    解决方法:

    是因为没有添加相应的spring-webmvc包,maven添加或者下载加上即可,如下:

    <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>4.3.11.RELEASE</version>
    </dependency>
     
    <dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    </dependency>

    加上引用即可!

    很明显spring-web的版本问题。。你要找一个版本RequestMapping有name属性的。。
    例如3.0.5没有。。。4.1.3有
