【问题描述】：

我尝试使用战争覆盖方法实现 cas 数据库身份验证。但我最终得到了错误，

我首先尝试设置基本的 cas，它成功了。当我尝试添加数据库身份验证时，只发生了这种情况。

而 developerConfigContext.xml 是，

<?xml version="1.0" encoding="UTF-8"?>
<!--
| deployerConfigContext.xml centralizes into one file some of the declarative configuration that
| all CAS deployers will need to modify.
|
| This file declares some of the Spring-managed JavaBeans that make up a CAS deployment.
| The beans declared in this file are instantiated at context initialization time by the Spring
| ContextLoaderListener declared in web.xml.  It finds this file because this
| file is among those declared in the context parameter "contextConfigLocation".
|
| By far the most common change you will need to make in this file is to change the last bean
| declaration to replace the default authentication handler with
| one implementing your approach for authenticating usernames and passwords.

标签： java spring maven cas

【解决方案1】：

如果我使用“QueryAndEncodeDatabaseAuthenticationHandler”，我知道我应该使用“queryEncodeDatabaseDataSource”。但这里我使用的是“SearchModeSearchDatabaseAuthenticationHandler”。

我能够通过使用 QueryAndEncodeDatabaseAuthenticationHandler 解决此问题。或者只是将“”添加到配置中。看来不管我们定义什么认证handler，cas都会先自动初始化QueryAndEncodeDatabaseAuthenticationHandler。

这是我的 deployerConfigContext.xml

【讨论】：

【解决方案3】：

在这里跟进，我认为这个问题实际上是一个在 4.2.2 中修复的错误。

【讨论】：

【解决方案4】：

只需在“deployerConfigContext.xml”中添加一行代码：

<alias name="dataSource" alias="queryEncodeDatabaseDataSource"/>

【讨论】：

【解决方案5】：

您没有关注文档。正如错误告诉您的那样，别名必须是 queryEncodeDatabaseDataSource。
