spring-从普通java类取得注入spring Ioc容器的对象的方案

1.启动服务时通过spring容器的监听器（继承ContextLoaderListener 监听器的方法）

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);
    }

}

2.实现appctionContextaware的方法

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);
    }
}  

将SpringUtil注入spring配置文件

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

获取

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