tomcat 支持单向https

先做证书.做好之后

修改server.xml

 <Connector port="80"   
				connectionTimeout="20000" 
				protocol="org.apache.coyote.http11.Http11NioProtocol" 
				URIEncoding="UTF-8" acceptCount="1100"
				disableUploadTimeout="true"
				 maxSpareThreads="500" maxThreads="1000" minSpareThreads="250"
               redirectPort="443" />

  <Connector port="8009" protocol="AJP/1.3" redirectPort="443" />


 <Connector SSLEnabled="true" clientAuth="false" keystoreFile="证书文件" keystorePass="证书密码" maxThreads="150" port="443" protocol="org.apache.coyote.http11.Http11NioProtocol" scheme="https" secure="true" sslProtocol="TLS"/> 

这个时候应用还不是强制走https ,也就是说 https 和 http都能访问

修改应用的web.xml 根据你的实际情况来

<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>
