运行 Spring Session + Spring Boot 应用程序时出现运行时错误答案

【问题标题】：Runtime error while running a Spring Session + Spring Boot application运行 Spring Session + Spring Boot 应用程序时出现运行时错误
【发布时间】：2015-04-18 17:40:54
【问题描述】：

我正在尝试运行此Spring Session example available here，但我使用的是 Maven 而不是 Gradle。在 a) 运行 WAR 文件和 b) 在 WildFly8.2 服务器中部署 WAR 时，我都收到以下错误

快速搜索表明问题可能是 pom.xml 中引用的各种依赖项之间的版本冲突。

此错误的根本原因和解决方案是什么？

【问题讨论】：

那个异常意味着你有混合的依赖版本。不要为 Spring 将引入的依赖项指定您自己的版本，如果您需要不包含的其他 Spring 组件，请使用 Spring IO。
@chrylis 你是说对于所有 Spring 组依赖项，我最好删除版本？
@chrylis 我已经删除了除“spring-session-data-redis”之外的所有 Spring 组依赖项的版本号。如果我没有为此提及版本，我会收到 maven 构建错误，说明我应该提及此版本。但是，如果我只为此提供一个版本并生成 WAR，我仍然会不断收到上述原始错误。

【解决方案1】：

我看到几个地方需要清理：

您的 pom.xml 中有冲突的 Spring 版本。具体来说，spring-web-4.1.3 被明确列出，Spring Boot 1.1.10 引入了 Spring 4.0.8。从 pom 中删除尚未由 Spring Boot 管理的每个版本（Spring Session 和 Embedded-redis 除外）并让 spring-boot-starter-parent 管理它
一起移除 spring-web 依赖（它已经包含在 spring-boot-starter-web 中）
用 spring-boot-starter-security 替换安全依赖项

【讨论】：

这里有一点需要注意 - 您正在使用 com.orange.redis-embedded，它是原始嵌入式 redis 项目的一个分支：github.com/kstyrc/embedded-redis
