我的web.xml文件存在问题。 我用Web模块版本3.0创建了一个eclipse动态Web项目 默认情况下，我没有自己创建的web.xml文件。

现在，当我尝试运行该项目时，我收到此错误：

我之前在办公室机器上遇到了同样的问题，我可以通过在eclipse中清理服务器来解决这个问题。

现在我已经清理了我的服务器并删除了服务器但结果相同。如果我从web.xml项目运行中删除servlet模块。这就是为什么我猜测问题是servlet映射，但我看不出错误。

我的Web.xml：

  <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>AJAX_J2EE</display-name>
  <welcome-file-list>
    <welcome-file>/pages/index.html</welcome-file>    
  </welcome-file-list>
  <servlet>
    <display-name>testController</display-name>
    <servlet-name>testController</servlet-name>
    <servlet-class>servlet.testController</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>testController</servlet-name>
    <url-pattern>/testController</url-pattern>
  </servlet-mapping>
  </web-app>

感谢任何帮助。在此先感谢：）

答案 0 :(得分：3)

在pom.xml中你错过了在servlet的依赖中编写（<scope>provided</scope>）所以在servlet的依赖下你只需要在pom.xml中添加（<scope>provided</scope>） 例如<dependency>
    <groupId>javax.servlet</groupId>     
<artifactId>jsp-api</artifactId>     
<version>2.0</version>
<scope>provided</scope>
</dependency>
＆＃34;或＆＃34; <dependency>     
<groupId>servletapi</groupId>
    <artifactId>servletapi</artifactId>     
<version>2.4</version>
<scope>provided</scope>
</dependency> 这个解决方案对我有用。

谢谢

我从here发现了我的错误。

我使用“Create Servlet”向导创建了Servlet，该向导添加了@WebServlet（/ servletName）注释，web.xml中没有条目

然后我手动在web.xml中创建了一个条目，该条目在运行时复制了条目。

所以你必须使用Servlet 3.0来完成其中任何一个。

  1. 使用注释，如：

    @WebServlet("/testController")
public class testController extends HttpServlet {    }

    或者

  2. 为您的servlet创建一个web.xml条目。

    3. 了解详情：Servlet 3.0 Annotations
