最近配置tomcat证书遇到这么一个问题，简单的分享下：
报错信息如下：

keytool -keystore m.jks -list
Keystore type: JKS Keystore provider: SUN Your keystore contains 1 entry server（别名）, Dec 6, 2016, PrivateKeyEntry（条目类型）, Certificate fingerprint (SHA1): AE:49:98:23:0F:5E:28:58:01:6C:6D:E0:65:12:B5:70:75:64:EA:38
在tomcat server.xml 文件配置
<Connector port="443" protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="150" scheme="https" secure="true"
keystoreFile="/usr/local/tomcat/conf/my.jks" keystorePass="password" keyAlias="server"
clientAuth="false" sslProtocol="TLS" />
重启tomcat，浏览器访问
