Commons exec 提供了一个 PumpStreamHandler,它将标准输出重定向到 Java 进程的标准输出。如何将命令的输出捕获到字符串中?
他就是我找到的:
import java.io.ByteArrayOutputStream;
import org.apache.commons.exec.CommandLine;
import org.apache.commons.exec.DefaultExecutor;
import org.apache.commons.exec.Executor;
import org.apache.commons.exec.PumpStreamHandler;
public String execToString(String command) throws Exception {
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
CommandLine commandline = CommandLine.parse(command);
DefaultExecutor exec = new DefaultExecutor();
PumpStreamHandler streamHandler = new PumpStreamHandler(outputStream);
exec.setStreamHandler(streamHandler);
exec.execute(commandline);
return(outputStream.toString());
}
