问题与ContextLoaderListener [英] Issue with ContextLoaderListener

问题描述

使用tomcat8.0启动我的应用程序（spring + maven）时，我会收到以下错误（ClassNotFoundException）。
没有线索即使在日志中也会发生什么错误。请帮助

I am getting below errors (ClassNotFoundException) while starting my application (spring+maven) using tomcat8.0. There is no clue what happens wrong even in logs. Please help out

以下是我在web.xml中配置监听器的方式：

Below is how I configured listener in web.xml:

<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>

应用程序运行正常，当我将新的maven模块添加到项目时，会出现问题。现在甚至删除模块也造成同样的问题。

Application was working fine, issue arises when I added a new maven module to the project. Now even removing the module is causing the same problem.

pom.xml依赖关系如下：

pom.xml dependencies below:

<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>

推荐答案

真正的问题似乎是与版本的jar文件在我的pom.xml文件。
使用相同版本的各种弹簧解决问题。
这篇文章有助于解决问题。
春季3.0中包含哪些maven依赖项？ / a>

Real issue seems to be with version of jar files I have in my pom.xml file. Using same version of various spring jars resolved the issue. This post was helpful in resolving the issue. Which maven dependencies to include for spring 3.0?
