【问题描述】：
我继承了一个使用 Spring 组件（包括 Spring Security）的现有 Web 应用程序。
我需要添加使应用程序无会话的功能，以便在云中托管，因此我正在尝试为此应用程序启用 Spring Session。但是，作为一个相对 Spring 的新手，我在做这件事时遇到了一些困难。
使用 Redis 将 Spring Data 设置为 Spring Session 的前身工作没有任何问题，但是遵循 https://docs.spring.io/spring-session/docs/current/reference/html5/#httpsession-xml-spring-configuration 上的 Spring Session 文档让我走上了连续异常或内部服务器错误的道路。
我发布了 pom.xml、applicationContext.xml、servlet-context.xml 和 web.xml 文件的所有/相关部分，希望有人能告诉我我做错了什么，需要进行不同的配置，或者我缺少的东西仍然需要添加。
我看到的错误是：

我在网上找到了一个建议，我应该在我的 pom.xml 中包含一个生菜依赖项来解决这个问题：
<dependency>
<groupId>biz.paluch.redis</groupId>
<artifactId>lettuce</artifactId>
<version>4.4.0.Final</version>
</dependency>
但包含该依赖项会生成一个不同的异常，这表示我现在有多个 RedisConnectionFactory 实例：
org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [org.springframework.data.redis.connection.RedisConnectionFactory] is defined: expected single matching bean but found 2: org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory#0,redisConnectionFactory)
如果有人能帮助我找出我做错了什么，我将不胜感激！

【问题讨论】：

谢谢你，丹尼尔。您的解决方案对我有用 - 我只需要删除创建 RedisConnectionFactory 接口的双实例的额外 bean。
