如何将文件编写器的路径设置为使用它的 jar 的位置？

Question

所以我最近从服务启动 jar 文件，而不是首先转到相关目录的脚本。有没有办法确保使用 jar 文件的路径而不是服务启动的路径？在应用程序内部，我使用下面的代码来获取正确的路径。

   try {
        Path p = Path.of(getClass().getProtectionDomain().getCodeSource().getLocation().toURI());

        workPath = p.getParent().toString();

        if( workPath.matches(".*[lib]")) { // Meaning used as a lib
            workPath = Path.of(workPath).getParent().toString();
        }
        settingsFile = Path.of(workPath, "settings.xml");
    } catch (URISyntaxException e) {
        Logger.error(e);
    }

将您的工作路径存储为系统属性:

try {
    Path p = Path.of(getClass().getProtectionDomain().getCodeSource().getLocation().toURI());

    workPath = p.getParent().toString();
    if(workPath.matches(".*[lib]")) { // Meaning used as a lib
        workPath = Path.of(workPath).getParent().toString();
    }

    System.setProperty("tinylog.directory", workPath); // Set work path as system property
    settingsFile = Path.of(workPath, "settings.xml");
} catch (URISyntaxException e) {
    Logger.error(e);
}

在tinylog.properties中使用系统属性:

writer        = file
writer.file   = #{tinylog.directory}/log.txt
writer.format = {date: HH:mm:ss.SSS} {level}: {message}
