如何在Spring中设置全局上下文变量？

import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class GlobalContext implements ApplicationContextAware {

    private static ApplicationContext context;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) {
        context = applicationContext;
    }

    public static <T> T getBean(Class<T> beanClass) {
        return context.getBean(beanClass);
    }

    public static Object getBean(String beanName) {
        return context.getBean(beanName);
    }

    // 其他需要的全局变量或方法
}

<bean id="globalContext" class="com.example.GlobalContext" />

MyBean myBean = GlobalContext.getBean(MyBean.class);
