使用的是UCloud的免费证书:java
教程:web
https://docs.ucloud.cn/security/ussl/indexapache
购买证书的地址:tomcat
https://console.ucloud.cn/ussl/usslapp
根据教程,会有jks文件,及本身定义的密钥,后边是配置tomcat。url
首先把jks放入tomcat的conf目录。server
而后配置server.xmlxml
<Connector port="443" protocol="org.apache.coyote.http11.Http11Protocol" SSLEnabled="true" maxThreads="150" scheme="https" secure="true" keystoreFile="conf/jks文件" keystorePass="自定义的密钥" clientAuth="false" sslProtocol="TLS" />
注意,若是但愿访问http直接跳转https的话,须要在web.xml的</web-app>前添加;blog
<login-config> <auth-method>CLIENT-CERT</auth-method> <realm-name>Client Cert Users-only Area</realm-name> </login-config> <security-constraint> <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>
若是但愿既兼容http又兼容https,那么删除web.xml上边配置的,同时在server.xml添加80端口配置教程
<Connector port="80" connectionTimeout="30000" redirectPort="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" />
