[英]Run spring boot application error: Cannot instantiate interface org.springframework.context.ApplicationListener
I have a spring project and try to make it use spring boot and to run at embadded tomcat following :我有一个 spring 项目,并尝试使用 spring boot 并在以下嵌入式 tomcat 上运行:
https://spring.io/guides/gs/rest-service/ https://spring.io/guides/gs/rest-service/
This is my Application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);
}
}
If I use maven command: mvn spring-boot:run
, the project starts fine, but I need to debug , so I run this main method at InteliJ, exception occurs: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,发生异常:

This is a symptom of a version mismatch somewhere in your Spring dependencies, but not necessarily just Spring Boot and Spring itself.这是 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。 I had this between my Spring Boot parent:我在我的 Spring Boot 父母之间有过这个:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.5.RELEASE</version>
<relativePath></relativePath>
</parent>
and my Spring Cloud Config dependency:和我的 Spring Cloud Config 依赖项:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-client</artifactId>
<version>1.0.4.RELEASE</version>
</dependency>
For some reason, I am not able to define the spring-cloud-config-client dependency without an explicit version declaration.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。
Updating both to the latest release version (1.3.5.RELEASE and 1.1.1.RELEASE) solved it.更新到最新版本(1.3.5.RELEASE 和 1.1.1.RELEASE)解决了这个问题。
Conclusion结论
Update your dependencies to the latest correct ones将您的依赖项更新为最新的正确依赖项
For ones using Gradle, I solved this issue setting the version of the Spring Boot Gradle Plugin in my library and in my main project to the same value:对于使用 Gradle 的人,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"
}
我遇到了同样的错误,我只是更改了 Spring Boot 父级的发布版本,现在一切正常
