cas基础--客户端集成

Updated on Oct 16, 2023 with 0 views and 0 comments

一、引入依赖

<cas-client.version>2.3.0-GA</cas-client.version>

            <dependency>
                <groupId>net.unicon.cas</groupId>
                <artifactId>cas-client-autoconfig-support</artifactId>
                <version>${cas-client.version}</version>
            </dependency>

引入spring-security-cas

        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-cas</artifactId>
        </dependency>

spring-security-cas中包含spring security依赖和cas-client-core依赖

如果不想用spring security想用shiro，可以只引入cas-client-core依赖，再引入需要用到的shiro依赖

    <dependency>
      <groupId>org.jasig.cas.client</groupId>
      <artifactId>cas-client-core</artifactId>
      <scope>compile</scope>
      <version>3.6.1</version>
    </dependency>

二、配置cas

添加如下配置，设置cas地址，cas登录地址，客户端的访问路径，认证类型

cas:
  server-url-prefix: http://localhost:8022/cas
  server-login-url: http://localhost:8022/cas/login
  client-host-url: http://1.long1.com:8081
  validation-type: cas3

spring boot启动类添加注解

@EnableCasClient

三、接口代码

新建controller

package com.xdny.sso.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@RestController
public class IndexController {


    @RequestMapping("/index")
    public ModelAndView root(){
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("index");
        return modelAndView;
    }


    @RequestMapping("/logout")
    public void logout (HttpServletResponse response) throws IOException {
        // 清理系统session
        response.sendRedirect("http://localhost:8022/cas/logout");
    }
}

四、前端页面

这里使用thymeleaf做测试，引入thymeleaf以及web依赖依赖

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


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

页面代码

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
  <font th:text="${session._const_cas_assertion_.principal.name}"></font><br>
<a href="http://2.long2.com:8082" target="_blank">服务2</a>
<a href="http://3.long3.com:8083" target="_blank">服务3</a>
<a href="/logout">安全退出</a>
</body>
</html>

启动代码后就会跳到我们cas的登录页面了
