若依前后端分离项目集成CAS 5.3实现单点登录

绝地灬酷狼 2024-03-25 22:30 98阅读 0赞

#### 一.获取CAS5.3项目资源 ####

[GitHub - apereo/cas-overlay-template at 5.3][GitHub - apereo_cas-overlay-template at 5.3]

cas5.3.x还是基于jdk8运行，下一个版本6.0.x就基于jdk9了，随着cas版本升级要求jdk版本也越来越高，官网上和github上都有每个版本基本运行条件的说明，根据实际情况选择版本。

#### 二.tomcat部署 ####

1.  利用maven-package打war包

2.将war包放到tomcat的webapps目录下，启动tomcat

#### 三.支持HTTP协议 ####

1.  修改tomcat/webapps/cas/WEB-INF/classes/services/HTTPSandIMAPS-10000001.json文件，添加http支持，修改后代码如下。

![3014ddba1e7952a487bd73702488b422.png][]

1.  修改tomcat/webapps/cas/WEB-INF/classes/application.properties文件

添加如下两行

cas.tgc.secure=false
    cas.serviceRegistry.initFromJson=true

注释掉如下三行

#server.ssl.key-store=file:/etc/cas/thekeystore
    #server.ssl.key-store-password=changeit
    #server.ssl.key-password=changeit

1.  重启tomcat，访问登录页进行登录

cas默认密码在application.properties文件的最后一行

cas.authn.accept.users=casuser::Mellon

#### 四.前端代码 ####

1.  修改Navbar.vue，覆盖logout()方法

async logout() {
          this.$confirm('确定注销并退出系统吗？', '提示', {
            confirmButtonText: '确定',
            cancelButtonText: '取消',
            type: 'warning'
          }).then(() => {
            this.$store.dispatch('LogOut').then(() => {
              if (!defaultSettings.casEnable) {
                location.href = this.$router.options.base + "/index";
              }
              //location.href = '/index';
            })
          }).catch(() => {});
        }

1.  修改permission.js文件，复制代码粘贴到红框位置，适当修改地址，注意导包。

if (!defaultSettings.casEnable) {
            next(`/login?redirect=${to.fullPath}`) // 否则全部重定向到登录页
          }
          // 开启cas
          if (defaultSettings.casEnable) {
            window.location.href = defaultSettings.casloginUrl // 否则全部重定向到登录页
          }

![73390a1cf089bcd362e68227d070e632.png][]

1.  修改settings.js文件，添加如下配置，适当修改地址，service前是前面部署的cas服务地址，service后是自己的系统后端服务地址

/**
       * 开启cas
       */
      casEnable: false,
      /**
       * 单点登录url
       */
      casloginUrl:
        'http://cpmp.fulongai.cn/cas/login?service=http://192.168.2.154:8080',
      /**
       * 单点登出url
       */
      caslogoutUrl:
        'http://cpmp.fulongai.cn/cas/logout?service=http://192.168.2.154:8080'

1.  修改user.js文件，替换LogOut方法，注意导包。

LogOut({ commit, state }) {
          return new Promise((resolve, reject) => {
            logout(state.token).then(() => {
              commit('SET_TOKEN', '')
              commit('SET_ROLES', [])
              commit('SET_PERMISSIONS', [])
              commit('SET_PROJECT', {})
              sessionStorage.removeItem('dmp-projectId')
              removeToken()
              resolve()
              window.location.href = defaultSettings.caslogoutUrl
            }).catch(error => {
              reject(error)
            })
          })
        }

1.  修改request.js文件，注释掉红框中代码

        }
    }

1.  framework.config.properties下新增CasProperties.java类

#### 六.自定义数据源 ####

CAS应用到项目时，不可能一直使用默认账号登录，可连接项目数据库进行用户信息验证。

1.修改application.properties文件，添加数据源

cas.authn.jdbc.query[0].driverClass=com.mysql.jdbc.Driver
    cas.authn.jdbc.query[0].url=jdbc:mysql://192.168.2.156:3306/cpmplatform?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=GMT%2B8
    cas.authn.jdbc.query[0].user=cpmp
    cas.authn.jdbc.query[0].password=123456
    cas.authn.jdbc.query[0].sql=select password from sys_user where user_name=?
    cas.authn.jdbc.query[0].fieldPassword=password
    cas.authn.jdbc.query[0].passwordEncoder.type=BCRYPT
    cas.authn.jdbc.query[0].passwordEncoder.characterEncoding=UTF-8

