我有一个 spring boot 项目，我正在尝试使用嵌入式 Tomcat 10 而不是 Tomcat 7.我将以下内容添加到我的 POM 中...

I have a spring boot project and I am trying to use Tomcat 10 embedded instead of Tomcat 7. I add the following to my POM...

<properties>
    <tomcat.version>10.0.5</tomcat.version>
    ...
</properties>

然后我运行我之前运行的相同命令......

Then I run the same command I was running before...

mvn clean package -U && java -cp target\my.jar;props -Dloader.main=com.my.Main org.springframework.boot.loader.PropertiesLauncher

但现在它只是启动然后自行关闭.最后的消息是...

But now it just starts and then shuts itself down. The final messages are...

2021-05-13 15:35:42.105  INFO 10084 --- [           main] com.my.Main                   : Started Main in 42.918 seconds (JVM running for 44.009)

推荐答案

Tomcat 10 是 Jakarta EE 9 servlet 容器.这基本上意味着，出于版权原因，所有 javax.* 包都被重命名为 jakarta.*(Oracle 不允许 Eclipse 基金会使用 javax.*).* 名称).

Tomcat 10 is a Jakarta EE 9 servlet container. It basically means, that all javax.* packages were renamed to jakarta.* for copyright reasons (Oracle didn't allow the Eclipse Foundation to use the javax.* names).

Spring Boot 2 和 Spring 5 仅支持之前的 Java EE 8 规范，Tomcat 10 支持需要等待 Spring Boot 3 和 Spring 6.或者，您可以通过 Apache Tomcat Migration Tool 传递 Spring 库，该工具刚刚达到 1.0 版或降级到Tomcat 9.0.

Spring Boot 2 and Spring 5 support only the previous Java EE 8 specification, you need to wait for Spring Boot 3 and Spring 6 for Tomcat 10 support. Alternatively you can pass Spring libraries through the Apache Tomcat Migration Tool, which just reached version 1.0 or downgrade to Tomcat 9.0.

Tomcat 10.0.4 无法加载 servlet(@WebServlet 类)并出现 404 错误
