spring獲取從context中獲取bean失敗的解決方案

applicationContext-xml中加入了某個bean

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
  xmlns:tx="http://www.springframework.org/schema/tx" xmlns:p="http://www.springframework.org/schema/p"
  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"

  default-lazy-init="true">

<bean class="MyApplicationContextUtil" lazy-init="false"></bean>
</beans>

MyApplicationContextUtil.java


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


public class MyApplicationContextUtil implements ApplicationContextAware {
  private static ApplicationContext context;


  public void setApplicationContext(ApplicationContext contex)
    throws BeansException {
    this.context=contex;
  }
  public static ApplicationContext getContext(){
    return context;
  }
  
  public static ApplicationContext getApplicationContext() {
  return getContext();
  }
}

用spring3 如果不將lazy-init 設定為false,spring 啟動時不會自動去MyApplicationContextUtil  執行setApplicationContext
