Spring Boot读取jar包文件错误解决

从jar包中读取classpath下文件出错：

java.io.FileNotFoundException: class path resource [conf/sendofd.xml] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/home/wuhui/component/da
ta/data-query-3.0.1.jar!/BOOT-INF/classes!/conf/sendofd.xml

解决办法：

Resource resource = new ClassPathResource("/" + relativePath);
        InputStream fileInputStream = null;
        try {
            fileInputStream = resource.getInputStream();
        } catch (IOException e) {
            e.printStackTrace();
        }
