由于需要从业务上将系统拆分成多个独立的子系统,所以需要sso。这里主要是讲述一下server 端的配置.
在 https://github.com/apereo/cas 可以下载cas-server 的源代码
也可以在直接使用maven 进行构建。
如果是下载源码,那么复制里面的工程(cas-server-webapp)也是一样的
1、创建一个maven 工程, 后面附上 依赖文件。
2、复制从github 下载的 cas-server-webapp 中 src/main/webapp 内容 到 webapp 中,并且将resources 中的文件复制到 resources 中,目的是减少配置。
这两个文件夹中主要是配置文件。不要遗漏。
pom.xml 文件。

很多教程都是一来就介绍怎么配置https 这里先不进行ssl 配置,使用http
WEB-INF/spring-configuration/ticketGrantingTicketCookieGenerator.xml
<!-- TODO 这里将 cookieSecure 修改为了false ,目的是使用http -->
<bean id="ticketGrantingTicketCookieGenerator"
class="org.jasig.cas.web.support.CookieRetrievingCookieGenerator"
c:casCookieValueManager-ref="cookieValueManager"
p:cookieSecure="false"
p:cookieMaxAge="-1"
p:cookieName="TGC"
p:cookiePath=""/>
- 国际化的配置 WEB-INF/cas-servlet.xml
<bean id="localeResolver"
class="org.springframework.web.servlet.i18n.CookieLocaleResolver"
p:defaultLocale="zh_CN" />
- 认证处理配置 WEB-INF/deployerConfigContext.xml
<!-- TODO 这里设置 p:requireSecure="false" 目的是为了使用http -->
<bean id="proxyAuthenticationHandler"
class="org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler"
p:requireSecure="false"
p:httpClient-ref="supportsTrustStoreSslSocketFactoryHttpClient" />
这样http 就配置完成了! 可以进行测试一下了
<!-- 加密方式配置 -->
<bean id="MD5PasswordEncoder" class="org.jasig.cas.authentication.handler.DefaultPasswordEncoder">
<constructor-arg index="0" value="MD5" />
</bean>
<!-- Oracle connector -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:ytym" />
<property name="username" value="xxx" />
<property name="password" value="xxx" />
</bean>
<!-- 使用自定义的查询方式验证用户信息 -->
<bean id="primaryAuthenticationHandler"
class="org.jasig.cas.adaptors.jdbc.QueryDatabaseAuthenticationHandler">
<property name="dataSource" ref="dataSource" />
<property name="passwordEncoder" ref="MD5PasswordEncoder"/>
<property name="sql" value="select login_pass from user where name = ? " />
</bean>
==QueryDatabaseAuthenticationHandler可以自己实现,根据业务的需要==
3、允许使用cas 认证的服务配置。
默认的配置是用是json 的格式进行配置 resource/services 文件中,但是修改起来难度比较大, 所以这里使用xml 的配置
找到 WEB-INF/deployerConfigContext.xml 中的 serviceRegistryDao 进行修改
<!-- 这里注释掉, 使用xml 的配置 方式 -->
<bean id="serviceRegistryDao" class="org.jasig.cas.services.InMemoryServiceRegistryDaoImpl"
p:registeredServices-ref="registeredServicesList" />
<util:list id="registeredServicesList">
<!--<bean class="org.jasig.cas.services.RegexRegisteredService">-->
<!--<property name="id" value="10000001"/>-->
<!--<property name="name" value="HTTPS and IMAPS"/>-->
<!--<property name="description" value="This service definition authorized all application urls that support HTTPS and IMAPS protocols."/>-->
<!--<property name="serviceId" value="^(https|imaps)://.*"/>-->
<!--<property name="evaluationOrder" value="10000001"/>-->
<!--</bean>-->
<bean class="org.jasig.cas.services.RegexRegisteredService">
<property name="id" value="10000002"/>
<property name="name" value="localhost Test"/>
<property name="description" value="local server config"/>
<property name="serviceId" value="^(http?|https?|imaps?)://((127\.0\.0\.1)|(localhost)|(test.com))(:[\d]+)?/.*"/>
<property name="evaluationOrder" value="10000002"/>
</bean>
<bean class="org.jasig.cas.services.RegexRegisteredService">
<property name="id" value="10000003"/>
<property name="name" value="ydzx online website"/>
<property name="description" value="ydzx online"/>
<property name="serviceId" value="^(http?|https?|imaps?)://[\w]+.ydzxlm.com/.*"/>
<property name="evaluationOrder" value="10000002"/>
</bean>
</util:list>
自己写验证码的实现,并且写好验证码验证的接口
实现可以见后面的代码
1、在 配置验证bean
WEB-INF/cas-servlet.xml
<!-- 验证码验证 验证码超时时间,默认是五分钟 -->
<bean id="authCodeValidateFormAction" class="com.ydzx.cas.server.web.flow.AuthCodeValidateFormAction" />
2、配置登录流程
WEB-INF/webflow/login/login-webflow.xml
<view-state id="viewLoginForm" view="casLoginView" model="credential">
<binder>
<binding property="username" required="true"/>
<binding property="password" required="true"/>
</binder>
<on-entry>
<set name="viewScope.commandName" value="‘credential‘"/>
<!--
<evaluate expression="samlMetadataUIParserAction" />
-->
</on-entry>
<!--<transition on="submit" bind="true" validate="true" to="realSubmit"/>-->
<!-- 修改,目的是在登录的时候,加上验证码的验证 -->
<transition on="submit" bind="true" validate="true" to="authCodeValidate"/>
</view-state>
<!-- 添加一个新的流程,在登录前添加验证码 -->
<action-state id="authCodeValidate" >
<evaluate expression="authCodeValidateFormAction.validate(flowRequestContext,flowScope.credential, messageContext)" />
