注解配置SpringMVC遇到问题

问题：将WEB-INF下的web.xml删掉后，启动后报错

Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.2:war (default-war) on project springMVC_annoation: Error assembling WAR: webxml attribute is required (or pre-existing WEB-INF/web.xml if executing in update mode)

解决：告诉maven不要找web.xml
在pom.xml中添加

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.6</version>
                <configuration>
                    <failOnMissingWebXml>false</failOnMissingWebXml>
                </configuration>
            </plugin>
        </plugins>
    </build>
