Java.lang.NoSuchMethodError:org.apache.catalina.connector.Connector.setProtocol (ljava/lang/string;)

1. Before the project code changed a computer, and then ran back to the time of the inexplicable error, probably have some of the following error message

Again, some of the following errors:

The server log for details.

2. Solution:

① is searching for the keyword "to prevent a memory leak, the JDBC Driver has the been forcibly unregistered", find the solution given two points, one is to copy JDBC Driver to Tomcat Lib directory, the second is the annotation of the Tomcat configuration file Server.xml (<listener classname=) Org.apache.catalina.core.JreMemoryLeakPreventionListener "/>", so that after the operation or not.

② search for the keyword "java.lang.NoSuchMethodError:org.apache.catalina.connector.Connector.setProtocol (ljava/lang/string;) V", No solution was found.

After ③ changed the new computer, my development tools, idea, MAVEN, Tomcat, JDK are all the latest downloads, The latest version of Tomcat (apache-tomcat-9.0.1), my colleague suggested I change to a tomcat, I'd better replace apache-tomcat-8.5.23.
