如何解决由SPRING中的FileNotFoundException引起的BeanDefinitionStoreException？

Question

我正在尝试使用SPRING在Triangle bean中调用方法draw（）的活动。 但是，当我尝试访问spring.xml文件时，遇到了一个错误。

错误是：

Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [spring.xml]; nested exception is java.io.FileNotFoundException: class path resource [spring.xml] cannot be opened because it does not exist

这是主要的SpringApplication.java：

package org.spring.application;

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

public class SpringApplication
{

    public static void main(String[] args)
    {
        AbstractApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
        Triangle triangle = (Triangle) context.getBean("Triangle");
        triangle.draw();
    }

}

这是spring.xml中的代码

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
        <bean id="Triangle" class="org.spring.application.Triangle"/>
</beans>

这是项目文件夹： Project Folder

我正在使用NetBeans IDE。 我还包括了Spring Library and Components Logging。 有人可以帮我指出我做错了什么吗？ 谢谢。

Answer 1

您需要添加软件包。 new ClassPathXmlApplicationContext("spring.xml"); 应该是new ClassPathXmlApplicationContext("org/spring/application/spring.xml");

Answer 2

您应该将spring.xml在资源文件夹中。 使用以下结构：
