationContext = applicationContext;
  }

  //通过名字获取上下文中的bean
  public static Object getBean(String name){
    return applicationContext.getBean(name);
  }

  //通过类型获取上下文中的bean
  public static Object getBean(Class<?> requiredType){
    return applicationContext.getBean(requiredType);
  }
}

public class AppcloudApplication {
  public static void main(String[] args) {
    ApplicationContext context=SpringApplication.run(AppcloudApplication.class, args);
    SpringContextUtil.setApplicationContext(context);
  }
}

MessageTemplateController messageTemplateController= (MessageTemplateController) SpringContextUtil.getBean("messageTemplateController");
