问题描述

限时删除！！

我创建了一个基于

，并尝试从Eclipse中运行它，因为Tomcat 7已配置为在127.0.0.1上运行，但是我得到页面找不到在127.0.0.1/helloworld/HelloWorld

我也尝试导出为war文件并将其部署到（否则工作）Tomcat服务器作为Windows服务运行，并与Tomcat Application Manager - manifest.mf一起部署，这些类很好地复制到tomcat / webapps / helloworld，但是尝试导航到127.0.0.1/helloworld/HelloWorld再次失败，显示 HTTP状态404

I created a test project based on Tomcat HelloWorld Servlet with Eclipse
and tried to run it from Eclipse as is with Tomcat 7, which I have configured to run on 127.0.0.1 - but I get Page cannot be found at 127.0.0.1/helloworld/HelloWorld
I also tried exporting as war file and deploying it to the (otherwise working) Tomcat server running as a Windows service - and deployed with the Tomcat Application Manager - manifest.mf and the classes are nicely copied to tomcat/webapps/helloworld, but trying to navigate to 127.0.0.1/helloworld/HelloWorld fails again, showing HTTP Status 404

从默认的@WebServlet到web.xml配置

接下来，在HelloWorld.java中，我尝试注释

From default @WebServlet to web.xml configuration

Next, in HelloWorld.java, I tried commenting out

//@WebServlet("/HelloWorld")

和t添加一个web应用程序特定的web.xml配置：

and then adding a web-application-specific web.xml configuration:

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

但结果仍然相同 - 无回复！

But the results are still the same - no response!

给定链接教程提供了Tomcat 6的说明，我应该更改某些内容以使其与Tomcat 7配合使用？

具体来说，Eclipse添加的默认值为$ code> @WebServlet（/ HelloWorld） Servlet 3.0的注释配置需要什么（不需要web.xml）？

或者是阻止在全局tomcat服务器级别的任何Web应用程序部署？我已经改变了服务器配置有点，不幸的是我不记得什么，除了使它服务于127.0.0.1而不是127.0.0.1:8080

Given the linked tutorial provides instructions for Tomcat 6, should I change something to make it work with Tomcat 7?
Specifically, is the default @WebServlet("/HelloWorld") added by Eclipse sufficient? What is needed for the annotation-based configuration of Servlet 3.0 to work (without web.xml)?
Or could it be that something is blocking any web app deployment at the global tomcat server level? I have changed the server configuration somewhat, and unfortunately i do not remember exactly what, except for making it serve on 127.0.0.1 rather than 127.0.0.1:8080
