ClassNotFoundException :: org.springframework.web.context.ContextLoaderListener答案

【问题描述】：

运行 Spring web maven 项目时出现以下错误

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

在我将另一个项目导入 Eclipse 之前，该项目工作正常。

我尝试了网络中的所有解决方案（部署程序集、Tomcat 库类路径、清理 Tomcat 工作目录、maven-compiler-plugin 版本）。

但是当我导出战争文件并将其上传到云端（jelastic）时，它工作正常！

这里是 pom.xml

【问题讨论】：

看起来你的项目/tomcat 的类路径中缺少 spring-web.jar
@EiasO 在你的问题中添加你的 pom.xml
@Skizzo 我已经添加了它
没有 jar 丢失！你的 pom.xml 没问题，你也说打包的时候效果很好，那么，你是怎么跑你的项目的呢？在IDE中？我认为这是由您的 IDE 或 CMD 环境引起的。
@LaurenceGeng 我使用 Eclipse(Spring Tool Suite)

标签： eclipse spring maven tomcat pom.xml

【解决方案1】：

在您的 pom.xml 中添加以下依赖项

<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>${org.springframework-version}</version>
</dependency>

更新 1

在你的 pom.xml 中也添加这个

 <!-- To launch embded jetty server -->
    <plugin>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>jetty-maven-plugin</artifactId>
        <version>${maven-jetty-plugin.version}</version>
    </plugin>

并使用 mvn jetty:run 运行您的应用程序，看看问题是否仍然存在

【讨论】：

@EiasO 如何在tomcat中部署？您在部署应用程序时是否检查过该 jar 是否在您的类路径中？
是的，我打开了部署位置，jar 已经在那里
严重：PWC6117：找不到文件“/src/main/webapp/CWEB-INF/views/home.jsp”
@EiasO 这是另一个问题，尝试用这个SEVERE: PWC6117: File not found - Jetty得到解决方案

【解决方案2】：

添加到你的 pom.xml

<dependency>
 <groupId>com.fasterxml.jackson.core</groupId>
 <artifactId>jackson-databind</artifactId>
</dependency>
