关于maven tomcat启动错误

maven(命令为 clean tomcat7:run)启动tomcat提示错误:
org.springframework.web.SpringServletContainerInitializer cannot be cast to javax.servlet.ServletContainerInitializer

自己认为是版本冲突问题,但是不知道怎么解决。
查了下,有人说是pom.xml中servlet jar包部分的<scope/>应该设为provided,但自己确实是这么配置的。
下面是pom.xml部分内容:

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jsp-api</artifactId>
    <scope>provided</scope>
</dependency>

各位有谁遇到过或者对此有个人见解,麻烦给予点拨,谢谢!


----------------------Update-------------------------
排错能力实在有限,还是没能解决问题。
贴一下比较完整的信息吧:

  • 这是启动时的错误信息:

Caused by: java.lang.ClassCastException: org.springframework.web.SpringServletContainerInitializer cannot be cast to javax.servlet.ServletContainerInitializer
    at org.apache.catalina.startup.ContextConfig.getServletContainerInitializer(ContextConfig.java:1670)
    at org.apache.catalina.startup.ContextConfig.getServletContainerInitializers(ContextConfig.java:1652)
    at org.apache.catalina.startup.ContextConfig.processServletContainerInitializers(ContextConfig.java:1562)
    at org.apache.catalina.startup.ContextConfig.webConfig(ContextConfig.java:1270)
    at org.apache.catalina.startup.ContextConfig.configureStart(ContextConfig.java:878)
    at org.apache.catalina.startup.ContextConfig.lifecycleEvent(ContextConfig.java:376)
    at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:119)
    at org.apache.catalina.util.LifecycleBase.fireLifecycleEvent(LifecycleBase.java:90)
    at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5322)
    at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150)
    ... 6 more

根据以上信息我猜测是tomcat本身的api和springframework.web包有冲突(spring版本4.2.4.RELEASE)
spring-web含有一个javax.servlet-api的依赖:

<dependency>
   <groupId>javax.servlet</groupId>
   <artifactId>javax.servlet-api</artifactId>
   <version>3.0.1</version>
   <scope>provided</scope>
</dependency>

自己pom.xml配置的servlet是

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>${servlet-api.version}</version> <!--引用2.5-->
    <scope>provided</scope>
</dependency>            
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jsp-api</artifactId>
    <version>${jsp-api.version}</version>  <!--引用2.0-->
    <scope>provided</scope>
</dependency>

tomcat使用的是:

<groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <configuration>
    <path>/</path>
    <port>8080</port>
</configuration>

本来想换tomcat8试试的,但是好像也没有tomcat8-maven-plugin
试过不包含其它jar包也还是如此,所以该如何是好呢?(╥╯^╰╥)

指定下 Servlet API 的版本试试看:

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jsp-api</artifactId>
    <version>2.0</version>
    <scope>provided</scope>
</dependency>
