CAS（三）基於SpringMVC搭建CAS-client，SpringMVC搭建CAS客戶端
阿新 • • 發佈：2018-11-22
環境要求
- JDK 8+
- CAS 5.2
- tomcat 8+
步驟
一、搭建CAS伺服器 --> CAS（一）搭建CAS - server伺服器
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專案
專案名為cas-clientA，專案結構如下：
- 包含三個頁面：主頁--index.jsp（無需登入），hello頁面--hello.jsp（需要登入），退出成功提示頁--logoutsuccess.jsp（無需登入）
- pom.xml檔案配置如下
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.oumuv</groupId> <artifactId>cas-clientA</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <name>cas-clientA</name> <description>cas client A</description> <dependencies> <dependency> <groupId>javax</groupId> <artifactId>javaee-web-api</artifactId> <version>7.0</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.3.9.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.9.RELEASE</version> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!--cas客戶端--> <dependency> <groupId>org.jasig.cas.client</groupId> <artifactId>cas-client-core</artifactId> <version>3.4.1</version> </dependency> </dependencies> <build> <finalName>cas-sample-java-webapp</finalName> <plugins> <!--指定jdk版本--> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.0</version> <configuration> <encoding>UTF-8</encoding> <source>1.8</source> <target>1.8</target> </configuration> </plugin> <plugin> <groupId>org.mortbay.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>8.1.9.v20130131</version> <configuration> <connectors> <connector implementation="org.eclipse.jetty.server.nio.SelectChannelConnector"> <!--埠--> <port>9001</port> <maxIdleTime>60000</maxIdleTime> </connector> </connectors> </configuration> </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"> <!-- 自動掃描該包，使SpringMVC認為包下用了@controller註解的類是控制器 --> <context:component-scan base-package="com.oumuv"/> <!-- 擴充了註解驅動，可以將請求引數繫結到控制器引數 --> <mvc:annotation-driven/> <!-- 訪問靜態資源 --> <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配置是重點，cas伺服器和客戶端的關聯需要在此配置：
<?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"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

</web-app>其中http://cas.server.com:8443是服務端的地址，http://cas.client1.com:9001是客戶端地址
- CASController.java有兩個業務如下：
/**
* 主頁
* @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、啟動專案、測試
依次啟動CAS-server服務端、CAS-clientA客戶端
訪問http://cas.client1.com:9001/index進入CAS-clientA主頁：
點選client A（http://cas.client1.com:9001/hello），會跳轉到cas登入認證頁面：
輸入賬號和密碼完成登入後跳轉到hello頁面：
到此專案搭建完成
