我是靠谱客的博主善良过客，最近开发中收集的这篇文章主要介绍打包运行报错：Caused by: java.io.FileNotFoundException: class path resource [properties/image.properties/]，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

项目打包后windows运行报错：

Caused by: java.io.FileNotFoundException: class path resource [properties/image.properties/] cannot be opened because it does not exist

具体的异常信息如下（我这里是一个war包）：

并且在开发工具中运行无异常，查看自己的本地target中是否存在该文件（我的存在无异常）；若不存在：进入开发工具检查此文件是否在src目录下；如果存在则大致原因有两种：

在这里插入图片描述

一、获取文件的方式不正确（***.getInputStream();）

在这里插入图片描述
错误举例：

@Value("classpath:test/billingconfig-file.xml")
private Resource resourceFile; // 注入计费点文件资源

JAXBContext context = JAXBContext.newInstance(BillingModelList.class);
Unmarshaller unmarshaller = context.createUnmarshaller();
BillingModelList billingModelList = (BillingModelList) unmarshaller.unmarshal(resourceFile.getFile());

修改正确：

@Value("classpath:test/billingconfig-file.xml")
private Resource resourceFile; // 注入计费点文件资源

JAXBContext context = JAXBContext.newInstance(BillingModelList.class);
Unmarshaller unmarshaller = context.createUnmarshaller();
BillingModelList billingModelList = (BillingModelList) unmarshaller.unmarshal(resourceFile.getInputStream());
