编程运行键盘命令

Question

我想在Java代码中运行以下主键命令：

keytool -v \
        -genkeypair \
        -dname "$SERVER_DN" \
        -keystore "$SERVER_DIR"/keystore.jks \
        -storepass "$SERVER_PW" \
        -keypass "$SERVER_PW" \
        -keyalg "EC" \
        -alias server \
        -validity 1825 \
        -deststoretype pkcs12 \
        -ext KU=digitalSignature,dataEncipherment,keyEncipherment,keyAgreement \
        -ext EKU=serverAuth \
        -ext SAN="$SERVER_SAN"

想知道以编程方式进行操作的最佳方法。有可能吗？

Answer 1

 String command = "keytool -v \
    -genkeypair \
    -dname "$SERVER_DN" \
    -keystore "$SERVER_DIR"/keystore.jks \
    -storepass "$SERVER_PW" \
    -keypass "$SERVER_PW" \
    -keyalg "EC" \
    -alias server \
    -validity 1825 \
    -deststoretype pkcs12 \
    -ext KU=digitalSignature,dataEncipherment,keyEncipherment,keyAgreement \
    -ext EKU=serverAuth \
    -ext SAN="$SERVER_SAN""

 ProcessBuilder pb = new ProcessBuilder("cmd.exe");
 Process process = pb.start();
 PrintWriter commandWriter = new PrintWriter(new OutputStreamWriter(new BufferedOutputStream(process.getOutputStream())));
 commandWriter.println(command);
 commandWriter.flush();

此外，您也可以从process.getErrorStream（）和process.getInputStream读取错误流或输入。
