Go to your maven repository directory
For windows on below path
C:\Users\YourUser\.m2\repository\org\springframework\bootThen delete spring-boot-autoconfigurefolder.
转到您的 Maven 存储库目录对于下面路径上的 Windows
C:\Users\YourUser\.m2\repository\org\springframework\boot然后删除spring-boot-autoconfigure文件夹。
Now go to eclipse Right click on project -> Maven -> Update Project.

Add the import statement below your package declaration.
在包声明下方添加 import 语句。
import org.springframework.boot.autoconfigure.SpringBootApplication;
导入 org.springframework.boot.autoconfigure.SpringBootApplication;
You only need to add that annotation to your entry point, not every class. It goes on the same class that holds the main method to start Spring...
您只需要将该注释添加到您的入口点，而不是每个类。它位于包含启动 Spring 的主要方法的同一个类上......
public static void main(String[] args) {
SpringApplication.run(CourseAPIApp.class, args);
}

Neither of the above solutions worked for me as my code was this
上述解决方案都不适合我，因为我的代码是这样的
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.2.RELEASE</version>
</parent>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<properties>
<java.version>1.8</java.version>
</properties>
I was missing the <dependencies>tag which lead to this error.
我错过了<dependencies>导致此错误的标签。
