我使用了spring-io提供的示例gs-convert-jar-to-war。它描述了如何在spring boot项目中生成war包。
spring-boot文档允许使用自己的父pom,因此为所有spring-boot项目省略了预定义的父pom。必须添加以下依赖项:
<dependencyManagement>
<dependencies>
<dependency>
<!-- Import dependency management from Spring Boot -->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.0.1.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>我将此更改(且仅此更改)应用于示例。之后,就不再可能产生战争。我得到以下错误消息:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.1.1:war (default-war) on project gs-convert-jar-to-war: Error assembling WAR: webxml attribute is required (or pre-existing WEB-INF/web.xml if executing in update mode) -> [Help 1]以下是修改后的pom.xml的完整清单:

在我的项目中,我将使用我自己的父pom,因为它定义了很多关于公司的东西。

您删除了父插件,因此丢失了它对WAR插件配置的声明。这就是它:
<plugin>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>源代码请参见here。
注:对于Spring Boot 2.0 parent pom和更高版本( war插件版本不同),或者如果您使用最新的war插件,这是不必要的。
