tomcat支持两个ssl链接的方法：
打开server.xml配置，代码如下：
maxThreads=”150″ minSpareThreads=”25″ maxSpareThreads=”75″
enableLookups=”false” redirectPort=”443″ acceptCount=”100″
connectionTimeout=”20000″ disableUploadTimeout=”true” />
maxThreads=”150″ SSLEnabled=”true” defaultSSLHostConfigName=”www.test.a.com”>
certificateKeystoreType=”PKCS12″ />
certificateKeystoreType=”PKCS12″ />
resourceName=”UserDatabase”/>
unpackWARs=”true” autoDeploy=”true”>
www.test.a.com
www.test.b.com
prefix=”localhost_access_log” suffix=”.txt”
pattern=”%h %l %u %t “%r” %s %b” />
