这是在服务器日志中看到的完整堆栈跟踪:

这是applicationContext.xml文件:

And here is the applicationContext.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context

    <context:component-scan base-package="com.mkyong.common.controller" />
    <mvc:annotation-driven />
</beans>

我已经尝试删除第一行，但仍然遇到相同的错误.

I've already tryed to remove the first line, still got the same error.

这里是我的pom.xml文件(我已经检查过Spring框架的版本):

By the way here is my pom.xml file (I've allready checked spring framework versions):

<properties>
    <spring.version>3.0.5.RELEASE</spring.version>
</properties>
<dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>${spring.version}</version>
    </dependency>
</dependencies>

我尝试重新加载Maven依赖项，并尝试了各种方法(例如，一个空的applicationContext.xml文件)，但是它总是给我同样的错误.该应用程序甚至没有显示在tomcat的管理器中.

I've tryed reloading maven dependencies, tryed with various things (for example an empty applicationContext.xml file) but it always give me the same error.The application doesn't even show up in tomcat's manager.

有人可以指出正确的方向来纠正此错误吗?

Can some point me in the right direction to fix this error?

推荐答案

最后要回答我自己的问题，这是我的特定版本的tomcat的问题.

To finaly answer my own question, it was a problem with my particular version of tomcat.

我只是再次从他们的网站上下载了tomcat，该应用程序开始正常运行.

I simply downloaded tomcat again from their website and the application started flawlessy.

此错误可能是由于我端的损坏的库文件引起的，或此特定版本的tomcat出现了问题.我真的不知道，因为我无法更准确地指出问题出在哪里.

It's possible that this error was coming from a corrupted library file on my end, or something wrong with this particular build of tomcat. I don't really know since I was unable to pinpoint more exactly where the issue is.
