Convert Http of external tomcat of Springboot LAN project to Https
First, you need the keytool tool provided with JDK to generate keys and certificates
Enter in CMD
Keytool -genkey -alias Tomcat -keyalg RSA -keystore/ Server Keystore to get one Keystore file
Enter keystore password:123456
Enter the new password again:123456

[no]: y
input <tomcat> Key password for
(If the password is the same as the keystore password, Press enter):
Enter the new password again:
Warning:
JKS The keystore uses a proprietary format. Recommended use "keytool -importkeystore -srckeystore C:\Users\Administrator\.keystore -destkeystore C:\Users\Administrator\.keystore -deststoretype pkcs12" Migrate to industry standard format PKCS12.
Open eclipse, start setting tomcat, and remove the checked Automatically publish when starting servers in Window → Preferences → Server → Launching
Then change the Server folder in the eclipse working directory, where there is a Server XML (remember to back up the original file first), and modify the content to
<?xml version="1.0" encoding="UTF-8"?>

Tomcat server XML must be configured with two connectors, one http and one https. If you configure Tomcat to start with eclipse or idea, you can only modify the port numbers of those two. The port priority is for the development tool, and the other data priority is to read the server of Tomcat XML, only the port will be overwritten. If you do not want to access http, set the server Delete the http connector in the XML (then set the configured http port in the Tomcat of eclipse to null, and http cannot be accessed. If you want to use http, keep it. If you don't need it, delete it. Moreover, ClientAuth is the key. If this is filled in as false, there is no difference between http and https. If you change it to true, you need a certificate.)
Then double-click tomcat in Servers. Before double clicking, remember to remove all the previously imported projects, and then select the second one from the Server Locations option. This is for me to test whether I can open the tomcat home page.
Finally, change the server XML, and then copy it to the server The contents of XML are copied in.
Then start the project. In case of an error, look carefully at the output content in the console. Most of the errors are caused by port occupation. Use CMD to find out what process occupies the port, For example, the command netstat -ano | findstr "8005" "tasklist | findstr" 3228 "taskkill /f /t /im javaw.exe, or directly change the port numbers in the two server.xml. I use 443 because it is convenient to fill in the port numbers when you do not need to enter the web address.
Such a project is successfully converted from http to https
