Tomcat 启动出现警告问题Setting property 'minSpar eThreads' to '25' did not find a matching property

tomcat启动报错:

具体解决方法如下：

server.xml中的配置HTTPS的那部分Connector代码

<Connector acceptCount="200"
port="${http.port}"
protocol="HTTP/1.1"   //要修改这行
executor="tomcatThreadPool"
enableLookups="false"
connectionTimeout="20000"
maxKeepAliveRequests="15"
minProcessors="20"
maxProcessors="200"
redirectPort="{https.port}"
disableUploadTimeout="true"/>

修改后：

<Connector acceptCount="200"
port="${http.port}"
protocol="org.apache.coyote.http11.Http11Protocol"  //protocol 协议要写全
executor="tomcatThreadPool"
enableLookups="false"
connectionTimeout="20000"
maxKeepAliveRequests="15"
minProcessors="20"
maxProcessors="200"
redirectPort="{https.port}"
disableUploadTimeout="true"/>

将protocol参数由"HTTP/1.1"改成"org.apache.coyote.http11.Http11Protocol"，重新启动Tomcat,就没问题了。
