测试类:
package com.njty.aop;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class DependsHello {
public void display() {
System.out.println("this is class DependsHello depends class Hello!!");
}
public static void main(String[] args) {
ApplicationContext ac = new ClassPathXmlApplicationContext();
DependsHello dh = (DependsHello)ac.getBean("dh");
dh.display();
}
}
xml配置:
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.0.xsd">
<bean id="dh" class="com.njty.aop.DependsHello"></bean>
</beans>
出错信息:
Exception in thread "main" java.lang.IllegalStateException: BeanFactory not initialized or already closed - call 'refresh' before accessing beans via the ApplicationContext
at org.springframework.context.support.AbstractRefreshableApplicationContext.getBeanFactory(AbstractRefreshableApplicationContext.java:153)

搞不明白了,就这么个简单的小例子都错误,还找不到解决办法,很是郁闷。
哪位大侠帮助看一下,在线等,解决就给分,谢谢!

cglib.jar 加到classpath下了吗

1.不知道是楼主的Spring版本太低还是,我的版本高了点,ClassPathXmlApplicationContext有下面构造函数么?
------解决方案--------------------
不知道,看文档。

看不出来,没理由。
------解决方案--------------------
spring2.5? 但是你的这些配置好像是2.0的
xsi:schemaLocation="http://www.springframework.org/schema/beans

- Java code
Exception in thread "main" java.lang.IllegalStateException: BeanFactory not initialized or already closed - call 'refresh' before accessing beans via the ApplicationContext

可能是Spring的配置文件没有读入,cglib.jar的用处是面向切面,这里不加都可以。。。
