问题产生背景

cas项目部署多台时session无法共享而引发一系列局限性，鉴于此考虑对cas项目进行session共享改造，基于redis来存储共享session信息。

项目改造内容

项目加载配置ticketRegistry.xml文件增加如下配置，其中context:annotation-config/ 如果之前已经有这个配置的话可以不用增加。

<context:annotation-config/>
<bean class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
        <property name="redisNamespace" value="${redis.prefix}"></property>
</bean>

redisNamespace 自定义redis文件目录，默认是spring:session:下。
pom.xml增加如下jar包引入

<dependency>
      <groupId>org.springframework.session</groupId>
      <artifactId>spring-session-data-redis</artifactId>
      <version>1.2.0.RELEASE</version>
    </dependency>

    <!-- https://mvnrepository.com/artifact/cglib/cglib -->
    <dependency>
      <groupId>cglib</groupId>
      <artifactId>cglib</artifactId>
      <version>3.2.11</version>
    </dependency>

web.xml需要在所有过滤器前增加如下过滤器

<filter>
    <filter-name>springSessionRepositoryFilter</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>springSessionRepositoryFilter</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>ERROR</dispatcher>
  </filter-mapping>
  <filter>

java.lang.IllegalStateException: Cannot load configuration class: org.springframework.session.data.r_数据库

异常处理

改造完成之后在本地可以正常启动正常访问，但是上到线上服务器之后会出现如下错误信息

初步排查可能为jar包冲突所致，经过排查发现，需要去掉原来已经对项目中cglib jar包引入

java.lang.IllegalStateException: Cannot load configuration class: org.springframework.session.data.r_java_02

以及排除

java.lang.IllegalStateException: Cannot load configuration class: org.springframework.session.data.r_apache_03

排除之后可以正常启动正常访问，问题解决。
