cas-server 版本：4.0.0
tomcat 7或者8
jdk 1.7或1.8
本次搭建环境，tomcat8、jdk1.7
创建证书
keytool -genkey -alias cas -keyalg RSA -keystore E:/keys/casKey
注意：创建证书时，填写"您的名字与姓氏是什么"为后期用到的域名。域名不可是ip或者localhost
导出证书
keytool -export -file E:/keys/cas.crt -alias cas -keystore E:/keys/caskey
将证书导入到jdk
keytool -import -keystore D:/jdk/jre/lib/security/cacerts -file E:/keys/cas.crt -alias cas
注意：导入证书的口令默认为changeit，并不是之前创建证书的口令
特别注意：如果安装有独立的jre，将证书导入到独立的jre中，否则通过应用访问时会报一个错误
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
参考地址：https://blog.csdn.net/aosica321/article/details/54945553
查看导入jdk中的证书
keytool -list -keystore "D:/jdk/jre/lib/security/cacerts" | findstr /i cas
删除jdk中的证书
keytool -delete -alias cas -keystore "D:/jdk/jre/lib/security/cacerts" -storepass changeit
修改tomcat/server.xml文件
修改前：
<Connector port="8040" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8444"/>
修改后：
<Connector port="8040" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8444" SSLEnabled="true" maxThreads="150"
scheme="https" ecure="true" clientAuth="false" sslProtocol="TLS"
keystoreFile="E:\keys\casKey" keystorePass="创建证书时录入的口令" />
修改hosts文件
127.0.0.1 创建证书时写的姓名（域名）
修改cas服务中的cas/WEB-INF/deployerConfigContext.xml文件
