I had the same problem and I tried above solutions. But I have found a different issue.
我遇到了同样的问题，我尝试了上述解决方案。但我发现了一个不同的问题。
In latest springframework, this org.springframework.boot.autoconfigure.jdbc.DataSourceBuilderhas been moved to
org.springframework.boot.jdbc.DataSourceBuilder. so you have to edit in import
在最新的springframework 中，这 org.springframework.boot.autoconfigure.jdbc.DataSourceBuilder已移至
org.springframework.boot.jdbc.DataSourceBuilder. 所以你必须在导入中进行编辑
And then you will notice that you have to use DataSourceBuilder.create(classLoader)instead of new DataSourceBuilder(classLoader)
然后你会注意到你必须使用DataSourceBuilder.create(classLoader)而不是new DataSourceBuilder(classLoader)

Go to your maven repository directory
For windows on below path

There is a copy/paste error - the code from the official documentation (https://spring.io/guides/gs/rest-service/) is:
有一个复制/粘贴错误——来自官方文档（https://spring.io/guides/gs/rest-service/）的代码是：
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.context.annotation.ComponentScan;
@ComponentScan
@EnableAutoConfiguration
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
The code in the question is missing ".EnableAutoConfiguration" in the first line.
问题中的代码在第一行中缺少“.EnableAutoConfiguration”。

In case anyone else has this issue, I was able to solve this by deleting the spring-boot-autoconfigure artifacts from my local Maven repository and updating my project in Eclipse (which re-downloads the artifacts).
如果其他人遇到此问题，我可以通过从本地 Maven 存储库中删除 spring-boot-autoconfigure 工件并在 Eclipse（重新下载工件）中更新我的项目来解决此问题。

if you are using eclise then Right button on project -> Maven -> Update Project
如果您使用的是 eclise，则在项目上右键 -> Maven -> 更新项目
回答by Siddhant Tanpure
If you are using IntelliJ IDEA Right click on project -> Maven -> Reimport Also, try "Generate source and update folder" below the reimport if above method doesn't work. No need to delete any spring or maven folder or files.
如果您使用的是 IntelliJ IDEA 右键单击项目 -> Maven -> 重新导入此外，如果上述方法不起作用，请尝试重新导入下方的“生成源和更新文件夹”。无需删除任何 spring 或 maven 文件夹或文件。
