我基本上有一个程序，它使用 apache poi 将记录从一个 excel 文件过滤到另一个 excel 文件。我的程序在使用 netbeans 运行时运行良好。但是，在进行清理和构建并双击 dist 文件夹中的 .jar 文件后，它运行了很长时间（太长了！）并给了我以下错误（我是通过从命令提示符运行程序得到的）。

有什么解决办法吗？在清理和构建之前，我已经在 netbeans 中将堆大小增加到 -Xms1500m。

'-Xms1500m' 标志是运行时标志，而不是编译时标志。您已在 Netbeans 中设置它，因此只有在您通过 Netbeans 运行时它才会获得该标志。

当您在 Netbeans 之外运行程序时，您需要像这样运行它：

java -Xms1500m -jar [你的程序在这里]。
