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

Question

I'm creating a very simple java application using spring. But the application is not able to open the configuration file(config.xml).

I'm using nebeans IDE 8.2 jdk8 version

Here is the code:

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());
    }
}

The error I'm getting is:

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

The "config.xml" is present in src/main/java directory

Answer 1

config.xml文件必须在src/main/resources目录中，而在上述情况下它在src/main/java

Answer 2

src/main/java should only contain Java classes. Anything else in there will be ignored.

src/main/resources should contain anything that you want included in its current form, like XML files.
