http://localhost:8080打开tomcat主页的原理是啥

Posted 2023-04-25

为什么http://localhost:8080能打开tomcat主页，原理是什么？
http://localhost:8080/uPortal/表示什么意思

http://localhost:8080/uPortal/ 后面的uPortal表示项目名称。原理简单解释如下：

tomat是一个servlet容器，来处理http请求。在平时的使用中我们都会在浏览器中输入http地址来访问服务资源，比如格式http://localhost:8080。从浏览器到服务端的一次请求都遵循http协议，在网络上其实走仍然是tcp协议，即我们常使用的socket来处理客户端和服务器的交互。根据输入的http地址可以知道服务器的IP地址和端口，根据这两个参数就可以定位到服务器的唯一地址。tomcat根据http地址端口后面的资源路径就可以知道反馈什么样的资源给浏览器。

扩展资料：

Tomcat Server处理一个HTTP请求的过程：

1、用户点击网页内容，请求被发送到本机端口8080，被在那里监听的Coyote HTTP/1.1 Connector获得。 

2、Connector把该请求交给它所在的Service的Engine来处理，并等待Engine的回应。 

3、Engine获得请求localhost/test/index.jsp，匹配所有的虚拟主机Host。 

4、Engine匹配到名为localhost的Host（即使匹配不到也把请求交给该Host处理，因为该Host被定义为该Engine的默认主机），名为localhost的Host获得请求/test/index.jsp，匹配它所拥有的所有的Context。Host匹配到路径为/test的Context（如果匹配不到就把该请求交给路径名为“ ”的Context去处理）。 

5、path=“/test”的Context获得请求/index.jsp，在它的mapping table中寻找出对应的Servlet。Context匹配到URL PATTERN为*.jsp的Servlet,对应于JspServlet类。

6、构造HttpServletRequest对象和HttpServletResponse对象，作为参数调用JspServlet的doGet（）或doPost（）.执行业务逻辑、数据存储等程序。

7、Context把执行完之后的HttpServletResponse对象返回给Host。

8、Host把HttpServletResponse对象返回给Engine。

9、Engine把HttpServletResponse对象返回Connector。 

10、Connector把HttpServletResponse对象返回给客户Browser。

参考技术A 在你的tomcat/webapps下，有一个目录，叫做“ROOT”，这个目录存放tomcat的基本应用，其原理和你放在webapps下的web工程是一样的。htt p : / / l oc a l h os t: 8 0 8 0 通过hosts文件中的解析，将localhost解析为127.0.0.1，所以这个地址即为htt p : // 127.0.0.1: 8080。默认如果端口后面无项目名，那么访问的将是ROOT下的项目，这个可以证明的，将你的web工程替换掉ROOT下的内容，那么刚的URL就会直接访问该工程。
htt p:// l oca lhost:8 080/ u Port al/表示访问本地8080端口的一个叫做“uPortal”门户网站项目，访问会将你带到uPortal项目默认的主页中。本回答被提问者采纳

我的 http://localhost/ 重定向到 www.localhost.com

【问题描述】：

我检查了我的httpd.conf 文件，但没有发现任何东西，请告诉我需要查看的其他区域。

虽然我的其他链接都可以正常工作，比如 --

http://localhost/phpmyadmin/ 或 http://localhost/myprojects/

这就是我的 httpd.conf 文件中的内容 -

DocumentRoot "C:/xampp/htdocs"

#
# Each directory to which Apache has access can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories). 
#
# First, we configure the "default" to be a very restrictive set of 
# features.  
#
<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order deny,allow
    Deny from all
</Directory>

最后--是的我在问之前用谷歌搜索了很多，但在我的情况下找不到任何东西。

Apache 正在工作 --

我的 hhtpd.conf 文件 --

#
# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.2> for detailed information.
# In particular, see 
# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"
# with ServerRoot set to "C:/xampp/apache" will be interpreted by the
# server as "C:/xampp/apache/logs/foo.log".
#
# NOTE: Where filenames are specified, you must use forward slashes
# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").
# If a drive letter is omitted, the drive on which httpd.exe is located
# will be used by default.  It is recommended that you always supply
# an explicit drive letter in absolute paths to avoid confusion.

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to point the LockFile directive
# at a local disk.  If you wish to share the same ServerRoot for multiple
# httpd daemons, you will need to change at least LockFile and PidFile.
#
ServerRoot "C:/xampp/apache"

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 0.0.0.0:80
#Listen [::]:80
Listen 80

【问题讨论】：

那里有任何 .htaccess 吗？在根目录中

@HankyPanky 没有 htaccess 我已经在 C:\xampp\htdocs 下检查过

检查你的代理设置...它应该说本地主机没有代理

你在浏览器中试过localhost吗？

感谢您提出这个重要问题，它对我有用。

【参考方案1】：

通过以下方式为我解决了： 首先我了解我系统中的其他浏览器可以正常使用http://localhost 然后 我清除了我的主浏览器缓存 成功了

....... 当然 Samlam 的回放是让提问者满意的答案 但由于问题标题，我在这里回答了这个问题。 大多数人都和我有同样的问题，他们被提到了这个页面。

【讨论】：

终于！这里同样的问题。它只发生在 Firefox 上。我通过清除“localhost”的缓存数据解决了这个问题。如果您不介意丢失所有缓存数据，您可以简单地清除缓存。

