我有一个使用 struts2 和 spring 3 的 Web 应用程序。为了配置 spring，我使用 eclipse 和 tomcat 中的构建路径在项目中添加了所需的库。我也在 web.xml 中添加了监听器，但是当我想运行应用程序时，会出现此错误：严重：配置类 org.springframework.web.context.ContextLoaderListener java.lang.ClassNotFoundException: org.springframework.web 的应用程序监听器时出错.context.ContextLoaderListener 我用谷歌搜索太多但什么也没发生..有人告诉我一定要在应用程序库和 tomacat 中添加 spring-web.jar，但没有任何变化..请帮忙

org.springframework.web.context.ContextLoaderListener java.lang.ClassNotFoundException 当 eclipse 不正确地将应用程序发布到 tomcat 服务器时，我经常遇到这个问题（这经常发生在我一天中第一次启动 eclipse 或在一些更大的 svn checkout 之后）

在我的情况下，它有助于执行一系列操作（并始终等待下一步，直到前一步完成！）

  • 首先刷新项目（F5），然后
  • 有一个干净的项目构建（项目/清洁），
  • 再次刷新项目 (F5)，然后
  • 清理服务器
  • 将项目发布到服务器

我建议使用 maven 而不是手动摆弄 eclipse 类路径，如果您可以这样做的话。以下是您可以遵循的简单步骤：

mvn archetype:generate -DgroupId=com.test -DartifactId=test -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

这将生成所需的 Maven 项目结构。然后编辑 pom.xml 文件，如下所示。

<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <finalName>test</finalName>
  </build>
</project>

构建项目：

mvn clean package

并生成eclipse配置源文件：

mvn eclipse:eclipse -DdownloadSources=true

这些步骤足以创建项目结构，该结构在类路径中具有所需的库并附加了源代码。

最后，您可以在 Eclipse 中导入项目。

File > Import > General > Existing project into Workspace > Select the project directory

您可以从http://maven.apache.org/download.cgi下载并安装 maven

我看到你使用 eclipse wtp 插件来运行 web 应用程序，然后你可以在文件系统中找到扩展 web 应用程序，并检查 lib 目录有 spring.jar，你也可以看到这个我的应用程序没有看到 ContextLoaderListener
