如何获取springboot打成jar后的classpath

<dependency>
            <groupId>com.supconit.data.algorithm.platform</groupId>
            <artifactId>data_algorithm_util</artifactId>
            <version>1.1.00.190408-SNAPSHOT</version>
</dependency>

 String path  = new ClassPathResource("fdfs_client.conf").getFile().getAbsolutePath();
 ClientGlobal.init(path);

 ClassPathResource classPathResource = new ClassPathResource("fdfs_client.conf");
            //创建临时文件，将fdfs_client.conf的值赋值到临时文件中，创建这个临时文件的原因是springboot打成jar后无法获取classpath下文件
            String tempPath =System.getProperty("java.io.tmpdir") + System.currentTimeMillis()+".conf";
            File f = new File(tempPath);
            IOUtils.copy(classPathResource.getInputStream(),new FileOutputStream(f));
            ClientGlobal.init(f.getAbsolutePath());

Resource resource = new ClassPathResource(filePath);
File file = resource.getFile();

Resource resource = new ClassPathResource(filePath);
InputStream inputStream = resource.getInputStream();
