报错回顾

{“msg”:“class path resource [templates/animal.docx] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/home/fangyi/20220125/fangyi-admin.jar!/BOOT-INF/classes!/templates/%e7%95%9c%e7%89%a7%e5%85%bd%e5%8c%bb%e9%98%b2%e7%96%ab%e6%8a%a5%e5%91%8a.docx”,“code”:500}

原因解析

当我把项目中需要导出的文件模板放在resource下面的templates 下 打成jar包之后 显示找不到这个模板路径，可以通过修改代码中获取文件路径的方式去解决

解决方式

//第一种方式
String path = new ClassPathResource("templates/animalsInjectionWord.docx").getFile().getPath();
File file = new File(path);
//第二种方式
StringBuilder builder = new StringBuilder();
ClassPathResource classPathResource = new ClassPathResource("templates/animalsInjectionWord.docx");
InputStreamReader reader = new InputStreamReader(classPathResource.getInputStream(),"UTF-8");
BufferedReader bufferedReader = new BufferedReader(reader);
String tempContent = null;
while((tempContent = bufferedReader.readLine()) != null){
	builder.append(tempContent);
}
bufferedReader.close();
//第三种方式
ApplicationHome applicationHome = new ApplicationHome(RuoYiApplication.class);
File jarF = applicationHome.getSource();
//第四种方式
InputStream inputStream = this.getClass().getResourceAsStream("templates/animalsInjectionWord.docx");
//第五种方式
InputStream inputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("templates/animalsInjectionWord.docx");

使用完成之后别忘记关流
