java - Apache 错误: "FAIL - Application at context path/tibclient could not be started"

Question

我正在尝试通过 Apache Tomcat 6.0 部署我的 Maven 项目。我能够使用 mvn tomcat:deploy 从命令提示符成功部署它。当我尝试访问我的应用程序时，它在网页上出现 404 错误。

在我的 tomcat 管理器中，我可以看到有一个选项“启动应用程序”，当点击“开始”时，它会给我“失败 - 上下文路径/tibclient 处的应用程序无法启动”消息。

我正在使用 Eclipse，我不清楚如何通过 apache tomcat 部署 Maven 项目。任何帮助表示赞赏。谢谢

我的web.xml如下:

Answer 1

javax.servlet-api API 的依赖项应在provided 的范围内。 Servlet API 已包含在 TomCat 中。将其包含在您的 Web 应用程序中将导致类加载错误，因为由于 ClassLoader 限制，您的 WAR 中的版本和 TomCat 中的版本“不相同”。

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <!-- The Servlet API is provided by Tomcat -->
    <scope>provided</scope>
</dependency>
