SpringBoot项目打包成jar后读取文件的大坑,使用ClassPathResource获取classpath下文件失败
本地测试文件可以正常读取,但打包成jar包传到服务器上就无法获取了,报错信息是:class path resource [xxxx] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:xxxx.jar!/BOOT-INF/classes!xxxx,话不多说,先看正确的获取方法:使用PathMatchingResourcePatternResolver
