因为是工作中遇到的问题，所以在自己电脑写了个简单例子还原记录一下

只在本地能load，不能在环境上load的代码写法：

import org.springframework.core.io.ClassPathResource;

import java.io.File;
import java.io.IOException;
public static void main(String[] args) {
        try {
            ClassPathResource classPathResource = new ClassPathResource("config/account_status.yml");//该路径基于src/resources
            File file = classPathResource.getFile();
            System.out.println(file.getName());
        } catch (IOException e) {
            System.out.println("file can't find");
            e.printStackTrace();
        }

    }

问题出现原因：这是因为打包后Spring试图访问文件系统路径，但是无法访问jar中的路径

解决方法，将以上代码改成如下

import org.apache.commons.io.FileUtils;
import org.springframework.core.io.ClassPathResource;

import java.io.File;
import java.io.IOException;
import java.io.InputStream;

public class TestFileLoadIssue {
    public static void main(String[] args) {
        try {
            ClassPathResource classPathResource = new ClassPathResource("config/account_status.yml");
            InputStream inputStream = classPathResource.getInputStream();
            File file = new File(classPathResource.getFilename());
            FileUtils.copyInputStreamToFile(inputStream,file);
            System.out.println(file.getName());
        } catch (IOException e) {
            System.out.println("file can't find");
            e.printStackTrace();
        }
    }

}
