Java keytool命令未从Process builder运行

Question

我试图运行从ProcesBuilder的JAVA的关键工具命令，但它失败与以下错误：

“非法选项：-genkeypairKey和证书管理工具命令：-certreq生成证书请求-changealias
更改条目的别名-删除删除条目-exportcert导出证书-genkeypair
生成密钥对-genseckey生成密钥-gencert从证书请求生成证书-importcert
导入证书或证书ain-importpass导入密码-importkeystore从另一个密钥库导入一个或所有条目-KeyPassword更改条目的密钥密码-列表列出密钥库中的条目-printcert
打印证书的内容-printcertreq打印证书请求的内容-printcrl
打印CRL文件的内容-StorePassword更改密钥库的存储密码“keytool-command_name-help”了解command_name的用法

下面是同样的代码片段：

public void testName() throws Exception {
    {
        String[] commands = { "keytool ", " -genkeypair  ", " -keyalg ", " RSA ", " -keysize ", " 2048 ",
                " -alias ", " rootkey ", " -dname ", "DNAME_INFORMATION", " -keystore ", " .keystore ",
                " -storetype ", " PKCS12 ", " -storepass ", " pass ", " -keypass ", " pass" };
        ProcessBuilder probuilder = new ProcessBuilder(commands);
        // You can set up your work directory
        probuilder.directory(new File(System.getenv("JAVA_HOME") + "\\bin"));

        Process process = probuilder.start();

        // Read out dir output
        InputStream is = process.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader br = new BufferedReader(isr);
        String line;
        final StringBuilder commandStr = new StringBuilder();
        for (final String command : commands) {
            commandStr.append(command);
            commandStr.append(" ");
        }
        System.out.printf("Output of running %s is:\n", commandStr.toString());
        is = process.getErrorStream();
        if (null != is) {
            isr = new InputStreamReader(is, Charsets.UTF_8);
            br = new BufferedReader(isr);
        }
        StringBuffer sbuffer = new StringBuffer();
        if (null != br) {
            while ((line = br.readLine()) != null) {
                sbuffer.append(line);
            }
        }
        // If sbuffer contains some value then error has occured.
        // Wait to get exit value
        try {
            int exitValue = process.waitFor();
            System.out.println("\n\nExit Value is " + exitValue);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

如果我们从%JAVA_HOME%/bin目录（即cmd）运行相同的命令，那么它将创建。没有任何错误的密钥库文件。

命令：keytool-genkeypair-keyalg RSA-keysize 2048-alias rootkey-dname“dname_信息”-keystore。密钥库-存储类型PKCS12-存储通行证-密钥通行证

请告知是否有人遇到过此类问题。

谢谢。

你必须去掉论点周围的空格。

String[] commands = { "keytool ", "-genkeypair", "-keyalg", "RSA", "-keysize", "2048",
    "-alias", "rootkey", "-dname", "DNAME_INFORMATION", "-keystore", ".keystore",
    "-storetype", "PKCS12", "-storepass", "pass", "-keypass", "pass" };

顺便说一句，您可以直接访问密钥库，请参阅密钥库类。
