我试图在我的机器上运行一个小型基本的Spring Bootstrap ，当我在maven上运行clean compile（甚至在尝试spring-boot：run之前）时，我得到以下错误：

下面是我的Pom.xml：

下面是我的java类：

package com.benayed.spboot.poc.SpringBootPoc;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringBootPocApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootPocApplication.class, args);
    }

}

我尝试了许多解决方案，我可以找到互联网上，如删除.m2存储库，添加不同的标签（版本，分支，...）到spring-boot-maven-plugin插件，我很肯定，这是造成问题的一部分
有什么建议吗？

您需要添加此依赖项

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

那它就会起作用。

你有0个编译依赖项，只定义了测试-编译依赖项，因为你已经注解掉了spring-boot-starter-data-jpa。Spring starter会拉入其他依赖项（包括其他starter）以创建编译时所需的一切。取消注解spring-boot-starter-data-jpa依赖项，和/或重新评估你实际需要的依赖项。

1)关闭项目2）再次导入项目并选中自动导入
这对我有用，也许对你也有用

如果项目的.mvn文件夹中存在任何Wrapper文件夹，请将其删除。另外，转到文件-〉设置-〉构建、执行、部署-〉BuildTools-〉Maven-〉将Maven主路径设置为捆绑（Maven 3）

在依赖项管理之外添加以下部分，并更新项目。然后是maven的干净安装。

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.10.RELEASE</version>
    </parent>

和下面的依赖关系。

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

如果未修复（不太可能发生），则添加提到的其他依赖项here

如果您不需要与Web相关的库，您可以添加此依赖项，而不是其他答案中提到的spring-boot-starter-web：

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>
