You can look at http://mvnrepository.com/:
你可以看看http://mvnrepository.com/：
http://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-tomcat/1.2.5.RELEASE
http://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-tomcat/1.2.5.RELEASE
Below you have section Compile Dependenciesand you can see that it uses Tomcat 8.0.23.
下面有部分Compile Dependencies，您可以看到它使用Tomcat 8.0.23.

You can also check the version without leaving your IDEby seeing the effective pom.
您还可以通过查看有效的 pom来检查版本，而无需离开您的 IDE。
For example, if you are using IntelliJ you can view effective pom by right clicking pom.xml > Maven > Show effective POM.
例如，如果您使用 IntelliJ，您可以通过右键单击pom.xml > Maven > ShowEffective POM 来查看有效的 pom 。
...or from the command line by issuing mvn help:effective-pom
...或从命令行发出 mvn help:effective-pom

or For Gradle print the dependepency tree via the console with
或者对于 Gradle 通过控制台打印依赖树
./gradlew dependencies
Example snippet from output:
来自输出的示例片段：
...
| +--- org.springframework.boot:spring-boot-starter-tomcat:2.1.0.RELEASE
| | +--- javax.annotation:javax.annotation-api:1.3.2
| | +--- org.apache.tomcat.embed:tomcat-embed-core:9.0.12

In my example above it is tomcat version 9.0.12

I generally keep spring boot tomcat dependency as provided Which means my local tomcat version may be slightly different.
我通常保留 spring boot tomcat 依赖项，这意味着我本地的 tomcat 版本可能略有不同。
The java buildpack includes the tomcat version
java buildpack 包含 tomcat 版本

e.g. java buildpack 4.19.1 comes with Openjdk 1.8.0_212 and tomcat 9.0.19
例如，java buildpack 4.19.1 带有 Openjdk 1.8.0_212 和 tomcat 9.0.19

You can check the versions of all the dependencies in the dependency tree.
您可以在依赖树中查看所有依赖的版本。
for that:
为了那个原因：
- go to the directory of pom.xml
run the following command:
$ mvn dependency:tree

- 进入 pom.xml 目录
运行以下命令：
$ mvn 依赖项：树

And you will be able to watch all the dependencies and versions associated with that dependency.
您将能够查看与该依赖项关联的所有依赖项和版本。

In Eclipse IDE:
在 Eclipse IDE 中：
- Open your pom.xml
- Go to "Effective POM" tab
- Search for "tomcat"
- Find
<tomcat.version>line, for example:<tomcat.version>9.0.27</tomcat.version>
- 打开你的 pom.xml
- 转到“有效 POM”选项卡
- 搜索“tomcat”
- 查找
<tomcat.version>行，例如：<tomcat.version>9.0.27</tomcat.version>
