装配WAR时出错：需要webxml属性（如果在更新模式下执行，则为预先存在的WEB-INF / web.xml）

我正在通过http://www.mkyong.com/spring-security/spring-security-hibernate-annotation-example/的引用开发Spring MVC Security Hibernate示例。在此示例中，我将maven依赖项更新为最新版本

<properties>
        <jdk.version>1.8</jdk.version>
        <spring.version>4.2.4.RELEASE</spring.version>
        <spring.security.version>3.2.9.RELEASE</spring.security.version>
        <jstl.version>1.2</jstl.version>
        <mysql.connector.version>5.1.38</mysql.connector.version>
        <logback.version>1.1.2</logback.version>
        <slf4j.version>1.7.6</slf4j.version>
        <hibernate.version>4.2.11.Final</hibernate.version>
        <dbcp.version>1.4</dbcp.version>
    </properties>

参考编译错误：

根据：https://maven.apache.org/plugins/maven-war-plugin/dependency-info.html。您需要添加以下插件：

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.6</version>
    <configuration>
        <failOnMissingWebXml>false</failOnMissingWebXml>
    </configuration>
</plugin>

这将解决问题。
