导入证书后出现Java Keytool错误，“keytool error：java.io.FileNotFoundException&访问被拒绝“ [英] Java Keytool error after importing certificate , "keytool error: java.io.FileNotFoundException & Access Denied"

问题描述

我正在尝试通过HTTPS连接Java Web API;然而，抛出异常：

I'm trying to connect a Java Web API via HTTPS; however, an exception is thrown:

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException

我按照以下步骤从网上keytool& SSL证书教程：

I followed these steps which I learned from online keytool & SSL cert tutorials:

1. 我将HTTPS URL复制到浏览器中，下载了SSL证书&使用Internet Explorer将它们安装在浏览器中。

1. I copied the HTTPS URL into the browser, downloaded the SSL certificates & Installed them in the browser using Internet Explorer.

将证书导出到计算机上的路径，证书保存为 .cer

Exported the certificates to a path on my computer, the certificates were saved as .cer

使用了keytool的导入选项。执行下面的命令没有任何错误。

Used the keytool's import option. The command below executed without any errors.

keytool -import -alias downloadedCertAlias -keystore C:\path\to\my\keystore\cacerts.file -file C:\path\of\exportedCert.cer

我在命令提示符下提示输入密码，然后我输入了密码。

I was prompted for a password at the command prompt, which I entered then I was authenticated.

cmd 窗口打印了一些证书数据&签名和我被提示问题：

The cmd window printed some certificate data & signatures and I was prompted with the question:

信任此证书？

Trust this certificate?

我回答是。

显示的cmd提示

证书已添加到密钥库

Certificate was added to keystore

但是在该消息之后，显示了另一个异常：

However after that message, another exception was displayed:

keytool error: java.io.FileNotFoundException: C:\Program files\...\cacerts <Access Denied>

最后，当我检查密钥库时，SSL没有添加证书，我的应用程序给出了我在尝试连接时得到的相同例外：

Finally when I checked the keystore , the SSL certificate was not added and my application gives the same exception I was getting earlier when trying to connect:

(javax.net.ssl.SSLHandshakeException:sun.security.validator.ValidatorException)

推荐答案

如果您未在管理员模式下运行命令提示符，则可能会发生这种情况。
如果你使用的是Windows 7，你可以去运行，键入cmd然后按Ctrl + Shift + enter。这将以管理员模式打开命令提示符。如果没有，您还可以开始 - >所有程序 - >附件 - >右键单击命令提示符，然后单击以管理员身份运行。

This could happen if you are not running the command prompt in administrator mode. If you are using windows 7, you can go to run, type cmd and hit Ctrl+Shift+enter. This will open the command prompt in administrator mode. If not, you can also go to start -> all programs -> accessories -> right click command prompt and click 'run as administrator'.
