SpringBoot项目中jar发布获取jar包所在目录路径的最佳方法

        //第一种
        File path = new File(ResourceUtils.getURL("classpath:").getPath());
        if(!path.exists()) path = new File("");
        System.out.println(path.getAbsolutePath());
        //第二种
        System.out.println(System.getProperty("user.dir"));
        //第三种
        String path1 = ClassUtils.getDefaultClassLoader().getResource("").getPath();
        System.out.println(URLDecoder.decode(path1, "utf-8"));
        //第四种
        String path2 = ResourceUtils.getURL("classpath:").getPath();
        System.out.println(path2);
        //第五种
        ApplicationHome h = new ApplicationHome(getClass());
        File jarF = h.getSource();
        System.out.println(jarF.getParentFile().toString());

//linux和windows下通用
private String getJarFilePath() {
    ApplicationHome home = new ApplicationHome(getClass());
    File jarFile = home.getSource();
    return jarFile.getParentFile().toString();
}
