我是Spring Boot的新手。只是按照官方网站上的Spring Boot教程构建了一个Spring Boot示例，然后以WAR格式部署在Tomcat上，开始运行时出现以下错误：

有人可以帮忙吗？感谢您的帮助。

PS：代码文件列表为：

Greeting.java
GreetingController.java
SpringBootWebApplicationTest.java
under the same folder named "hello"

配置代码如下：

package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class SpringBootWebApplicationTest extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringBootWebApplicationTest.class);
    }

    public static void main(String[] args) throws Exception {
        System.out.println("Hello World! in main");
        SpringApplication.run(SpringBootWebApplicationTest.class, args);
    }

}

@Ron，在您的pom文件中，您要覆盖与您使用的spring-boot版本不兼容的spring依赖版本，需要让spring-boot导入的是预定义的spring依赖版本。以下是pom中需要更改的相关部分：

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.version>6.2.0.0-SNAPSHOT</project.version>
    <springfox-swagger2.version>2.6.1</springfox-swagger2.version>
    <org.apache.directory.api.api-all.version>1.0.0-M28</org.apache.directory.api.api-all.version>
<!-- REMOVE THIS <spring.framework.version>4.2.4.RELEASE</spring.framework.version> -->
    <spring.boot.version>1.5.1.RELEASE</spring.boot.version>
<!-- REMOVE THIS <spring.version>4.2.4.RELEASE</spring.version> -->
     <start-class>hello.SpringBootWebApplicationTest</start-class>
</properties>
