How to get spring application context object reference? - See more at: http://www.java2novice.com/sp

This page gives an example to get spring application context object with in non spring managed classes as well. It is not possible to have all classes as spring managed classes, in such classes you need to get spring application context object. This can be achieved by using ·ApplicationContextAware· interface. Here are the steps to achieve application context object:
Create a new class and implement ApplicationContextAware method and its unimplemented method as shown below:

package com.java2novice.spring;import org.springframework.beans.BeansException;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationContextAware;public class ApplicationContextProvider implements ApplicationContextAware{    private static ApplicationContext context;    public ApplicationContext getApplicationContext() {        return context;    }    @Override    public void setApplicationContext(ApplicationContext ac)            throws BeansException {        context = ac;    }}

Declate above bean in your applicationContext.xml file as shown below:

<bean id="applicationContextProvder"                        class="com.java2novice.spring.ApplicationContextProvider"/>

And finally here is the code to access application context and getting bean reference:

ApplicationContextProvider appContext = new ApplicationContextProvider();//肯定不是自己new出来的，肯定是从ApplicationContext中获取的TestBean tb = appContext.getApplicationContext().getBean("testBean", TestBean.class);
