我正在尝试使用SpringBoot编写一个简单的RESTful服务。但是，有一条错误消息我无法解决。我一直在研究，它看起来像是SpringBoot版本之间的冲突，但我不确定如何才能摆脱它

我有一个SpringBootApp：

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

/**
 * REST Service application
 */
@SpringBootApplication
public class Application {

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

您可以在pom中更新spring版本吗？或者处理管理maven依赖关系
推荐方法
转到站点并选择web堆栈作为依赖项，如下所示
由于Spring Boot使用了自以为是的依赖项和物料清单的概念，它将自动提取其他依赖项并解决classNotFoundException问题。在您的例子中，它遗漏了Spring-core-4.2.4.RELEASE.jar依赖项
执行Maven目标为cleanstallspringboot:run-e，您可以在IDE中找到您的Maven依赖项，下面给出的是一个示例POM文件
  <?xml version="1.0" encoding="UTF-8"?>

请为您的家长试用此版本我在Spring boot 2.1.9.RELEASE上也遇到了同样的问题

        <relativePath/> <!-- lookup parent from repository -->
    </parent>

使用该机制来避免冲突和重复，从spring批处理依赖关系中取下，右键单击project>maven>update projecrt（强制更新快照）2 maven clean&maven install，然后尝试通过清除~/.m2/存储库目录来克服这一点……谢谢。我添加了它并重建了它，但是它说“缺少工件org.springframework.boot:springbootstarterweb:jar:4.3.2.RELEASE”，您运行得干净吗？我正在检查pom导入—您可以从您的导入中删除核心，只需检查其他导入—您可以删除web依赖项，或者删除版本—然后它们将继承自bomBut，但降级到旧版本很难解决长期存在的问题。你找不到可以与更高版本的spring boot starter一起使用的东西吗？请扩展你的答案。添加其他信息，说明为什么更新到该版本会解决op存在的问题。
