问题

spring boot项目上传到Linux服务器后，头像上传后报404。但是我的打包的jar包在idea客户端运行是没问题的

解决

@Overridepublic void addResourceHandlers(ResourceHandlerRegistry registry) {//获取jar包所在目录ApplicationHome h = new ApplicationHome(getClass());File jarF = h.getSource();//在jar包所在目录下生成一个upload文件夹用来存储上传的图片String dirPath = jarF.getParentFile().toString()+"\\static\\upload\\";registry.addResourceHandler("/upload/**").addResourceLocations("file:"+dirPath);}

修改

将String dirPath = jarF.getParentFile().toString()+"\\static\\upload\\";修改为String dirPath = jarF.getParentFile().toString()+"/static/upload/";

问题解决
