普通类获取spring中的bean.....

Question

 
package com.proxy;import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.context.support.ApplicationObjectSupport;

public final class ToolSpring extends ApplicationObjectSupport { 
public static ApplicationContext applicationContext = null; 
public static String  string="";
@Override 
protected void initApplicationContext(ApplicationContext context)  throws BeansException { 
// TODO Auto-generated method stub 
super.initApplicationContext(context); 
if(ToolSpring.applicationContext == null){ 
ToolSpring.applicationContext = context; 
NetTest.applicationContext= context;
System.out.println(); 
System.out.println(); 
System.out.println("---------------------------------------------------------------------"); 
System.out.println("========ApplicationContext配置成功,在普通类可以通过调用ToolSpring.getAppContext()获取applicationContext对象,applicationContext="+applicationContext+"========"); 
System.out.println("---------------------------------------------------------------------"); 
System.out.println(); 
string ="S";
NetTest.string ="222";

new NetTest(context,"12312");
System.out.println("applicationContext="+applicationContext); 
} 
} 
public static ApplicationContext getAppContext() { 
return applicationContext; 
} 
public static Object getBean(String name){ 
return getAppContext().getBean(name); 
} 
} 
配置文件：
        <bean id="ToolSpring" class="com.proxy.ToolSpring" ></bean> 其他类的 main方法：         public static void main(String[] args) {
// ServiceDownProcessor sdp = new ServiceDownProcessor(ServletActionContext.getRequest());

System.out.println("applicationContext="+ToolSpring.getAppContext()+"|ToolSpring.getSpringServices()=");

System.out.println("applicationContext="+getApplicationContext()+"|ToolSpring.getSpringServices()=");
System.out.println("applicationContext="+ToolSpring.string+"|ToolSpring.getSpringServices()=");
System.out.println("applicationContext="+com.proxy.NetTest.string+"|ToolSpring.getSpringServices()=");
// sdp.createNodePrefixMap();

}
输出：
    applicationContext=null|ToolSpring.getSpringServices()=
applicationContext=null|ToolSpring.getSpringServices()=
applicationContext=|ToolSpring.getSpringServices()=
applicationContext=|ToolSpring.getSpringServices()=
为什么在 main方法里面去不到值呢。   很急。 知道的打下帮帮忙！！！
