CAS - Jump to the login page after logging out

Recently, the project is relatively large, there are many subsystems, and there is a need to use single sign-on, so I use cas serive

Integration steps:

You can download cas-server directly and run it.
The steps are roughly as follows:
1. Run the cas-server service2
. Let the cas-server authenticate through jdbc3
. Modify the login page
of the cas-server4. Integrate the business system with the cas-client

A concise tutorial on implementing SSO using CAS

The principle of single sign-on is to intercept the URL you set and jump to the CAS SERVER login page you specify. When you log in successfully, take TICKET and return to the URL you opened. Then you can have one vote in hand and unimpeded.

CAS official website

Corresponding github address:

Description: cas-server: Version 4.0.0 has been directly provided by the previous version 3.x 

However, after 4 and 5, the war package is not provided at the beginning, and you need to use the tools on the official website to make a war package; (maven and gradle) are supported, two tools

cas 5.x starts to use spring boot and it is completely different from before.

For the pit I encountered, both the cas client and the cas server were configured, but different systems still could not log in and log out at the same time. As a result, the reason for the error was:
