tomcat8安装https证书

1.进入网址https://myssl.com/cert_convert.html 将证书转成jks格式，并放到tomcat conf根目录下

2.打开tomcat server.xml 配置

　　将如下配置放开注释，并改成如下：

　　<Connector port="443" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="150" SSLEnabled="true"> 
        <SSLHostConfig> 
            <Certificate certificateKeystoreFile="conf\你的jks证书文件"  certificateKeystorePassword="证书密码" type="RSA" /> 
       </SSLHostConfig>
     </Connector>

　　注意将端口改为443，https默认端口443

3.目的是将 http 自动转换为 https

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="443" />

4.打开web.xml配置

<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>

将这些配置放在最后面，最后重启tomcat即可
