java执行shell并获取shell输出日志
获取shell输出日志需要java使用两个线程分别接受shell的标准输入流和错误流并打印出来
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.nio.charset.Charset;
public class ShellLogRunTest {
public static void main(String[] args) throws Exception, SecurityException {
Process p = null;
Runtime rt = Runtime.getRuntime();
String command = "cmd /c java -version";
command = "cmd /c ping 127.0.0.1 -n 3";
if (args != null && args.length > 0 && args[0] != null && args[0].trim().length() > 0) {
command = args[0];
}
try {
p = rt.exec(command, null, null);
// 获取进程的标准输入流
final InputStream is1 = p.getInputStream();
// 获取进城的错误流
final InputStream is2 = p.getErrorStream();
// 启动两个线程，一个线程负责读标准输出流，另一个负责读标准错误流
new Thread() {
public void run() {
BufferedReader br1 = new BufferedReader(new InputStreamReader(is1, Charset.forName("gb2312"))); // 这里要注意shell返回的类型,windows和linux可能不同
try {
String line1 = null;
while ((line1 = br1.readLine()) != null) {
if (line1 != null) {
System.out.println(line1);
}
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is1.close();
System.out.println("is1线程关闭");
} catch (IOException e) {
e.printStackTrace();
}
}
}
}.start();
new Thread() {
public void run() {
BufferedReader br2 = new BufferedReader(new InputStreamReader(is2, Charset.forName("gb2312")));
try {
String line2 = null;
while ((line2 = br2.readLine()) != null) {
if (line2 != null) {
System.out.println(line2);
}
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is2.close();
System.out.println("is2线程关闭");
} catch (IOException e) {
e.printStackTrace();
}
}
}
}.start();
p.waitFor();
p.destroy();
System.out.println("进程结束");
} catch (Exception e) {
try {
p.getErrorStream().close();
p.getInputStream().close();
p.getOutputStream().close();
} catch (Exception ee) {
ee.printStackTrace();
}
}
}
}
