我已经尝试过修改包结构和使用scanBasePackages，但是没有任何改变错误
非常感谢您的帮助。因为当您将Spring Boot starter web
添加到pom文件中时，Spring Boot将自动添加嵌入式Tomcat依赖项作为默认选择。您可以直接将应用程序作为独立的web应用程序运行
正如我在您的问题下的评论中所说，如果您想将WAR文件部署到任何Servlet 3容器中，您需要在spring boot starter web
中排除spring boot starter tomcat
的依赖性
例如：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
org.springframework.boot

回答我自己的问题：
我没有一个完整的解决方案。我遇到了@Olantobi在我的帖子评论中指出的同样的问题。首先，我需要将其添加到我的主类Application.java中，以使其与我的配置一起工作：
@SpringBootApplication(scanBasePackages = "com.test")
这是一个什么样的例子：
要让它运行并部署到localhost，我需要做的另一件事是：
现在可以了。我不确定我是否需要做任何特殊的事情才能让它在AWS elastic beanstalk服务器上运行，但如果需要，我可能会在这里发表评论。这里介绍了解决方案
TLDR从pom.xml文件中的spring boot starter tomcat
的依赖项中删除提供的，我认为这里有一个误解，在spring boot中，我们不需要创建war来部署在tomcat服务器中。使用SpringBoot的优点是它添加了所有必需的依赖项。所以您只需要开发应用程序
以下是您可以尝试使其工作的步骤
若您希望您的项目创建war文件并将其部署到外部服务器中，那个么您需要将spring boot中tomcat依赖项的范围设置为“提供”
`
org.springframework.boot
弹簧启动机tomcat
假如
`
如果您希望在运行spring引导应用程序后自动部署应用程序，请将作用域设置为“compile”
`
org.springframework.boot

`
删除范围：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>provided</scope>
</dependency>
org.springframework.boot

假如
或替换为编译：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>compile</scope>
</dependency>
org.springframework.boot
弹簧起动试验
编译
添加此项解决了我的问题
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<version>2.4.5</version>
</dependency>
org.springframework.boot

2.4.5
这可能是Intellij的一个问题。我在生成WAR文件时没有遇到问题。WAR文件将输出到我的目标文件夹。问题出在Spring本身。一旦添加了Spring boot starter web
的依赖项，您的应用程序将自动成为一个独立的web应用程序，并将嵌入式Tomcat作为默认web容器。@LHCHIN删除它并没有修复任何问题。我想无论如何我都会把它放在那里，因为它可以帮助我记住我使用的依赖项。不幸的是，这不起作用。到目前为止，有效的方法是使用IDE IntelliJ中提供的用于spring引导运行的命令行命令。我将在稍后发布一个答案。对于以下内容：将其部署到AWS Elastic Beanstalk需要我在resources文件夹中创建一个application.properties文件，并将server.port设置为5000。这是AWS将尝试在其上运行应用程序的默认端口，默认端口8080将不起作用。
