CAS based SSO single point client configuration

• 1、 initialization SpringBoot project
• 2、 Write code
  • 1、 Add configuration information
  • 2、 add to Controller
• 3、 Start the client service

be based on CAS Of SSO Single point client configuration

After creating the server , Then create the client , Test the server

1、 initialization SpringBoot project

When initializing , Check spring web service , It can also be built directly maven service

        <dependency>
            <groupId>net.unicon.cas</groupId>
            <artifactId>cas-client-autoconfig-support</artifactId>
            <version>2.3.0-GA</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

maven Friends whose foundation is not solid enough , Still recommended IDEA Bring your own spring Initial chemical tool , Create two projects , Namely web-client-01 and web-client-02

2、 Write code

stay SpringBoot Add on startup class @EnableCasClient Turn on CAS

Namely webClient01Application、webClient02Application

To save space , I will only list an example of the following configuration , Read the text carefully

1、 Add configuration information

server:
  port: 9093
cas:
  server-login-url: http://localhost:9101/cas/login # CAS  Service login address 
  server-url-prefix: http://localhost:9101/cas      # CAS  service 
  client-host-url: http://localhost:9093      #  The local service 
  validation-type: cas3               #  Encryption type 

The two services are used separately 9092、9093 port ,CAS Service login address 、CAS The service and encryption types are consistent , That is, the port address we configured before , Jump address ：, Only the local service port should be flexibly configured

2、 add to Controller

Both services add this controller

import org.jasig.cas.client.authentication.AttributePrincipal;
import org.jasig.cas.client.validation.Assertion;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpSession;

import static org.jasig.cas.client.util.AbstractCasFilter.CONST_CAS_ASSERTION;

@RestController
public class Controller {

    @RequestMapping("/sso-test1")
    public String test1(HttpSession session){
        Assertion assertion = (Assertion)session.getAttribute(CONST_CAS_ASSERTION);
        AttributePrincipal principal = assertion.getPrincipal();
        String loginName = principal.getName();
        return "sso-test1, Current login account "+loginName;
    }
}

It's all set up here

3、 Start the client service

Access address ：

http://localhost:9092/sso-test1

You will find that the page directly jumps to the login page

We fill in the configured server user name and password

Click to log in

Let's test the single point effect , visit

http://localhost:9093/sso-test2

It is as expected , Single sign on simulation succeeded ！ Finally, let's show Code structure of client

The client code is too simple , I won't upload it GitHub 了 , If you want a little partner, you can contact Ben Up. Finally, I wish you all find your favorite job

Finally, let's pay attention
