tomcat配置重定向
 

  

  

 
 
Secured Socket Layer (SSL) is the cryptography protocol to provide message security over the Internet. It works on the notion of Private and Public keys and messages are encrypted before sending it over the network.
 
 安全套接字层（SSL）是用于通过Internet提供消息安全性的加密协议。 它适用于私钥和公钥的概念，并且消息在通过网络发送之前已加密。 
 
 
To configure SSL on Tomcat, we need a digital certificate that can be created using Java keytool for the development environment. For the production environment, you should get the digital certificate from SSL certificate providers, for example, Verisign, Entrust, Lets’ Encrypt.
 
 要在Tomcat上配置SSL，我们需要一个数字证书，可以使用Java keytool为开发环境创建一个数字证书。 对于生产环境，您应该从SSL证书提供者那里获得数字证书，例如Verisign，Entrust和Lets'Encrypt。 
 
 

 
 
 
 创建SSL证书 (Creating SSL Certificate)
 
 
Follow the below steps to create your own digital certificate.
 
 请按照以下步骤创建自己的数字证书。 
 
 
$ keytool -genkey -alias tomcat -keyalg RSA -keystore mycertificate.cert
Enter keystore password:
Re-enter new password:
What is your first and last name?
  [Unknown]:  Pankaj Kumar
What is the name of your organizational unit?
  [Unknown]:  Dev
What is the name of your organization?
  [Unknown]:  JournalDev
What is the name of your City or Locality?
  [Unknown]:  Bangalore
What is the name of your State or Province?
  [Unknown]:  Karnataka
What is the two-letter country code for this unit?
  [Unknown]:  IN
Is CN=Pankaj Kumar, OU=Dev, O=JournalDev, L=Bangalore, ST=Karnataka, C=IN correct?
  [no]:  Yes

Enter key password for <tomcat>
	(RETURN if same as keystore password):
Re-enter new password:
$ ls
mycertificate.cert
 
I have used the password “changeit” for Keystore and key but you can use whatever you want.
 
 我已经为密钥库和密钥使用了密码“ changeit”，但是您可以使用任何您想使用的东西。 
 
 
Now our digital certificate is ready and the next step is to enable HTTPS communication port in Tomcat and set it to use our digital certificate for providing SSL support.
 
 现在我们的数字证书已准备就绪，下一步是在Tomcat中启用HTTPS通信端口，并将其设置为使用我们的数字证书提供SSL支持。 
 
 
 Tomcat HTTPS (Tomcat HTTPS)
 
 
To enable SSL open ~Tomcat_Installation/conf/server.xml file and uncomment following line:
 
 要启用SSL，请打开~Tomcat_Installation/conf/server.xml文件并取消注释以下行： 
 
 

  

  

 
 

  

  

 
 
<Connector port="8443" maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" disableUploadTimeout="true"
               acceptCount="100" scheme="https" secure="true"
               keystoreFile="/Users/Pankaj/tomcat/conf/mycertificate.cert"
	       clientAuth="false" sslProtocol="TLS" />
 
To avoid any misplacement of the certificate, I have put that in the tomcat conf directory. Now restart Tomcat and try to access any web application over https with port 8443.
 
 为了避免证书放错地方，我将其放在了tomcat conf目录中。 现在，重新启动Tomcat，并尝试使用端口8443通过https访问任何Web应用程序。 
 
 
 Tomcat重定向HTTP到HTTPS (Tomcat Redirect HTTP to HTTPS)
 
 
So we can access any web application on both HTTP and HTTPS ports. We can set up tomcat to redirect all HTTP request to HTTPS port with some configurations.
 
 因此，我们可以在HTTP和HTTPS端口上访问任何Web应用程序。 我们可以设置tomcat以通过一些配置将所有HTTP请求重定向到HTTPS端口。 
 
 
In ~TomcatInstallation/conf/server.xmlFor HTTP Connector, set the redirect port to the HTTPS connector port. It will look somewhat like this:
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
    <Connector port="8090" maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="8443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true" />
</pre>
</li>
<li>In ~TomcatInstallation/conf/web.xml

Add below configuration but make sure to add it after all the servlet-mapping tags.

<pre>
<!-- added by Pankaj for automatic redirect from HTTP to HTTPS -->
<security-constraint>
<web-resource-collection>
<web-resource-name>Entire Application</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
 在~TomcatInstallation/conf/server.xml对于HTTP连接器，将重定向端口设置为HTTPS连接器端口。 看起来会像这样： 
 
Restart the tomcat now and all the HTTP requests will automatically be redirected to HTTPS i.e https://localhost:8080/axis2 will be automatically redirected to https://localhost:8443/axis2
 
 立即重新启动tomcat，所有HTTP请求将自动重定向到HTTPS，即https：// localhost：8080 / axis2将自动重定向到https：// localhost：8443 / axis2 
 
 
Note: If you don’t want to provide ports in the URLs, then use 80 for HTTP and 443 for HTTPS. In that case, you can skip the first step to automatically redirect HTTP requests to HTTPS because it will automatically pick the default port 443.
 
 注意 ：如果您不想在URL中提供端口，则对HTTP使用80，对HTTPS使用443。 在这种情况下，您可以跳过第一步以将HTTP请求自动重定向到HTTPS，因为它将自动选择默认端口443。

tomcat配置重定向

 
1，使用户HTTP访问自动重定向为HTTPS，直接在http.conf最后配置即可，在httpd.conf文件尾加入如下内容：
 
 
RewriteEngine on
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^/?(.*)$ https://%{SERVER_NAME}/$1 [L,R]
 
 
2，配置域名
 
 
<Engine defaultHost="localhost" name="Catalina"> 把defaultHost的值修改成你的域名 <Engine defaultHost="www.qiangzigz.pw" name="Catalina">
 
 
<Host name="www.qiangzigz.pw" appBase="webapps/qxw" 
unpackWARs="true" autoDeploy="true"> 
 
 
<Alias>qiangzigz.pw</Alias>  
 <Context path="" docBase="C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\qxw" debug="0" reloadable="true" ></Context>    

  </Host>  
 </Engine>          

 Alias标签配置后，就可以使用不带www的域名直接访问即可。

前言
使用步骤
1.创建error.html文件
2.编写web.xml
 

 
 
前言
 
提示：当我们访问tomcat的一个不存在的页面，返回错误信息如下：
 这样的界面直接暴露给用户并不友好，有时候还不安全，因此一般需要修改默认的错误页
 
 
使用步骤
 
1.创建error.html文件
 
webapps/ROOT目录下添加error.html代码如下（示例）：
 
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"><head>
<title>网页访问不了‹</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link rel="stylesheet" type="text/css" href="404/error_all.css?t=201303212934">
</head>
<body class="error-404">
<div id="doc_main">
    <section class="bd clearfix">
        <div class="module-error">
            <div class="error-main clearfix">
                <div class="label"></div>
                <div class="info">
                    <h3 class="title">啊哦，你所访问的页面不存在了，可能是炸了 ‹</h3>
                    <div class="reason">
                        <p>可能的原因：</p>
                        <p>1.防火墙端口未打开</p>
                        <p>2.维护升级中</p>
                    </div>
                </div>
            </div>
        </div>
    </section>
</div>
 
</body></html>
 
2.编写web.xml
 
\ROOT\WEB-INF\web.xml文件内容，指定错误状态码对应的界面,代码如下（示例）：
 
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                      http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
  version="4.0"
  metadata-complete="true">
