Runtime.getRuntime()。exec(“path to file”)运行,但程序行为很奇怪

标签: java exe

我正在为许多程序制作基于文本的启动器。我正在使用 Runtime.getRuntime().exec("path//to//file.exe"))方法。

程序将运行,它始终会运行,但有些行为奇怪或无法找到存在的关键.dll文件。其他人在运行时弄乱了文字。正如你所看到的,这些都是复杂的游戏并使用了许多我不理解的引擎。谢谢!

死亡空间3:屏幕是黑色的,但游戏仍在运行。只有显示似乎无法正常工作

MW3:TeknoMW3.exe无法找到teknomw3.dll,即使它们位于同一个文件夹中(正常启动它也可以正常运行)。

无尽的空间:文字显示奇怪。退出是%getuserexit%或类似于文本应该和通常显示的每个空间的内容。仅在主菜单上出现。

Splinter Cell Blaclist:Dir是正确的,无法找到指定的文件。我会在那个问题上工作。

生化奇兵1:直接崩溃(可能是由于.dll问题再次出现,我实际上并不知道)

生化奇兵2:永远不要跑。文件已执行但未运行。

程序很可能对其执行上下文有所期待。

从您的示例中,可能每个程序都在您运行程序的相同上下文/执行位置内启动,这意味着它们无法找到所需的库或资源。

不要直接使用Runtime#exec,而是尝试使用ProcessBuilder。这将允许您更改流程的执行位置。

例如......

String cmd = getDir();
File cmdFile = new File(cmd);
// Maybe check that the cmdFile.exists...;)
File parentFile = cmdFile.getParentFile();

ProcessBuilder pb = new ProcessBuilder(cmd);
pb.directory(parentFile);
pb.redirectError();

Process p = pb.start();

建议您阅读流程的InputStream,因为某些流程会因为某些流程而感到沮丧;)

InputStream is = p.getInputStream();
// This simple reads the contents from the InputStream and discards it
// You could change it to actually dump the output if wanted ;)
while (is.read() != -1);

int exitValue = p.waitFor();
