Spring Boot 不在外部 tomcat 上運行
我以前在 Java 1.8 和 Tomcat 8 上使用過 Spring Boot。我最近開始了一個新專案，我升級到 Java 17，Tomcat 10。
我正在嘗試部署為在外部 tomcat 中運行的戰爭，但它不起作用。
我在實際生產環境現有的Java 1.8和Tomcat 8上運行部署專案沒有任何問題。我想你知道如何部署 spring boot 作為戰爭。
我已經閱讀了下面鏈接中的 Spring Boot 官方檔案。 https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto.traditional-deployment.war
我專案的 pom.xml 應用了以下設定。
<packaging>war</packaging>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
和
<configuration>
<mainClass>mypackage.SpringBootCoreApplication</mainClass>
</configuration>
并且SpringBootApplication也配置好了。
@SpringBootApplication
public class SpringBootCoreApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SpringBootCoreApplication.class);
}
public static void main(String[] args) {
SpringApplication.run(SpringBootCoreApplication.class, args);
}
}
現在，我運行 Tomcat 部署為戰爭，并出現以下日志。

我記得 Spring Boot 不會以這樣的日志結尾。該專案正在運行，但 spring boot 似乎沒有運行。
日志顯示連接成功，但實際上并沒有連接上。
看了Spring Boot官方檔案，很多問答，博文，都解決不了。
我不知道我配置錯了什么。請幫我
uj5u.com熱心網友回復：
我找到了原因。我寫這篇文章是為了那些因為同樣的原因而苦苦掙扎的人。
升級到 Tomcat 10 是個問題。
Tomcat10 是目前不支持的 JakartaEE 規范的實作。Spring（和 Spring Boot）目前只支持 JavaEE，不支持 JakartaEE。計劃在今年晚些時候為 Spring6 和 SpringBoot3 提供 Jakarta EE 支持。
有兩種選擇。
- 將war部署到
webapps-javaee目錄而不是webapps目錄。Tomcat 使用轉換工具自動轉換。我用這個解決了同樣的問題。 - 使用支持 Java EE 的 Tomcat 9
