我在下面获得证书例外。在创建自签名证书后如何检查CN？我很确定我使用了开发服务器的IP地址，但我不明白可能出现的问题。

编辑部分从这里开始：
感谢@ My-Name-Is，我做了以下事情：
keytool -printcert -v -file serverdev.cer
得到了这个结果：
Owner: CN=xx.x.x.xxx, OU=it, O=companyname, L=cityname, ST=provincename, C=ca
Issuer: CN=xx.x.x.xxx, OU=it, O=companyname, L=cityname, ST=provincename, C=ca
Serial number: somestringhere
Valid from: Fri Feb 28 16:11:14 EST 2014 until: Thu May 29 17:11:14 EDT 2014
Certificate fingerprints:
MD5: someotherstringhere
SHA1: andyetanotherstringhere
请注意，我确认CN xx.x.x.xxx与开发服务器的IP地址匹配。那么，究竟可能出现什么问题呢？
答案 0 :(得分：1)
您可以使用操作系统中的简单解决方案解决此问题，方法是将证书上的DNS映射到您实际访问的IP地址。例如，如果为DNS mydomain.com颁发证书并且您正在访问此IP地址10.10.10.0，则在此处找到的hosts文件中添加以下记录（如果您使用的是Windows）
C：\窗口\ system32 \驱动程序\等
添加此行
10.10.10.0 mydomain.com
然后更改您访问的URL以使用此域名mydomain.com而不是IP地址，现在Windows将使用您的IP地址10.10.10.0替换mydomain.com以获取所有请求。
