CAS（三）基于SpringMVC搭建CAS-client，SpringMVC搭建CAS客户端

梦里梦外; 2022-04-15 03:46 819阅读 0赞

# 环境要求 #

*  JDK 8+
 *  CAS 5.2
 *  tomcat 8+

# 步骤 #

## 一、搭建CAS服务器  --> [CAS（一）搭建CAS - server服务器][CAS_CAS - server] ##

## 二、配置hosts，加入如下配置 ##

127.0.0.1      cas.server.com
    127.0.0.1      cas.client1.com

## 三、搭建SpringMVC项目 ##

项目名为cas-clientA，项目结构如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L291bXV2_size_16_color_FFFFFF_t_70][]

*  包含三个页面：主页--index.jsp（无需登录），hello页面--hello.jsp（需要登录），退出成功提示页--logoutsuccess.jsp（无需登录）

*  pom.xml文件配置如下

            </plugins>
    
        </build>
    </project>

*  applicationContext.xml主要配置一下jsp解析器，配置如下：

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:context="http://www.springframework.org/schema/context"
           xmlns:mvc="http://www.springframework.org/schema/mvc"
           xsi:schemaLocation="http://www.springframework.org/schema/beans
                            http://www.springframework.org/schema/beans/spring-beans-4.0.xsd    
                            http://www.springframework.org/schema/context    
                            http://www.springframework.org/schema/context/spring-context-4.0.xsd    
                            http://www.springframework.org/schema/mvc    
                            http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
    
        
        <context:component-scan base-package="com.oumuv"/>
        
        <mvc:annotation-driven/>
    
        
        <mvc:default-servlet-handler/>
    
        <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/"/>
            <property name="suffix" value=".jsp"/>
            <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        </bean>
    
    </beans>

*  web.xml配置是重点，cas服务器和客户端的关联需要在此配置：

<?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </servlet-mapping>
    </web-app>

其中[http://cas.server.com:8443][http_cas.server.com_8443]是服务端的地址，[http://cas.client1.com:9001][http_cas.client1.com_9001]是客户端地址

*  CASController.java有两个业务如下：

/**
         * 主页
         * @param map
         * @return
         */
        @RequestMapping("index")
        public String index(ModelMap map) {
            map.addAttribute("name", "clien A");
            return "index";
        }
    
        /**
         * hello
         * @return
         */
        @RequestMapping("hello")
        public String hello() {
            return "hello";
        }

## 四、启动项目、测试 ##

依次启动CAS-server服务端、CAS-clientA客户端

访问[http://cas.client1.com:9001/index][http_cas.client1.com_9001_index]进入CAS-clientA主页：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L291bXV2_size_16_color_FFFFFF_t_70 1][]

点击client A（[http://cas.client1.com:9001/hello][http_cas.client1.com_9001_hello]），会跳转到cas登录认证页面：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L291bXV2_size_16_color_FFFFFF_t_70 2][]

输入账号和密码完成登录后跳转到hello页面：