【参考方案2】：

我遇到了同样的问题，请记住在进行更改后清除浏览器缓存。

【参考方案3】：

我知道这是一个很老的问题，但只是针对同样的问题，它突然出现了。这是由于 PHP 代码中的问题，而不是由于 Apache 配置。

我检查了文件/var/log/apache2/error.log（在Linux下，我不知道Windows/Mac的路径），这给了我一个提示：

[2015 年 6 月 20 日星期六 21:49:06.444684] [:error] [pid 24149] [client 127.0.0.1:59150] PHP 致命错误：无法在 /docs/Cedric/ 的写入上下文中使用方法返回值Programmation/PHP/slnslv/src/SLN/RegisterBundle/Controller/MemberController.php第80行，referer：http://localhost/slnslv/web/

使用此指示修复 PHP 中的错误神奇地解决了问题。

不知道一个简单的 PHP 错误如何导致分段错误，这会使浏览器 (Firefox) 猜测正确的域名。

【讨论】：

很高兴看到你为一个老问题付出了努力+1

【参考方案4】：

这里有一篇很好的文章，介绍了 Firefox 的这个有用功能，一旦你解决了问题并且仍然被重定向，它就会变得烦人： 归档在“烦人的事情我一直忘记如何解决……”下：

要禁用此“功能”，请执行以下操作：

Type about:config in the browser bar
Type browser.fixup.alternate.enabled in the search box that appears
Right click on the browser.fixup.alternate.enabled that appears in the filtered list below and choose Toggle to set the value to false

【参考方案5】：

我也面临这个问题。但是我的问题现在已经解决了。我只是禁用了 TeamViewer。因此，该问题背后的原因可能是在同一端口上运行的另一个应用程序。 谢谢@Jibran Kassim。

【参考方案6】：

我遇到了同样的问题，在手动安装的 php、apache 和 mysql 系统上，我所有的浏览器都将 http://localhost/mysite 或 localhost/mysite 重定向到 www.localhost.com/mysite。用 localhost 替换 127.0.0.1 运行良好，这意味着我安装的 W.A.M.P 运行良好。我试图按照萨尔曼的方式解决它，但没有运气。我没有查看 C:\Windows\System32\drivers\etc\hosts 文件，我知道即使是主机文件也没有 127.0.0.1 localhost 条目，这无关紧要，因为它默认内置在系统中。

问题已通过停用我的 avast 防病毒防护罩来解决，这会导致这种异常的浏览器行为。如果您遇到这样的问题，您可以先尝试停用您的防病毒防护罩，然后再跳入任何深入的技术解决方案。

【参考方案7】：

www.localhost.com 看不到本地主机，http://localhost 或127.0.0.1 可以看到

【讨论】：

兄弟这实际上不是问题..三个问题 - 如果我在浏览器中输入 localhost ，它会被重定向到这个 URL -> www.localhost.com 。 Salmam 提供了修复的答案。请查看它以供将来参考。

类型：127.0.0.1；你的浏览器是什么？

这会起作用，但我的问题是为什么它不接受（重定向）locahost？

也许您的浏览器添加了一个并将所有单词重定向到yourword.com 或者您的浏览器无法匹配操作系统或您的浏览器有一个本地“localhost”

【参考方案8】：

您是否有机会使用 chrome？因为 chrome 有时对这类东西不太好，尝试不同的浏览器，如果那二人组没有帮助..

那么您的www 目录中的某处必须有一个.htaccess 文件。

尝试搜索它。这是一个不寻常的文件，它没有名称只是一个扩展名。

尝试搜索%.htaccess

如果这对二人组没有帮助，请转到 C:\Windows\System32\Drivers\etc 并以管理员身份打开文件 hosts，以便您可以对其进行编辑并查看是否有程序在其中插入了一些东西。

刚刚想起我之前遇到的一个情况。一些 .php 文件中可以有重定向。如果他们进行重定向，请检查您的 index.php 或 main.php 或 index.phtml 或其他扩展，因为可能有人编写了代码来重定向脚本。

看这个例子来理解它： WWW to non-WWW Redirect with PHP

感谢您提供更多研究内容 :) 为 chrome 和新内容投票 +1

避免在您的帖子中使用冒犯性的词语。

@Sangoku 我的主机文件看起来不错 -- # localhost 名称解析是在 DNS 本身内处理的。 # 127.0.0.1 本地主机 # ::1 本地主机

您是否尝试搜索 htaccess 文件？现在您排除了路线，这是唯一可能的解释。以防万一尝试您的本地主机的 dns reslove。但我敢打赌，隐藏在某个地方的 htaccess 文件...

@swapnesh 阅读我刚刚所做的编辑，如果没有 htaccess 文件，那么它自己的代码必须重定向他自己。通常的做法是使用 header() 函数从 $__SERVER['forgot the name'] 重定向到 www.$__SERVER['forgot the name']

【参考方案9】：

从您的 cmets 来看，您似乎看错了地方。看this question。

可能安装在根目录（您在键入http://localhost/index.php 时希望看到的那个）中的应用程序配置不正确。找到 index.php 文件在根目录下的应用程序，然后查看它的配置文件，看看是否可以找到写在某处的www.localhost.com。一些应用程序将其设置存储在数据库中，因此这是另一个可以查看的地方。

感谢链接，我将对其进行调查并继续进行此操作..一旦完成..我一定会让您知道当前工作的 +1 :)

终于它的工作了..awesome..你正确地阅读了我的头脑和文字:)是的，这是我的一个zend项目中htaccess的问题..但是没有任何东西www.localhost.com但是在重命名文件时，我成功地使其工作:)
