Rewrite URL in Spring Framework

This post is about Spring Framework; if you are not familiar with this framework, reading this article may be useful to you.Using slug in URLs has many benefits, including SEO-friendly and user-friendly. Tuckey is a Java Web Filter which allows you to rewrite URLs before they get to your code ( like Apache’s mod_rewrite).

for using tuckey in spring framework, you must add it’s dependency to pom.xml:

<dependency>  
    <groupId>org.tuckey</groupId>  
    <artifactId>urlrewritefilter</artifactId>  
    <version>4.0.3</version>  
</dependency>

Then in web.xml must add this filter:

<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>/portal/*</url-pattern>  
    <dispatcher>REQUEST</dispatcher>  
    <dispatcher>FORWARD</dispatcher>  
</filter-mapping>

finally, you should create a urlrewrite.xml file in procjetName/src/main/webapp/WEB-INF path and write your rules for rewrite URLs into this file. for example:

<?xml version="1.0" encoding="utf-8"?>  
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 4.0//EN" "http://www.tuckey.org/res/dtds/urlrewrite4.0.dtd">  
<urlrewrite>  
  <rule>  
     <from>^/news/(.*)/(.*)$</from>  
     <to type="passthrough">/rest/news/details/$1?title=$2</to>  
   </rule>  
</urlrewrite>

There are many other things you can do with the tuckey, including: slugify URLs, showing specific error page for HTTP error responses, URL redirection and so on.
