spring-cloud-starter-config 和 spring-boot-devtools 如何一起使用？
How to use spring-cloud-starter-config and spring-boot-devtools together?
spring-cloud-starter-config 本身和 spring-boot-devtools 一样完美，但是当我创建一个同时使用两者的项目时，我收到此错误：

我需要配置或设置什么特别的东西才能在同一个项目中获得 spring-cloud-starter-config 和 spring-boot-devtools 的好处吗？
我试图通过 Spring Initializr 重新创建您的 pom.xml 并且下面的 pom.xml 成功地启动了 SpringBootApplication。
你可以与你的交叉检查，只是一些快速的要点：
spring-boot-starter 不需要，因为你有 spring-boot-starter-web
spring-cloud-starter-bootstrap 不是必需的（至少 Spring Initializr 没有把它和 spring-cloud-starter-config
放在一起
我没有包括 spring-batch-test 和 spring-security-test 因为你似乎没有使用相关的启动器。
