Java移动应用程序到启动文件夹

Question

public class info {
    
    public static String getautostart() {
        return System.getProperty("java.io.tmpdir").replace("Local\\Temp\\", "Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Startup");
    }
    
    public static String gettemp() {
        String property = "java.io.tmpdir";
        String tempDir = System.getProperty(property);
        return tempDir;
    }
    
    public static String getrunningdir() {
        String runningdir = ProjectGav.class.getProtectionDomain().getCodeSource().getLocation().getPath();
        return runningdir;
    }
    
}

    System.out.println(info.getautostart() + "\\asdf.jar");
    System.out.println(info.getrunningdir());
    Files.move(info.getrunningdir(), info.getautostart() + "\\asdf.jar");

文件。move不起作用。

假设您要将jar从当前目录移动到autostart文件夹。您已经有了以下方法：

// nothing to change here - it seems to work just fine
public static String getautostart() {
    return System.getProperty("java.io.tmpdir").replace("Local\\Temp\\", "Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Startup");
}

// this one got confused with the '/' and '\' so I changed it
public static String getrunningdir() {
     //you need to import java.nio.file.Paths for that.
    String runningdir = Paths.get(".").toAbsolutePath().normalize().toString(); // it simulates the creation of a file in the current directory and returns the path for that file
    return runningdir;
}

现在移动文件需要路径而不是字符串，因此您需要为每个字符串创建一个路径实例：

 Path autostartPath = Paths.get(getautostart());
 Path currentPath = Paths.get(getrunningdir());

如果要指向路径中的文件（如.jar文件），可以这样做：

currentPath.resolve("myProgram.jar"); // The paths end with a `/` so you don't need to add it here

Files.move(currentPath.resolve("myProgram.jar"), autostartPath.resolve("myProgram.jar"));
