org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat at org.springframe

根据提供的引用内容来看，问题出现在启动嵌入式Tomcat时。错误信息是"org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat"。原因是在应用程序的依赖中引用了Jackson相关的包，但是没有引用完整。你可以通过添加完整的依赖来解决这个问题。解决方案中提到添加以下依赖：

<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-databind</artifactId>
  <version>2.13.3</version>
  <scope>compile</scope>
</dependency>

同时，你还需要在这个依赖中添加排除规则，以防止冲突：

<exclusions>
  <exclusion>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
  </exclusion>
</exclusions>

另外，还需要添加Jackson Annotations的依赖：

<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-annotations</artifactId>
  <version>2.9.8</version>
</dependency>

这样就可以解决引起Tomcat启动失败的问题了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
