我有一个弹簧项目并尝试使用spring boot并在以下的embadded tomcat中运行:
https://spring.io/guides/gs/rest-service/
这是我的申请
//@Configuration
//@EnableAspectJAutoProxy
@SpringBootApplication
@ComponentScan(basePackages = "gux.prome")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
如果我使用maven命令:mvn spring-boot:run
,项目启动正常,但我需要调试,所以我在InteliJ上运行这个main方法,发生异常:

这是Spring依赖项中版本不匹配某处的症状,但不一定只是Spring Boot和Spring本身。我在Spring Boot父级之间有这个:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-client</artifactId>
<version>1.0.4.RELEASE</version>
</dependency>
和我的Spring Cloud Config依赖:
{{1}}
出于某种原因,如果没有明确的版本声明,我无法定义spring-cloud-config-client依赖项。
将两者更新到最新版本(1.3.5.RELEASE和1.1.1.RELEASE)解决了这个问题。

将您的依赖项更新为最新的正确
答案 1 :(得分:0)
我有同样的错误,我刚刚更改了spring boot parent的发布版本,现在一切正常
答案 2 :(得分:0)
对于使用Gradle的用户,我解决了这个问题,将我的库和主项目中的Spring Boot Gradle插件的版本设置为相同的值:
plugins {
id("org.springframework.boot") version "2.2.2.RELEASE"
}
