Question

java中调用cmd命令

cd /d E:/tomcat/bin
service.bat install 这是在cmd下将tomcat添加得到服务里
但是我现在想在java文件中执行结果 怎么写

Answer 1

可以通过Runtime 的exec方法来进行执行。举例：
public class Test {
public static void main(String[] args) {
Runtime r=Runtime.getRuntime();
Process p=null;
try{
String s="DOT的路径\\dot.exe c:\\user\\Administrator\\test.txt -Tpng -o result.png";
p=r.exec(s);
}catch(Exception e){
System.out.println("错误:"+e.getMessage());
e.printStackTrace();
}
}
}

Answer 2

Runtime.getRuntime().exec("cmd命令");

Runtime.getRuntime().exec("E:/tomcat/bin/service.bat install");

追问

The tomcat.exe was not found...
The CATALINA_HOME environment variable is not defined correctly.
This environment variable is needed to run this program

追答

Runtime.getRuntime().exec("cd /d E:/tomcat/bin");

Runtime.getRuntime().exec("service.bat install");

试试或者 自己写个bat
里面
cd /d E:/tomcat/bin
service.bat install
然后在执行你写的这个bat

Answer 3

Runtime.getRuntime().exec("cmd /c E:/tomcat/bin/service.bat install");

Answer 4

Runtime.getRuntime().exec("cmd /c service.bat install", null, "e:/tomcat/bin");

Answer 5

Runtime.getRuntime().exec(command);
