在Eclipse中从Spring:boot项目创建war文件

我对Spring Boot还是很陌生，并且已经完成了一个在本地主机上运行良好的应用程序.有人告诉我要将其部署在本地主机之外，例如在webbhotel或simular上，我需要将项目导出为war文件而不是jar文件.

I am pretty new to Spring Boot and I have completed a application that works well on my localhost. As I have been told to deploy it outside my localhost on for example a webbhotel or simular I need to export the project as a war-file and not as a jar-file.

更新！！ 我将项目作为Spring Initialzr中生成的Springproject来运行，并使用Eclipse作为IDE.

UPDATE!! I run the project as a Springproject generated in Spring Initialzr and using Eclipse as a IDE.

在Eclipse中，我已按照步骤

In Eclipse I have followed the steps

<packaging>war</packaging>

和

<dependencies>
    <!-- … -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
    </dependency>
    <!-- … -->
</dependencies>

来自Spring Boot参考页 https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file

from Spring Boot Referencepage https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file

在我的项目中，我使用

<dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
        <scope>provided</scope>
    </dependency>

我是否需要添加sprinng-boot-starter-tomcat依赖项，并在tomcat-embed-jasper上添加该依赖项，以便我的依赖项是这样?

Do I need to add the sprinng-boot-starter-tomcat dependency and add provided to that on aswell as tomcat-embed-jasper so that my dependency will be like this?

<dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
        <scope>provided</scope>
    </dependency>
     <dependency>
    <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
    </dependency>

当我尝试在Eclipse中导出到war文件时，Eclipse找不到我的项目.如果我尝试导出Java> JAR FILE，但如果尝试Web> WAR FILE

When I try to export to war-file in Eclipse, Eclipse can't find my project. It can find it if I try to export Java>JAR FILE but not if I try Web>WAR FILE

有人知道我在做什么错吗?是否有必要导出到WAR文件以部署到外部服务器?

Do anyone know what I am doing wrong and if it is neccesary to export to a WAR-file to deploy to a external server?
