主要是对 tomcat 的配置文件进行配置，位置在 apache-tomcat-9/conf 文件夹下
SSL证书可以上阿里云申请免费的。
首先修改 server.xml
<Connector port="80" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="443" />
<Connector port="443"
protocol="HTTP/1.1"
SSLEnabled="true"
scheme="https"
secure="true"
keystoreFile="/u01/tomcat/apache-tomcat-9.0.48/cert/xxxxxxxxx.pfx"
keystoreType="PKCS12"
keystorePass="xxxxxxxx"
clientAuth="false"
SSLProtocol="TLSv1+TLSv1.1+TLSv1.2"
ciphers="TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA256"/>
然后修改 web.xml
<login-config>
<!-- Authorization setting for SSL -->
<auth-method>CLIENT-CERT</auth-method>
<realm-name>Client Cert Users-only Area</realm-name>
</login-config>
<security-constraint>
<!-- Authorization setting for SSL -->
<web-resource-collection >
<web-resource-name >SSL</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
