添加spring-boot-starter-web时Spring Boot App启动时出错

[英]Error on Spring Boot App Startup when adding spring-boot-starter-web

使用spring-cloud-starter-aws-secrets-manager-config启动一个非常基本的Spring boot应用程序以检索AWS sectrets可以正常工作。 但是,当我将spring-boot-starter-web dependency到项目中以提供Web服务支持时, the spring-cloud-starter-aws-secrets-manager-config errors导致应用程序无法启动。

您正在混合1.5.x和2.x依赖项。 由于这两个版本之间存在重大更改,因此在同一项目中同时使用这两个版本时,经常会出现兼容性问题。

由于spring-cloud-starter-aws-secrets-manager-config仅支持2.x,因此您需要将spring boot starter parent升级到2.x版本。

@Michael McFadyen的回复是正确的; 但是,值得注意的是,手动添加Spring Cloud依赖及其版本不是一个好习惯。 应该改用dependencyManagement插件和Spring Cloud Release火车,以确保使用的所有Spring Cloud库都处于兼容版本中。请参阅项目页面中的“发行火车”部分。 它还包含有关哪些发行版与哪个Spring Boot版本相对应的信息。

如果要确保在构建文件中正确设置了Spring依赖项,则可以转到start.spring.io生成具有正确构建文件的项目存根。
