How the home page jumps to the login page in the Nutz_web app

First, preface

When Web application development, the address bar input ip+port+appname, usually can jump to the login page. Here are the three ways I know and verify the jump.

Ii. preparatory work

The processing required to use two URLs is as follows:

    @At ("/index")    @Ok ("Redirect:/tologin")    @Filters// indicates that the URL is not filtered (using an empty filter) public    void  init () {            }        @At ("/tologin")    @Ok ("") // Configure the address path of the login page here     @Filters    publicvoid  Tologin () {            }

Three or three ways to jump to the login page

1. Configuration <welcome-file-list> index.jsp page path for presence

<welcome-file-list> is configured as follows:

    <welcome-file-list>       <welcome-file>index.jsp</welcome-file>    </welcome-file-list >

Here index.jsp in the WebContent directory. and add the following code to the index.jsp:

<%    request.sendredirect ("/index")%>

2, configuration <welcome-file-list> for a URL. As shown below:

    <welcome-file-list>       <welcome-file>index.html</welcome-file>    </welcome-file-list >

Here: index.html is a URL path. At this point, you need to add an empty index.html file under the WebContent directory. This way, when you enter Ip+port+appname, the/index.html path is accessed by default. This allows you to jump to the login page.

Note : If you use struts2, the ur name may be index.action. In this case, you need to add: index.action empty file in the WebContent directory. The file name is consistent with the configured URL.

3, the use of uriwriter implementation does not configure <welcome-file-list> and do not add files such as index.jsp or index.html, jump to the login page function. "It's not recommended because it complicates simple problems." 】

Step 1: Introduce the Urlwriter jar package

Step 2: Add the following configuration in Web. xml:

  <filter>    <filter-name>UrlRewriteFilter</filter-name>    <filter-class> org.tuckey.web.filters.urlrewrite.urlrewritefilter</filter-class>  </filter>  < filter-mapping>    <filter-name>UrlRewriteFilter</filter-name>    <url-pattern>/*  </url-pattern>  </filter-mapping>

Step 3: Add a file named: Urlrewrite.xml under Web-inf (Note: The filename can only be urlrewrite.xml), the contents are as follows:

<?xml version= "1.0" encoding= "Utf-8"? ><! DOCTYPE urlrewrite Public "-//tuckey.org//dtd urlrewrite 3.2//en"        "Http://tuckey.org/res/dtds/urlrewrite3.2.dtd "><urlrewrite>    <rule>        <from>^/$</from>        <to>/index</to>    </rule>  </urlrewrite>

That is, when the path is "/", it will be converted to execute "/index" by default in the form of forward. In order to achieve the/index access to the login page to achieve the jump.
