我有一个 spring 项目并尝试让它使用 spring boot 并在嵌入的 tomcat 上运行:

https://spring.io/guides/gs/rest-service/

这是我的应用程序

//@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运行这个main方法，出现异常:

最佳答案

这是您的 Spring 依赖项中某处 版本不匹配的症状，但不一定只是 Spring Boot 和 Spring 本身。我在我的 Spring Boot parent 之间有这个:

<parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>1.3.5.RELEASE</version>
  <relativePath></relativePath>
</parent>

还有我的 Spring Cloud Config 依赖:

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-config-client</artifactId>
  <version>1.0.4.RELEASE</version>
</dependency>

由于某种原因，如果没有明确的版本声明，我无法定义 spring-cloud-config-client 依赖项。

将两者都更新到最新版本(1.3.5.RELEASE 和 1.1.1.RELEASE)解决了这个问题。

结论
将你的依赖更新到最新的正确的
