如何解決由SPRING中的FileNotFoundException引起的BeanDefinitionStoreException？

Question

我正在嘗試使用SPRING在Triangle bean中調用方法draw（）的活動。 但是，當我嘗試訪問spring.xml文件時，遇到了一個錯誤。

錯誤是：

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

    ... 13 more

這是主要的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();
    }

}

這是spring.xml中的代碼

<?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>

這是項目文件夾： Project Folder

我正在使用NetBeans IDE。 我還包括了Spring Library and Components Logging。 有人可以幫我指出我做錯了什么嗎？ 謝謝。

Answer 1

您需要添加軟件包。 new ClassPathXmlApplicationContext("spring.xml"); 應該是new ClassPathXmlApplicationContext("org/spring/application/spring.xml");

Answer 2

您應該將spring.xml在資源文件夾中。 使用以下結構：
