我正在尝试安装 apche tomcat。需要设置环境变量，如何设置环境变量？
我尝试使用 ProcessBuilder 但它不起作用:
ProcessBuilder pb = new ProcessBuilder("CMD.exe", "/C", "SET"); // SET prints out the environment variables
pb.redirectErrorStream(true);
Map<String,String> env = pb.environment();
String path = env.get("CATALINA_HOME") + apachePath;
env.put("CATALINA_HOME", path);
Process process = null;
try {
process = pb.start();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
最佳答案
例子在这里:
import java.io.*;
import java.util.*;
public class Test
{
public static void main(String[] args) throws Exception
{
ProcessBuilder pb = new ProcessBuilder("CMD.exe", "/C", "SET"); // SET prints out the environment variables
pb.redirectErrorStream(true);
Map<String,String> env = pb.environment();
String path = env.get("Path") + ";C:\\naved\\bin";
env.put("Path", path);
Process process = pb.start();
BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));
String line;
while ((line = in.readLine()) != null)
{
System.out.println(line);
}
}
}
