报错原因：
原因:找不到web.xml,但是项目中明明有这个文件,在WebContent/WEB-INF/文件夹下,就是识别不了
解决方法：
需要在pom.xml文件中,加上maven-war-plugin插件配置
在<build>节点中增加:
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.4</version>
<configuration>
<webResources>
<resource>
<directory>WebContent</directory>
</resource>
</webResources>
</configuration>
</plugin>
</plugins>
如果项目中原本没有web.xml文件,就需要加上下面的配置:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.4</version>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
</plugins>
</build>
