java - Java Webapp 在 Eclipse 中运行良好，但在 Tomcat 中运行良好

Question

我有一个小的 Java/Spring MVC REST /Maven 应用程序，它在 Eclipse 中运行得很好，而且当我从提示符运行以下命令时：

mvn clean tomcat6:run

我的问题是当我这样做时：

mvn 清洁包

并将生成的war文件推送到我的独立Tomcat实例中的“webapps”文件夹中，该服务不再工作。

独立的 Tomcat 启动得很好，日志中没有错误。有趣的是，当我在 Eclipse 中或通过 mvn 命令运行应用程序时，独立实例在端口 8989 和 8080 上进行侦听。

一旦应用程序在独立的 Tomcat 中启动，如果我尝试使用 RESTClient 访问我的服务，我会返回 404。我的自定义 404 实际上，不是通用的。

像我的 index.html 这样的静态内容也很好。

这是我的 web.xml 文件：

    <?xml version="1.0" encoding="ISO-8859-1"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  <error-page>
    <error-code>404</error-code>
    <location>/WEB-INF/404.htm</location>
  </error-page>
</web-app>

还有臭鼬-servlet.xml：

该配置中是否有任何内容可以解释为什么对调度程序 servlet 的任何请求都返回 404 而不是路由到控制器？

谢谢

更新：

从 Tomcat Standalone 添加日志输出。

如果您只是复制yourproject.war到 Tomcat 的webapps文件夹并让默认部署程序启动（扩展yourproject.war为名为的目录yourproject），那么您应该知道默认的 Tomcat 逻辑是使您的应用程序在/yourproject.

如果您希望应用程序在根上下文 ( ) 下可用，/则应适当配置 Tomcat。

所以这是你的组合。

App - Environment Status
Eclipse->Working
Eclipse Embedded TOMCAT -> working
Standalone TOMCAT -> Not working

查看 Eclipse Tomcat 首选项，它可能添加了类路径和库路径，这将使 Tomcat 能够识别。过去也遇到过类似的问题。

此外，您的静态内容也可以正常工作。这意味着 Eclipse 类路径中存在一些要运行的重要 jar，这在独立 Tomcat 中不可见。

干杯

弄清楚了。我不得不从这里更改 web.xml 中的 servlet 映射：

  <servlet-mapping>
    <servlet-name>skunk</servlet-name>
    <url-pattern>/skunk/*</url-pattern>
  </servlet-mapping>

对此：

  <servlet-mapping>
    <servlet-name>skunk</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>

为了能够使用 url 访问服务：

http://localhost:8080/skunk/myService

我在那里的原始映射意味着我必须输入：

http://localhost:8080/skunk/skunk/myService

为我服务……叹息

感谢你们！
