Spring获取ApplicationContext对象工具类的实现方法

(1)实现的工具类:

package com.util; 
 
import org.springframework.context.ApplicationContext; 
import org.springframework.context.support.ClassPathXmlApplicationContext; 
 
final public class ApplicationContextUtil { 
 
  private static ApplicationContext ac=null; 
   
  private ApplicationContextUtil(){ 
     
  } 
   
  static{ 
    ac=new ClassPathXmlApplicationContext("applicationContext.xml"); 
  } 
   
  public static ApplicationContext getApplicationContext(){ 
    //获得返回的容器对象 
    return ac; 
  } 
   
} 

(2)使用方法:

public static void getByUtil(){ 
    ApplicationContextUtil.getApplicationContext().getBean("userService"); 
  }
