使用Maven3 Eclipse 7 Tomcat 7出现404错误的WebServlet

Question

我的项目命名为“A”，我的类是：

@webservlet(urlpatterns={“/test/*”}）公共类RequestHandler扩展了HttpServlet{

Maven插件：

<plugin>
      <groupId>org.apache.tomcat.maven</groupId>
      <artifactId>tomcat7-maven-plugin</artifactId>
      </plugin>

在src/main/webapp/WEB-INF/web.xml下，我有

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"/>

Running war on http://localhost:8080/A

我做错了什么？

Answer 1

删除web.xml文件。

使用以下内容配置pom.xml：

<build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
