1.如果WebContent/WEB-INF/web.xml文件存在，需要在pom.xml文件中加上maven-war-plugin插件
<build> <plugins> <!--加上此代码即可--> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>3.0.0</version> <configuration> <webResources> <resource> <directory>WebContent</directory> </resource> </webResources> </configuration> </plugin> </plugins> </build>2.如果web.xml文件不存在，则按下面的方式配置。
<build> <plugins> <!--加上此代码即可--> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>3.0.0</version> <configuration> <failOnMissingWebXml>false</failOnMissingWebXml> </configuration> </plugin> </plugins> </build>成没成功可以看war里面的文件 是不是全的！！
附一张我这边没有web.xml的 成功图
