如何解決 SPRING 中 FileNotFoundException 引起的 BeanDefinitionStoreException？（Netbeans IDE）

Question

我正在使用 spring 創建一個非常簡單的 java 應用程序。 但是應用程序無法打開配置文件（config.xml）。

我使用的是 nebeans IDE 8.2 jdk8 版本

這是代碼：

package com.prasad.spring.springcore;


import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.io.*;
import java.util.*;
import java.lang.*;

/**
 *
 * @author Prasad-pc
 */
public class Test{
    public static void main(String args[]){
        ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("config.xml");  //  configuration file name
        Employee emp = (Employee) ctx.getBean("emp");
        System.out.println("Employee ID: " + emp.getId());
        System.out.println("Employee Name: " + emp.getName());
    }
}

我得到的錯誤是：

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

“config.xml”存在於 src/main/java 目錄中

Answer 1

config.xml文件必須在src/main/resources目錄中，而在上述情況下它在src/main/java

Answer 2

src/main/java應該只包含 Java 類。 那里的任何其他內容都將被忽略。

src/main/resources應包含您希望以當前形式包含的任何內容，例如 XML 文件。
