This is probably closely related to <a href="https://jira.springsource.org/browse/SPR-6164" rel="noreferrer">SPR-6164</a>. Briefly, the framework tries to apply some smarts to the URI interpretation, removing what it thinks are file extensions. This would have the effect of turning <code>blah2010.08.19-02:25:47</code> into <code>blah2010.08</code>, since it thinks the <code>.19-02:25:47</code> is a file extension.

As described in the linked issue, you can disable this behaviour by declaring your own <code>DefaultAnnotationHandlerMapping</code> bean in the app context, and setting its <code>useDefaultSuffixPattern</code> property to <code>false</code>. This will override the default behaviour, and stop it molesting your data.

Everything after the last dot is interpreted as file extension and cut off by default. 
In your spring config xml you can add <code>DefaultAnnotationHandlerMapping</code> and set <code>useDefaultSuffixPattern</code> to <code>false</code> (default is <code>true</code>).

So open your spring xml <code>mvc-config.xml</code> (or however it is called) and add

<pre><code>&lt;bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"&gt;
 &lt;property name="useDefaultSuffixPattern" value="false" /&gt;
&lt;/bean&gt;
</code></pre>

Now your <code>@PathVariable</code> <code>blahName</code> (and all other, too) should contain the full name including all dots.

I just ran into this and the solutions here didn't generally work as I expected.

I suggest using a SpEL expression and multiple mappings, e.g.

<pre><code>@RequestMapping(method = RequestMethod.GET, 
 value = {Routes.BLAH_GET + "/{blahName:.+}", 
 Routes.BLAH_GET + "/{blahName}/"})

The file extension problem only exists if the parameter is in the last part of the URL. Change 

<pre><code>@RequestMapping(method = RequestMethod.GET, value = Routes.BLAH_GET + "/{blahName}")

to 

<pre><code>@RequestMapping(

If you can edit the address that requests are sent to, simple fix would be to add a trailing slash to them (and also in the <code>@RequestMapping</code> value):

<pre><code>/path/{variable}/
</code></pre>

so the mapping would look like:

<pre><code>RequestMapping(method = RequestMethod.GET, value = Routes.BLAH_GET + "/{blahName}/")
</code></pre>

My preferable solution to prevent the Spring MVC @PathVariable to get truncated is to add trailing slash at the end of the path variable.

For example:

<pre><code>@RequestMapping(value ="/email/{email}/")
</code></pre>

So, the request will look like:

<pre><code>http://localhost:8080/api/email/test@test.com/
</code></pre>

I have a controller that provides RESTful access to information:

<pre><code>@RequestMapping(method = RequestMethod.GET, value = Routes.BLAH_GET + "/{blahName}")
public ModelAndView getBlah(@PathVariable String blahName, HttpServletRequest request,
 HttpServletResponse response) {
</code></pre>

The problem I am experiencing is that if I hit the server with a path variable with special characters it gets truncated. For example:
<a href="http://localhost:8080/blah-server/blah/get/blah2010.08.19-02:25:47" rel="noreferrer">http://localhost:8080/blah-server/blah/get/blah2010.08.19-02:25:47</a>

The parameter blahName will be blah2010.08

However, the call to request.getRequestURI() contains all the information passed in.

Any idea how to prevent Spring from truncating the @PathVariable?
