我尝试使用 eclipse 和 maven 作为依赖解析器部署 Web 应用程序。但我看到了例外：

我找到了解决这个问题的方法：JBOSS 7 - Spring ContextLoaderListener ClassNotFoundException

这很奇怪，因为..

理论上这个问题已经解决了，但是昨天我在同一台服务器上开发了同样的应用程序，使用同样的设置，并且使用 maven 获取了同样的 jar，没有任何异常。

我想问如何在没有复制.jar文件的情况下解决问题。以及如何在没有手动（显式）用户干预的情况下自动执行此操作。

我只想做：

  • 创建项目
  • 使用 m2e 解决依赖关系
  • jboss并在使用时部署run

您需要调查 java 类路径。当您的应用程序请求它们时，这些类必须可供类加载器加载。

通常对于 Web 应用程序，这意味着需要将包含类的 jar 打包到 WAR 的 /WEB-INF/lib 目录中。

使用 Maven，您应该使用包装类型war，而不是jar。然后maven的war插件（即http://maven.apache.org/plugins/maven-war-plugin/usage.html）会自动将所有依赖打包到war的lib文件夹中。

要使用 m2e 解决依赖关系，您应该

  • 确保项目使用 maven 从命令行编译和打包
  • 从eclipse中删除项目（不要删除文件）
  • 删除 Eclipse 元数据文件（即 .project、.classpath、.settings）
  • 打开日食
  • 导入 --> 导入现有的 Maven 项目 --> 选择你的项目

此时 m2e 将为您创建所有 eclipse 设置，包括动态类路径库。
