spring-从普通java类取得注入spring Ioc容器的对象的方案

public class ListenerSpringContext extends ContextLoaderListener {
    private final Logger log = LoggerFactory.getLogger(ListenerSpringContext.class);

    public void contextInitialized(ServletContextEvent event) {
        log.info("init ListenerSpringContext...");
        super.contextInitialized(event);
        ApplicationContext applicationContext = WebApplicationContextUtils.getWebApplicationContext(event.getServletContext());
　　　　　//自己手动保留一个spring注入的容器
        UtilsSpringContext.setApplicationContext(applicationContext);
    }

}

package com.ceopen.eoss.spring;  
  
import org.springframework.beans.BeansException;  
import org.springframework.context.ApplicationContext;  
import org.springframework.context.ApplicationContextAware;  
  
public class SpringUtil implements ApplicationContextAware {  
      
    private static ApplicationContext applicationContext;  
      
    @Override  
    public void setApplicationContext(ApplicationContext context)  
        throws BeansException {  
        SpringUtil.applicationContext = context;  
    }  
    public static Object getBean(String name){  
        return applicationContext.getBean(name);  
    }  
}  

<bean id="spring" class="com.ceopen.eoss.spring.SpringUtil" />  

ICBMission icbMission = (ICBMission)SpringUtil.getBean("ICBMission");