fieldPassword：数据库中密码字段列名

sql：密码查询语句，项目在实际应用中还可以增加条件，用户删除标志、用户状态等。

2.注释掉application.properties文件最后一行的默认用户名密码

#cas.authn.accept.users=casuser::Mellon

3.重启tomcat，使用系统用户登录，可登陆成功。

#### 七.跨域问题 ####

集成CAS过程中遇到的跨域问题，以及单点登录内嵌页面时的复杂跨域问题，单独整理了一篇，目前遇到的CORS报错都能解决：

[https://blog.csdn.net/secretdaixin/article/details/129240863?spm=1001.2014.3001.5501][https_blog.csdn.net_secretdaixin_article_details_129240863_spm_1001.2014.3001.5501]

#### 八.自定义登录页 ####

本例中主题名称为cpmp，以下代码将以cpmp命名进行讲解。

1.  classes/static/themes目录下新建以主题名称命名的文件夹用于存放静态文件，css、js、图片等。

![68b327538b45fec86ca09d51ac8c5831.png][]

1.  classes目录下创建以主题名称命名的properties文件，本例文件名为cpmp.properties，用于配置主题所引用的资源的路径。前2~4行默认主题样式不能丢，否则页面会丢样式。下面的配置是步骤1创建的目录及文件。等号前的变量名称自定义即可，此变量会在步骤3创建的登录页面中引用。

# 系统默认主题样式
    cas.standard.css.file = /css/cas.css
    cas.javascript.file = /js/cas.js
    cas.admin.css.file = /css/admin.css
    
    # 自定义JS
    login.js.element-ui = /themes/cpmp/js/element-ui.js
    login.js.jquery = /themes/cpmp/js/jquery.min.js
    login.js.cas = /themes/cpmp/js/cas.js
    
    # 自定义CSS
    login.css.element-ui = /themes/cpmp/css/element-ui.css
    index.css.style = /themes/cpmp/css/cas.css
    
    # 其它
    login.img.path = /themes/cpmp/img
    cas.page.title = cpmp

1.  classes/templates目录下新建以主题名称命名的文件夹用于存放登录页面，登录页面是一个固定名称的html文件，必须以casLoginView.html命名。

<!DOCTYPE html>
    <html lang="en">
    <head>
      <meta charset="UTF-8">
      <meta http-equiv="X-UA-Compatible" content="IE=edge">
      <link rel="stylesheet" th:href="@{${#themes.code('index.css.style')}}"/>
      <link rel="stylesheet" th:href="@{${#themes.code('login.css.elementui')}}"/>
    </head>
    <body>
      
      <div class="container">
        <div class="login">
          <h3>C A S 登录</h3>
          <form id="postForm" autocomplete="off" method="post" th:object="${credential}">
            <input type="hidden" name="execution" th:value="${flowExecutionKey}"/>
            <input type="hidden" name="_eventId" value="submit"/>
            <input type="hidden" name="geolocation"/>
            <i class="iconfont icon-man"></i>
            <input
              id="username"
              size="25"
              v-model.trim="username"
              tabindex="1"
              placeholder="请输入用户名"
              type="text"
              th:disabled="${guaEnabled}"
              th:field="*{username}"
              th:accesskey="#{screen.welcome.label.netid.accesskey}"
              autocomplete="off"
            />
            <i class="iconfont icon-suo"></i>
            <input
              type="password"
              id="password"
              size="25"
              tabindex="2"
              placeholder="请输入密码"
              th:accesskey="#{screen.welcome.label.password.accesskey}"
              th:field="*{password}"
              autocomplete="off"
            />
            <div th:if="${#fields.hasErrors('*')}">
              <span th:each="err : ${#fields.errors('*')}" th:utext="${err}" ></span>
            </div>
    
            <input
              name="submit"
              accesskey="l"
              th:value="#{screen.welcome.button.login}"
              type="submit"
              value="登录"
            />
          </form>
        </div>
      </div>
    
    </body>
    </html>

1.  在classes/service目录下的服务注册文件中，为每个服务指定主题，以模板中默认的服务注册文件为例，也可以是自建的服务注册文件。

![ebc4ff16e74f21293fc153e4af56725e.png][]

1.  修改classes目录下的application.properties文件，增加代码用于指定默认主题

# 默认主题
    cas.theme.defaultThemeName=cpmp

1.  将文件发布到tomcat，重启tomcat，访问登录页面，主题配置成功。
