SpringCloud Alibaba Sentinel 实现熔断功能

Tomcat多证书多域名必须是Tomcat 8.5以上版本

配置server.xml

      <Realm className="org.apache.catalina.realm.LockOutRealm">

        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"

      <Host name="domain1.cn"  appBase="webapps"

				<Context path="" docBase="d:/www/project1" reloadable="true" crossContext="true" ></Context> 
      </Host>
		

    </Engine>
  </Service>
</Server>

关键点说明:

1.defaultSSLHostConfigName 属性是必须，不设置默认配置会报错.

	<Connector
       protocol="org.apache.coyote.http11.Http11NioProtocol" 
           port="443"  SSLEnabled="true" defaultSSLHostConfigName="domain1.cn"
		   connectionTimeout="8000">

2.表示开启多域名支持

     <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />

3.Alias是多域名别名配置，这是同一个项目多个域名的配置。

<Host name="domain1.cn"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
		 <Alias>domain1.cn</Alias>
		<Alias>domain2.cn</Alias>
				<Context path="" docBase="d:/www/project1" reloadable="true" crossContext="true" ></Context> 
      </Host>

如果是多个项目多个域名配置多个<Host>节点即可。

<Host name="domain1.cn"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
				<Context path="" docBase="d:/www/project1" reloadable="true" crossContext="true" ></Context> 
      </Host>
<Host name="domain2.cn"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
				<Context path="" docBase="d:/www/project2" reloadable="true" crossContext="true" ></Context> 
      </Host>
