不是因为springfox，我使用mqtt有问题

@weir2010 您能否为您的评论提供更多背景信息？我没有看到 MQTT 和 Web 请求路径解析之间的联系。

@weir2010 目前还不清楚您在上面的评论中提供的示例代码如何与您最初发布的堆栈跟踪相关。如果您认为这是 Spring Boot 问题，请提供一个示例应用程序（作为 github 项目的 zip 文件），该应用程序可重现该问题并且不包含 springfox 作为依赖项。

我发现了问题。真的很招摇ok

我对最新的 Spring 版本 2.6.1 和 springfox-swagger2 版本 3.0.0 也有同样的问题。有解决方法吗？

JuKu

与上面提到的同样的问题

notforward

任何更新？有计划发布固定版本吗？

rcbandit111

请在发表评论之前阅读问题历史记录。这是 springfox 的问题，我们在这里无能为力。

snicoll

要解决此问题，您可以添加@EnableWebMvc到 spring-context。你需要禁用测试，@Profile(!test) @EnableWebMvc

这将使您能够解决该问题。

感谢您尝试提供帮助，@mert-unsal。不幸的是，这几乎肯定会产生额外的不良影响，因为它将禁用 Spring Boot 的所有 Spring MVC 自动配置。

您可以在驱动器 SQL (POSTGRES) 中安装 JAR，直接退出 pom 项目并聚合构建路径和编译。
