关于Spring中ApplicationContext加载机制中BeanFactory类

最近看到使用的BeanFactory是关于Spring中ApplicationContext加载机制的,同时深入地查看了BeanFactory

类.

package com.chinasofti.whb.util.util;

import org.springframework.beans.BeansException;

import org.springframework.context.ApplicationContext;

import org.springframework.context.ApplicationContextAware;

public class BeanFactory implements ApplicationContextAware {

// Spring应用上下文环境

private static ApplicationContext applicationContext;

/**

* 实现ApplicationAware接口的回调方法,设置上下文环境

*

* @param application

*/

public void setApplicationContext(ApplicationContext applicationContext)

throws BeansException {

// BeanFactory.applicationContext = applicationContext;

this.applicationContext = applicationContext;

}

/**

* return applicationContext

*/

public static ApplicationContext getApplicationContext() {

return applicationContext;

}

/**

* 获取对象

*

* @param name

* @return Object

* @throws BeansException

*/

public static Object getBean(String name) throws BeansException {

checkApplication();

return applicationContext.getBean(name);

}

/**

* 获取对象

*

* @param name

* @param requiretype

* @return Object

* @author BeansException

*/

public static Object getBObject(String name, Class requiretype)

throws BeansException {

checkApplication();

return applicationContext.getBean(name, requiretype);

}

public static void cleanApplication() {

applicationContext = null;

}

/**

* 检查spring注入

*/

public static void checkApplication() {

if (applicationContext == null) {

throw new IllegalStateException("Spring未注入,请在配置文件中注入");

}

}

}
