Tomcat 报错 The APR based Apache Tomcat Native library which allows optimal performance in production environmen

This problem appeared when I reinstalled tomcat and myeclipse once. To be honest, this problem was a big problem, but fortunately it was solved. At first, I looked for various solutions. Finally, I commented a line in server.xml directly to solve this error. Perfect, but I still post it to analyze my results

Comment out this line and the problem will not occur <!-- <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />-->

<Server port="8005" shutdown="SHUTDOWN">

  <!--APR library loader. Documentation at /docs/apr.html -->
 <!-- <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" /> --> This is the line, you can find this line in server.xml
  <!--Initialize Jasper prior to webapps are loaded. Documentation at /docs/jasper-howto.html -->
  <Listener className="org.apache.catalina.core.JasperListener" />
  <!-- Prevent memory leaks due to use of particular java/javax APIs-->
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
  <!-- JMX Support for the Tomcat server. Documentation at /docs/non-existent.html -->
  <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />

In the future, I will slowly think that I can't solve this problem now, but I don't report an error.
