org.springframework.boot.autoconfigure.context.PropertyPlaceholderAutoConfiguration 上的错误处理条件

Question

将下面显示的 2 个依赖项添加到我的应用程序后一切正常，我的会话数据被写入我的本地 redis 服务器，但是当我尝试指定 redis 服务器的不同地址时出现错误。我认为错误与一些依赖问题有关，但我不知道如何解决这个问题。

 compile "org.springframework.boot:spring-boot-starter-data-redis-reactive:${springVersion}"
compile "org.springframework.session:spring-session-data-redis:${springVersion}"

启动时出错

Answer 1

这里发生了几件事。

您提供的日志表明类路径中缺少 javax.servlet.Filter 而您的构建脚本和依赖项建议您构建 Spring WebFlux 应用程序。我怀疑这是由于您使用 @EnableRedisHttpSession 明确配置 Spring Session 的 Servlet 支持（注意 HttpSession 在那里？）而不是 @EnableRedisWebSession 。更好的是，您应该将 Spring Session 配置留给 Spring Boot 以自动配置它 - 请参阅 Spring Boot 参考手册的 Spring Session 专用部分。

同样的建议（避免显式配置，依赖自动配置）适用于您的 Redis 配置，即不需要显式 LettuceConnectionFactory bean。

此外，对于 Spring Boot，强烈建议使用它的依赖管理，而不是显式提供依赖的版本，至少对于 Spring Boot 的依赖管理所涵盖的依赖。请参阅 Boot 参考手册的 依赖管理 和 依赖版本附录 部分。最重要的是，您还应该强烈考虑使用 Boot 的启动器来确保所有必需的依赖项都被引入 - 请参阅 启动器专用部分。
