創建ClassPathXmlApplicationContext時java.lang.ExceptionInInitializerError

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestAdvice1 {
	public static void main(String[] args) {
		String configPath = "com/baobaotao/advice/beans.xml";
		ApplicationContext ctx = new ClassPathXmlApplicationContext(configPath);
		Waiter waiter = (Waiter)ctx.getBean("waiter1");
		waiter.greetTo("John");
	}
}

報錯：

反覆檢查了好多遍，就是沒有發現那裏出錯。

最後才發現是eclipse的一個小配置導致的。

我把spring的jar包配置爲user library ，勾選了system library 選項，導致報錯。把該選項去掉就可以了。