<transition on="success" to="realSubmit" />
<transition on="error" to="generateLoginTicket" />
</action-state>
验证码实现类 : VerfiyCode.java
public class VerfiyCode {
private String randomCode;
public VerfiyCode() {
System.setProperty("java.awt.headless", "true");
}
Color getRandColor(int fc, int bc) {// 给定范围获得随机颜色
Random random = new Random();
if (fc > 255)
fc = 255;
if (bc > 255)
bc = 255;
int r = fc + random.nextInt(bc - fc);
int g = fc + random.nextInt(bc - fc);
int b = fc + random.nextInt(bc - fc);
return new Color(r, g, b);
}
/**
* 获取图片
*/
public BufferedImage getImage() {
// 在内存中创建图象
int width = 60, height = 20;
BufferedImage image = new BufferedImage(width, height,
BufferedImage.TYPE_INT_RGB);
// 获取图形上下
Graphics g = image.getGraphics();
// 生成随机
Random random = new Random();
// 设定背景
g.setColor(getRandColor(200, 250));
g.fillRect(0, 0, width, height);
// 设定字体
g.setFont(new Font("Times New Roman", Font.PLAIN, 18));
// 画边
g.setColor(new Color(255, 255, 255));
g.drawRect(0, 0, width - 1, height - 1);
// 随机产生155条干扰线,使图象中的认证码不易被其它程序探测
g.setColor(getRandColor(160, 200));
for (int i = 0; i < 155; i++) {
int x = random.nextInt(width);
int y = random.nextInt(height);
int xl = random.nextInt(12);
int yl = random.nextInt(12);
g.drawLine(x, y, x + xl, y + yl);
}
// 取随机产生的认证 (4位数 )
String sRand = "";
for (int i = 0; i < 4; i++) {
String rand = String.valueOf(random.nextInt(10));
sRand += rand;
// 将认证码显示到图象中
g.setColor(new Color(20 + random.nextInt(110), 20 + random
.nextInt(110), 20 + random.nextInt(110)));
// 调用函数出来的颜色相同,可能是因为种子太接近,所以只能直接生
g.drawString(rand, 13 * i + 6, 16);
}
// 将认证码存入
this.setRandomCode(sRand);
// session.setAttribute("rand",sRand);
// 图象生效
g.dispose();
// 输出图象到页
return image;
}
/**
* 随机数
*/
public String getRandomCode() {
return this.randomCode;
}
public void setRandomCode(String randomCode) {
this.randomCode = randomCode;
}
}
AuthCodeValidateFormAction.java 验证码验证实现
public class AuthCodeValidateFormAction {
protected final Logger logger = LoggerFactory.getLogger(getClass());
private long outTime = 5*60*1000;
public static final String SUCCESS = "success";
public static final String ERROR = "error";
public Event validate(final RequestContext context, final Credential credential,
final MessageContext messageContext) {
try {
HttpServletRequest request = WebUtils.getHttpServletRequest(context);
String image_code = (String) request.getSession().getAttribute("image_no");
Long image_create_time = (Long) request.getSession().getAttribute("image_create_time");
if( (image_create_time != null && Math.abs(System.currentTimeMillis() - image_create_time) > outTime)
|| (image_code == null) ){
resultMsgWrapper(messageContext,"验证码超时!");
return new Event(this, ERROR);
}
String username = request.getParameter("username");
if (username == null) {
resultMsgWrapper(messageContext,"用户信息不能为空!");
return new Event(this, ERROR);
}
String[] separator_chars = username.split("#@#");
if(separator_chars.length < 2){
resultMsgWrapper(messageContext,"信息不合法!");
return new Event(this, ERROR);
}
if(separator_chars[1] == null && StringUtils.isEmpty(separator_chars[1])){
resultMsgWrapper(messageContext,"验证码不能为空!");
return new Event(this, ERROR);
}
if (image_code != null && image_code.trim().equals(separator_chars[1])) {
request.getSession().removeAttribute("image_no");
} else {
resultMsgWrapper(messageContext,"验证码信息错误!");
return new Event(this, ERROR);
}
return newEvent(SUCCESS);
} catch (final Exception e) {
logger.debug(e.getMessage(), e);
return newEvent(ERROR, e);
}
}
private void resultMsgWrapper(MessageContext messageContext,String msg) {
MessageBuilder msgBuilder = new MessageBuilder();
msgBuilder.defaultText(msg);
messageContext.addMessage(msgBuilder.error().build());
}
/**
* New event based on the given id.
*
* @param id the id
* @return the event
*/
private Event newEvent(final String id) {
return new Event(this, id);
}
/**
* New event based on the id, which contains an error attribute referring to the exception occurred.
*
* @param id the id

*/
private Event newEvent(final String id, final Exception error) {
return new Event(this, id, new LocalAttributeMap("error", error));
}
public long getOutTime() {
return outTime;
}
public void setOutTime(long outTime) {
this.outTime = outTime;
}
}

response.setHeader("Pragma", "No-cache");
response.setHeader("Cache-Control", "no-cache");

response.reset();
VerfiyCode verfiyCode = new VerfiyCode();
ImageIO.write(verfiyCode.getImage(), "JPEG", response.getOutputStream());
