程序中非action获得spring容器

java类：

public class MySpringContext implements ApplicationContextAware{
  private static ApplicationContext context;//声明一个静态变量保存
  @SuppressWarnings("static-access")
  public void setApplicationContext(ApplicationContext contex) throws BeansException {
    this.context=contex;
  }
  public static ApplicationContext getContext(){
    return context;
  }

}

spring配置文件中配置：

<bean class="com.tsingsoft.basedata.sendMessage.MySpringContext"></bean>

调用类调用：

ApplicationContext app =MySpringContext.getContext();
