我在通过java代码访问https网址时遇到异常。当我尝试访问时，我得到以下异常：

我尝试使用以下命令生成SSL证书：

./jdk1.8/bin/keytool -genkey -keystore /srv/jakarta/.keystore -alias ALIAS \
    -keyalg RSA -keysize 4096 -validity 720
Enter keystore password: # well, enter something
Re-enter new password: # same as above
What is your first and last name?
  [Unknown]:  localhost # !!! IMPORTANT this is the domain name, NOT YOUR name
What is the name of your organizational unit?
  [Unknown]:  # enter something or leave empty
What is the name of your organization?
  [Unknown]:  # enter something or leave empty
What is the name of your City or Locality?
  [Unknown]:  # enter something or leave empty
What is the name of your State or Province?
  [Unknown]:  # enter something or leave empty
What is the two-letter country code for this unit?
  [Unknown]:  # enter something or leave empty
Is CN=example com, OU=Foo, O=Bar, L=City, ST=AA, C=FB correct?
  [no]:  yes
Enter key password for <lea-prod>
    (RETURN if same as keystore password): # Press RETURN

并使用以下tomcat / server.xml配置：

 <Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
       maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
       clientAuth="false" sslProtocol="TLS"
       keyAlias="ALIAS" keystoreFile="/srv/jakarta/.keystore"
       keystorePass="PW from step 1" />

然而，它仍然无法正常工作，我面临同样的错误。

有什么办法可以解决这个问题吗？感谢

Answer 1

嗯，这正是错误消息的结果。您的证书是使用通用名称example.com颁发的。但是，您在地址栏中输入了localhost作为服务器的名称。显然，这两个不匹配。您还应将证书公用名（CN）更改为localhost，即重新生成证书，但使用正确的名称localhost。

在下一步中，您需要将该证书导入浏览器的证书库。但这是另一个话题。在更正证书的通用名称后，该例外应该消失。

Answer 2

我相信您正在尝试访问HTTPS协议上托管的服务。在这种情况下，您需要获取网站/服务的证书并将其添加到您的Java密钥库。这是您应该在生产代码中使用证书的方式

或者，您可以覆盖HostNameVerifier类以抑制任何错误，并在Java SSL上下文中将其设置为忽略任何错误。理想情况下，用户可以抑制检入测试代码或SSL证书不可用。

localhost上的SSL证书无法正常工作
