java - Maven项目: The hierarchy of the type SpittrWebAppInitializer is inconsistent

Question

我正在使用eclipse来实现《Spring In Action》一书中的代码。

package spittr.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
import org.springframework.web.servlet.support.AbstractDispatcherServletInitializer;

public class SpittrWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer{

}

然后我有一个这样的错误:

    "The hierarchy of the type SpittrWebAppInitializer is inconsistent"

但是我已经在库中导入了必要的类: Click here to see the Maven Dependencies

Maven 和 SpringMVC 对我来说是新的，我对此错误感到困惑，请帮助我。

我觉得你的spring jar包版本比较乱。

你的图片中，spring的版本是2.5.6。但是spring-mvc的版本是3.2.1。

尝试将spring更新到最新版本，我的pom.xml中有关于spring的部分。
