添加spring-boot-starter-web

时间:2019-07-03 11:23:21

标签: java spring-boot spring-cloud aws-secrets-manager

使用spring-cloud-starter-aws-secrets-manager-config来检索AWS sectrets来启动一个非常基本的 Spring boot 应用程序是正确的。但是,当我将spring-boot-starter-web dependency添加到项目中以获取Web服务支持the spring-cloud-starter-aws-secrets-manager-config errors时,应用程序无法启动。

您正在混合使用1.5.x和2.x依赖性。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父级升级到2.x版本。

@Michael McFadyen的回答是正确的;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。应该改为使用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project page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。

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