spring boot war without tomcat embedded
提问by niels
I want to create a war file without embedded tomcat with maven. Here the relevant part of my pom
我想用maven创建一个没有嵌入tomcat的war文件。这是我的 pom 的相关部分

How ever if I run mvn package I get a war, where the tomcat*.jar are in a provided-lib folder but still in the lib-folder. I read build-tool-plugins-maven-packaging, but can't find what's wrong.
如果我运行 mvn package 我得到了一场War，其中 tomcat*.jar 在提供的 lib 文件夹中，但仍在 lib 文件夹中。我阅读了build-tool-plugins-maven-packaging，但找不到问题所在。
I know a main idea is to run it as an application, how ever our customer want's to deploy it on his application-server.
我知道一个主要的想法是将它作为一个应用程序运行，我们的客户希望如何将它部署在他的应用程序服务器上。

Following the Hint from M. Deinum I excluded the tomcat-depedency.
按照 M. Deinum 的提示，我排除了 tomcat 依赖。
With the following pom.xml (relevant snippet) a maven clean packagehas the result I want to get.
使用以下 pom.xml（相关代码段）amaven clean package得到了我想要的结果。

I'm not sure if that's the spring-boot way of doing it, but you can exclude the tomcat jars using the maven-war-pluginconfiguration. That is, add the following to your pom.xml:
我不确定这是否是 spring-boot 的做法，但您可以使用maven-war-plugin配置排除 tomcat jar 。也就是说，将以下内容添加到您的 pom.xml 中：
<build>
<plugins>
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.4</version>
<configuration>
<packagingExcludes>WEB-INF/lib/tomcat-*.jar</packagingExcludes>
</configuration>
</plugin>
</plugins>
</build>
Using this approach, the war generated is not executable (cannot be run on command line using java -jar ) but can only be deployed to any servlet container
使用这种方法，生成的War是不可执行的（不能使用 java -jar 在命令行上运行），而只能部署到任何 servlet 容器

I had this same need but removing the mentioned dependency didn't worked. I was able to get the WAR file by adding this <packaging>war</packaging>dependency to my pom file.
我有同样的需求，但删除提到的依赖项没有用。我能够通过将此<packaging>war</packaging>依赖项添加到我的 pom 文件来获取 WAR文件。

I think that the easiest way to build a final WAR from your existing Spring Boot project without embedded Tomcat is the following:
我认为在没有嵌入式 Tomcat 的情况下从现有的 Spring Boot 项目构建最终 WAR 的最简单方法如下：
1) Set WARpackaging for your artifact: <packaging>war</packaging>
1) 为您的工件设置 WARpackaging： <packaging>war</packaging>
2) Set the Tomcat Server dependency to provide:
2）设置Tomcat Server依赖提供：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
If some of your existing Spring Boot dependencies contain it by default, just exclude it. Example:
如果您现有的一些 Spring Boot 依赖项默认包含它，只需排除它。例子：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
That is it.
这就对了。
