在我的eclipse项目中,我正在尝试运行系统命令,我已经用bash收集它们并将它放在我的项目文件夹中。
java代码部分是:
public static int exportDBMainData(String DBName, String UserName,
String Password, String FilePath) {
// First
String executeCmd = GraphEditor.class
.getResource("/src/sau/se/editor/recover/semapExport.bat")
+ UserName + " " + Password + " " + DBName + " " + FilePath;
Process runtimeProcess = null;
try {
runtimeProcess = Runtime.getRuntime().exec(executeCmd);
} catch (IOException e1) {
e1.printStackTrace();
}
int processComplete1 = -1;
try {
processComplete1 = runtimeProcess.waitFor();
} catch (InterruptedException e1) {
e1.printStackTrace();
}
return processComplete1;
}
当我运行应用程序时,我收到了错误:
java.io.IOException: Cannot run program "nullroot": CreateProcess error=2, The system cannot find the file specified
at java.lang.ProcessBuilder.start(Unknown Source)
at java.lang.Runtime.exec(Unknown Source)
at java.lang.Runtime.exec(Unknown Source)
at java.lang.Runtime.exec(Unknown Source)
我做错了什么?
更新 我部分修复了问题,现在我得到了:
java.io.IOException: Cannot run program "file:/F:/SEMAP_PROJECT/PHASE_1/ECLIPSE_KEPLER/Workspace/SeMap_Recover1.0/bin/sau/se/editor/recover/semapExport.bat": CreateProcess error=2, The system cannot find the file specified
答案 0 :(得分:0)
使用Runtime.exec,您不必执行shell命令行,而是执行真正的可执行文件,可选地使用String [] cmdArray String的参数。 所以你不能逐行执行bat,但你可以直接用run exec执行它:
Runtime.getRuntime().exec(new String[]{
"c:\\program files\\...\\semapExport.bat"
,UserName, Password,DBName,FilePath
});
当然,bat文件必须是真实文件,而不是jar中的资源。

我应该通过一个程序调用脚本的正确答案,它不能调用自己,所以我修复了它,它已经工作了:
String executeCmd = "cmd /c start "
+ DBUtils.class
.getResource("/sau/se/editor/recover/semapExport.bat")
+ " " + UserName + " " + Password + " " + DBName + " "
+ FilePath;
