设置春季会话，并通过XML重新使用现有的弹簧安全性

Question

我继承了使用弹簧组件的现有Web应用程序，包括Spring Security。

我需要添加使应用程序不播放的功能，以供云中托管，因此我正在尝试启用此应用程序的春季会话。但是，作为一个相对的春天新人，我很难做到这一点。

没有问题设置弹簧数据，将redis作为春季会议的前体工作，但是在春季会话文档上https://docs.spring.io/spring-session/docs/docs/current/current/referent/referent/referent/html5/#httpsession-xml-spring-configuration使我走上了连续的例外路径或内部服务器错误。

我正在发布pom.xml的所有/相关部分，applicationContext.xml，servlet-context.xml和web.xml文件，希望有人能告诉我我做错了什么，需要以不同的方式配置，或我缺少的东西，仍然需要添加。

我看到的错误是：

    ... 45 more

我在网上找到了一个建议，即我应该在我的pom.xml中包括生菜的依赖性来解决此问题：

<dependency>
  <groupId>biz.paluch.redis</groupId>
  <artifactId>lettuce</artifactId>
  <version>4.4.0.Final</version>
</dependency>

，但包括该依赖性产生了不同的例外，该例外说我现在有多个重复的实例：

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)

如果有人可以帮助我弄清楚我做错了什么，我将非常感激！

Answer 1

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)

例外意味着春季正在等待RedisConnectionFactory型豆类，但没有办法定义哪种豆是要使用的豆子，然后我认为它正在发生，因为在applicationContext.xml上，有一个bean清除为

<bean id="redisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:host-name="localhost" p:port="6379" />

，但在servlet-context.xml中也声明了一个bean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。

我的结论是RedisHttpSessionConfiguration期望RedisConnectionFactory型豆类，但由于有两个RedisConnectionFactory bean，因此无法注入。基于此，您可以尝试从servlet-context.xml中删除LettuceConnectionFactory BEAN，因为redisConnectionFactory BEAN是类型RedisConnectionFactory，并且已经从applicationContext.xml创建。

我希望此信息可以帮助您解决此问题。
