spring 通过中间层工具类SpringBeanFactoryUtils 实现service 注入

SpringBeanFactoryUtils  源代码：

package com.common.common.util;

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

public class SpringBeanFactoryUtils implements ApplicationContextAware {
private static ApplicationContext appCtx;
/**
* 此方法可以把ApplicationContext对象inject到当前类中作为一个静态成员变量。
* @param applicationContext ApplicationContext 对象.
* @throws BeansException
* @author wangdf
*/

public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
appCtx = applicationContext;
}

/**
* 获取ApplicationContext
* @return
* @author wangdf
*/
public static ApplicationContext getApplicationContext(){
return appCtx;
}

/**
* 这是一个便利的方法，帮助我们快速得到一个BEAN
* @param beanName bean的名字
* @return 返回一个bean对象
* @author wangdf
*/
public static Object getBean(String beanName) {
return appCtx.getBean(beanName);
}
}


spring 配置文件：



实例代码：

private IAlarmInstallPositionService alarmInstallPositionService =(IAlarmInstallPositionService)SpringBeanFactoryUtils.getBean("alarmInstallPositionService");

private IHomeDeviceService deviceService =(IHomeDeviceService)SpringBeanFactoryUtils.getBean("homeDeviceService");;
