Spring boot 示例：无法启动嵌入式容器错误

我是 spring 新手，所以我从 spring intializr 下载了 jar for maven-web java 1.8 demo。我将其提取并导入到 STS 中以运行 main() 文件，但出现以下异常。有人可以告诉我这个问题的解决方案是什么吗？

我从网上尝试过的解决方案但是没用：- 尝试将 Hibernate-validator 依赖项添加到 pom - 尝试将 spring-boot-starter-tomcat 依赖项添加到 pom

@SpringBootApplication
public class DemoApplication {

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

Spring Boot 1.5.9 版本也有同样的问题。 添加到答案中吉姆·凯利 https://stackoverflow.com/a/41879605/1537888，您应该在 Maven pom.xml 中添加以下内容：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>5.3.6.Final</version>
</dependency>

您可以在 Spring Boot pom.xml 文件 (spring-boot-dependency-1.5.9.RELEASE.pom) 的属性部分下使用依赖项版本：

<hibernate-validator.version>5.3.6.Final</hibernate-validator.version>

位于路径下：

/.m2/repository/org/springframework/boot/spring-boot-dependencies/1.5.9.RELEASE/spring-boot-dependencies-1.5.9.RELEASE.pom
