java - 使用现有的 Spring Security 通过 XML 设置 Spring Session 和 Redis

转载作者：行者123 更新时间：2023-12-02 02:37:54

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成为无 session 的功能，以便在云中托管，因此我尝试为此应用程序启用 Spring Session。不过，作为一个 Spring 新手，我在这方面遇到了一些困难。

使用 Redis 设置 Spring Data 作为 Spring Session 的前期工作没有任何问题，但遵循 Spring Session 文档 https://docs.spring.io/spring-session/docs/current/reference/html5/#httpsession-xml-spring-configuration导致我陷入了连续的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，或者我缺少什么但仍需要添加。

我看到的错误是:

我在网上发现了一个建议，我应该在我的 pom.xml 中包含生菜的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不同的异常，这表明我现在有多个 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，我将非常感激!

最佳答案

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)

该异常意味着 spring 正在等待 RedisConnectionFactory 类型的 bean，但无法定义要使用哪个 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"/>

根据JedisConnectionFactory和LettuceConnectionFactory的javadoc，它们都实现了RedisConnectionFactory接口(interface)。

我的结论是，RedisHttpSessionConfiguration 需要一个 RedisConnectionFactory 类型的 bean，但无法注入(inject)，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 创建。

希望这些信息可以帮助您解决这个问题。
