创建maven工程

添加tomcat

这个tomcat应该都会，就不多说了

并且自己把webapp加进去 

引入maven依赖

<packaging>war</packaging>
    
    <dependencies>
        <!-- cas -->
        <dependency>
            <groupId>org.jasig.cas.client</groupId>
            <artifactId>cas-client-core</artifactId>
            <version>3.5.1</version>
        </dependency>
        <dependency>

            <artifactId>servlet-api</artifactId>
            <version>2.5</version>
            <scope>provided</scope>
        </dependency>
    </dependencies>

 配置webapp\web.xml

注意：ip和端口号要配置成 自己CAS服务器上的IP      和自己客户端(client)上的ip和端口号

在resource下创建applicaiton.properties

这个不知道有没有用，哈哈哈

cas.validation-type=CAS3

 创建index.jsp进行登录/退出测试

<%@ page language="java" contentType="text/html; charset=utf-8"
         pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>一东易买</title>
</head>
<body>
欢迎来到一东易买
<%=request.getRemoteUser()%>

    <!--这个是cas服务器上的ip和端口号-->
<a href="http://localhost:8080/cas/logout">退出登录1</a>

</body>
</html>

启动tomcat进行验证

验证成功！！
