Detailed explanation of the principle of creating tomcat in Eclipse

When creating a tomcat server on a local eclipse,

A copy of the configuration file in the conf file in the tomca installation directory will be copied to this tomcatserver directory

This tomcatserver directory is in the workspaces path, the same path as other projects

The files are as follows. These configuration files are the startup parameters for starting the tomcat call

Startup parameters when starting tomcat

-Dcatalina.base="D:\Source Code\SVN2013\.metadata\.plugins\org.eclipse.wst.server.core\tmp3" -Dcatalina.home="F:\Apache\apache-tomcat-8.5.34" -Dwtp.deploy="D:\Source Code\SVN2013\.metadata\.plugins\org.eclipse.wst.server.core\tmp3\wtpwebapps" -Djava.endorsed.dirs="F:\Apache\apache-tomcat-8.5.34\endorsed"

-Dcatalina.base

-D indicates a parameter, catalina.base indicates the parameter name, and the string after = indicates the value corresponding to the parameter.

Use the System.getProperty("catalina.base") method to get the corresponding value.

When starting here,

catalina.base, which indicates the working directory of Tomcat, or catalina.base refers to an instance of Tomcat.

catalina.home indicates the installation directory of Tomcat, that is, the directory containing the bin file.

wtp.deploy is the target path for project deployment, or the target path for the project to be copied after compilation. This directory is equivalent to the root directory of the address http://localhost:8080/ when accessing tomcat.
