springboot 获取路径

@PostConstructpublic void setup() {try {// jar包所在目录  /Users/mashanshanString path = this.getClass().getProtectionDomain().getCodeSource().getLocation().getPath();System.out.println("path:" + path);  // file:/Users/mashanshan/manual-admin-0.0.1-SNAPSHOT.jar!/BOOT-INF/classes!/ApplicationHome home = new ApplicationHome(getClass());File jarFile1 = home.getSource();String path0 = jarFile1.getParentFile().toString();System.out.println("path0: " + path0);  // /Users/mashanshanString path1 = ManualController.class.getClassLoader().getResource("").getPath();System.out.println("path1: " + path1);  // file:/Users/mashanshan/manual-admin-0.0.1-SNAPSHOT.jar!/BOOT-INF/classes!/String path2 = System.getProperty("user.dir");System.out.println("path2:" + path2);  // /Users/mashanshanFile path3 = new File(ResourceUtils.getURL("classpath:").getPath());System.out.println("path3:" + path3.getAbsolutePath());  // /Users/mashanshan/file:/Users/mashanshan/manual-admin-0.0.1-SNAPSHOT.jar!/BOOT-INF/classes!File path4 = new File("");System.out.println("path4:" + path4.getAbsolutePath());  ///Users/mashanshan} catch (FileNotFoundException e) {throw new RuntimeException(e);}}

开发环境运行输出:
path:/Users/mashanshan/gitresp/manual-server/manual-admin/target/classes/
path0: /Users/mashanshan/gitresp/manual-server/manual-admin/target
path1: /Users/mashanshan/gitresp/manual-server/manual-admin/target/classes/
path2:/Users/mashanshan/gitresp/manual-server
path3:/Users/mashanshan/gitresp/manual-server/manual-admin/target/classes
path4:/Users/mashanshan/gitresp/manual-server

直接运行jar包输出:
path:file:/Users/mashanshan/manual-admin-0.0.1-SNAPSHOT.jar!/BOOT-INF/classes!/
path0: /Users/mashanshan
path1: file:/Users/mashanshan/manual-admin-0.0.1-SNAPSHOT.jar!/BOOT-INF/classes!/
path2:/Users/mashanshan
path3:/Users/mashanshan/file:/Users/mashanshan/manual-admin-0.0.1-SNAPSHOT.jar!/BOOT-INF/classes!
path4:/Users/mashanshan
