Question

我在使用tomcat8.0启动应用程序（spring + maven）时遇到错误（ClassNotFoundException）。不知道甚至在日志中发生了什么错误。请帮忙

SEVERE: Error configuring application listener of class org.springframework.web.context.ContextLoaderListener

以下是我在web.xml中配置监听器的方法：

<servlet>
    <servlet-name>reporting</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>reporting</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>  
        /WEB-INF/reporting-servlet.xml,  
        /WEB-INF/spring-security.xml,
        /WEB-INF/dao-context.xml
    </param-value>
</context-param>

应用程序工作正常，当我向项目添加新的maven模块时出现问题。现在，即使删除模块也会导致同样的问题。

下面的pom.xml依赖项：

<dependencies>
    <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>

    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-io</artifactId>
        <version>1.3.2</version>
    </dependency>

    <!-- log4j -->
    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>${log4j.version}</version>
    </dependency>

    <!-- Spring Security -->
    <dependency>
        <groupId>commons-httpclient</groupId>
        <artifactId>commons-httpclient</artifactId>
        <version>3.1</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context-support</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.0.1</version>
        <scope>provided</scope>
    </dependency>
</dependencies>

真正的问题似乎是我的pom.xml文件中的jar文件版本。使用相同版本的各种弹簧罐解决了这个问题。这篇文章有助于解决这个问题。 Which maven dependencies to include for spring 3.0?
