2.1 Configure JAVA_HOME
2.1.1 Right click on My Computer--->Properties--->Advanced System Settings
2.1.2 Click Environment Variables
Create a new JAVA_HOME variable in the system variable
(You can also directly browse your JDK installation location, pay attention to the installation location of JDK, just select the entire folder directly)
2.2 Configure CLASSPATH
The same is true, create a new CLASSPATH variable in the system variable
Here you can directly copy my code and paste it (a pointer similar to the pointer in C language is used, if you change the JDK in the future, you can modify the address in JAVA_HOME)
.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;2.3 Configure the CATALINA_HOME variable
The path here selects the path you just installed Tomcat
2.4 Configure the PATH variable
Find the PATH variable in the system variables, click "Edit", "New", and add this code (the pointer of the pointer is also used)
%CATALINA_HOME%\lib;%CATALINA_HOME%\bin2.5 Set JAVA_HOME path in Tomcat
Open setclasspath.bat with Notepad in the bin directory under the directory where Tomcat is installed
Adding the path of JAVA_HOME around line 21 is actually the path of JDK

URIEncoding="UTF-8"

Change the output format to GBK around line 51
After the modification is complete, start Tomcat again and you will find that the console has output Simplified Chinese.
After configuring Tomcat, we try to create a new project in idea and run it

Just go to the next step
Just go to the next step
4.1.1 Select project path
4.2 Add web dependencies

The following interface will pop up
At this time, we saw a red exclamation mark below, and then eliminated it
4.3.3 Click Deployment next to Server to deploy
4.3.4 Then click the plus sign and select Artifact
At this point, you can see that the exclamation mark has disappeared, so that we have configured the path for accessing in the browser later (the path here can also be changed, because we will not change the default for the first time)
4.3.5 Click OK , the deployment is complete, and you can see a Tom cat coming out, and there is also a run button next door.
5 opens a new world
This inde.jsp is an interface that will be opened automatically after we successfully run Tomcat in the idea later
We enter hello world under the body tag
Finally click the run button in step 4.3.5
But after a while, we can see that the operation information in simplified Chinese has been output in our console!
After running successfully, the browser will automatically open : Hello World!
So far we have learned the operation from 0 to the successful configuration of Tomcat. If you have any questions, please leave a message in the comment area.
