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

 

环境要求

  • JDK 8+
  • CAS 5.2
  • tomcat 8+

步骤

一、搭建CAS服务器  –> 

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:

  • 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
<?xml version="1.0" encoding="UTF-8"?>

            </plugin>
        </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">

    <!-- 自动扫描该包,使SpringMVC认为包下用了@controller注解的类是控制器 -->
    <context:component-scan base-package="com.oumuv"/>
    <!-- 扩充了注解驱动,可以将请求参数绑定到控制器参数 -->
    <mvc:annotation-driven/>

    <!-- 访问静态资源 -->
    <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是服务端的地址,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进入CAS-clientA主页:

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

输入账号和密码完成登录后跳转到hello页面:

到此项目搭建完成
