CAS之5.2x版本自定義登入,多資料來源登入-yellowcong
阿新 • • 發佈:2019-02-15
通過自定義登入的策略,可以根據傳遞過來的引數,來確定使用那個資料庫查詢使用者資訊。這種方式,可以說是,爽歪歪啊。可以自己登入,設定資料來源來訪問。我後期加jdbctemplate的配置,將jdbc整合springboot裡面,這樣用的是springboot裡面資料來源。
學習要求
需要對於cas和springboot環境搭建有所瞭解,不然看著,都不知道我說得啥玩意。

目錄結構
新增登入處理類
登入處理類,需要繼承AbstractPreAndPostProcessingAuthenticationHandler
驗證類
登入驗證類,這個類用於處理使用者登入的請求。大家可以發現,當我是admin的時候,不管是啥情況,俺都返回資料,如果是lock ,我就鎖住類。我還可以從資料庫中查詢資料,判斷使用者的情況。

throw new FailedLoginException();
} else if (username.startsWith("account")) {
//賬號錯誤
throw new AccountLockedException();
}
return null;
}

配置注入類
我們寫好了處理登入的類後,需要注入到springboot,這樣我們才可以呼叫到我們的自定義登入類
package com.yellowcong.auth.conf;
import org.apereo.cas.authentication.AuthenticationEventExecutionPlan;
import org.apereo.cas.authentication.AuthenticationEventExecutionPlanConfigurer;
import org.apereo.cas.authentication.AuthenticationHandler;
import org.apereo.cas.authentication.principal.DefaultPrincipalFactory;
import org.apereo.cas.services.ServicesManager;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import com.yellowcong.auth.handler.CustomerHandler;
/**
* @author yellowcong
* 建立日期:2018/02/02
*
*/
public class CustomConfiguration implements AuthenticationEventExecutionPlanConfigurer {
@Autowired
@Qualifier("servicesManager")
private ServicesManager servicesManager;
//註冊驗證器
@Bean
public AuthenticationHandler customAuthenticationHandler() {
//優先驗證
return new CustomerHandler("customerHandler",
servicesManager, new DefaultPrincipalFactory(), 1);
}
//註冊自定義認證器
@Override
public void configureAuthenticationExecutionPlan(final AuthenticationEventExecutionPlan plan) {
plan.registerAuthenticationHandler(customAuthenticationHandler());
}
}
package
用於讓springboot知道這個是根目錄,下面有類可以掃描注入
/**
* @author yellowcong
* 建立日期:2018/02/02
*
*/
package com.yellowcong.auth;
配置spring.factories
SpringFactoriesLoader屬於Spring框架私有的一種擴充套件方案,其主要功能就是從指定的配置檔案META-INF/spring.factories載入配置。通過這個方法,我們就能將自定義的認證信方法。
org.springframework.boot.autoconfigure.EnableAutoConfiguration=com.yellowcong.auth.conf.CustomConfiguration
debug方式帶詳情啟動cas
#加上-X 就可以檢視詳情了
build.cmd debug -X
專案pom.xml
為啥我要把這個單獨貼出來,因為我添加了一些依賴,如果不新增這些依賴,咋們就不能愉快的玩耍了。

登入驗證
表資料
CREATE DATABASE /*!32312 IF NOT EXISTS*/`yellowcong` /*!40100 DEFAULT CHARACTER SET utf8 */;
USE `yellowcong`;
DROP TABLE IF EXISTS `cas_user`;
CREATE TABLE `cas_user` (
`username` varchar(32) NOT NULL DEFAULT '',
`password` varchar(32) NOT NULL DEFAULT ''
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
insert into `cas_user`(`username`,`password`) values ('yellowcong','yellowcong'),('doubi','doubi');
登入驗證
登入我們的配置,登入後,我將資料來源裡面添加了一條資料(zhangsan:zhangsan),然後也能擋路上。

錯誤集合
找不到類自定義的類
這個報錯,就是沒有找到我們預設填寫的處理類。我剛開始一臉矇蔽,後來發現是pom.xml檔案中配置的編譯版本的問題。
外掛版本是3.1.0的,預設是2點幾的版本,就是由於這個才導致報錯的,害我找半天,鬱悶死我了。
