通过 XML 使用现有 Spring 安全性设置 Spring 会话和 Redis
Setting up Spring Session and Redis via XML with existing Spring Security
我继承了一个现有的 Web 应用程序，该应用程序使用了 Spring 个组件，包括 Spring 安全性。
我需要添加使应用程序无会话的功能，以便在云中托管，因此我尝试为此应用程序启用 Spring 会话。不过，作为一个亲戚 Spring 新人，我在做这件事时遇到了一些困难。
使用 Redis 设置 Spring 数据作为 Spring 会话的前身工作没有问题，但是遵循 https://docs.spring.io/spring-session/docs/current/reference/html5/#httpsession-xml-spring-configuration 的 Spring 会话文档让我失望了连续异常或内部服务器错误的路径。
我正在发布 pom.xml、applicationContext.xml、servlet-context.xml 和 web.xml 文件的 all/relevant 部分，希望有人能告诉我我做错了什么，需要不同的配置，或者我遗漏了什么但仍然需要添加。
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 中加入对生菜的依赖来解决这个问题：
<dependency>
<groupId>biz.paluch.redis</groupId>
<artifactId>lettuce</artifactId>
<version>4.4.0.Final</version>
</dependency>
但包括该依赖项会生成一个不同的异常，它表示我现在有多个 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！

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)
异常意味着 spring 正在等待类型为 RedisConnectionFactory 的 bean，但是没有办法定义要使用的 bean，那么我认为它正在发生，因为在applicationContext.xml 有一个 bean 被清除为
<bean id="redisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:host-name="localhost" p:port="6379" />
而且在 servlet-context.xml 中还有一个 bean 声明为：
<bean class="org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory"/>
并且根据 JedisConnectionFactory 和 LettuceConnectionFactory 的 javadoc，它们都实现了 RedisConnectionFactory 接口。
我的结论是 RedisHttpSessionConfiguration 需要一个类型为 RedisConnectionFactory 的 bean，但它无法注入，因为有两个 RedisConnectionFactory bean。基于此，您可以尝试从 servlet-context.xml 中删除 LettuceConnectionFactory bean，因为 redisConnectionFactory bean 的类型为 RedisConnectionFactory 并且已经从 applicationContext.xml.[=27 创建了=]
我希望这些信息可以帮助您解决这个问题。

我在网上找到了一个建议，我应该在我的 pom.xml 中加入对生菜的依赖来解决这个问题：
<dependency>
<groupId>biz.paluch.redis</groupId>
<artifactId>lettuce</artifactId>
<version>4.4.0.Final</version>
</dependency>
但包括该依赖项会生成一个不同的异常，它表示我现在有多个 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！

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)
异常意味着 spring 正在等待类型为 RedisConnectionFactory 的 bean，但是没有办法定义要使用的 bean，那么我认为它正在发生，因为在applicationContext.xml 有一个 bean 被清除为
<bean id="redisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:host-name="localhost" p:port="6379" />
而且在 servlet-context.xml 中还有一个 bean 声明为：
<bean class="org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory"/>
并且根据 JedisConnectionFactory 和 LettuceConnectionFactory 的 javadoc，它们都实现了 RedisConnectionFactory 接口。
我的结论是 RedisHttpSessionConfiguration 需要一个类型为 RedisConnectionFactory 的 bean，但它无法注入，因为有两个 RedisConnectionFactory bean。基于此，您可以尝试从 servlet-context.xml 中删除 LettuceConnectionFactory bean，因为 redisConnectionFactory bean 的类型为 RedisConnectionFactory 并且已经从 applicationContext.xml.[=27 创建了=]
我希望这些信息可以帮助您解决这个问题。
