Spring MVC is dropping a @PathVariable

Question

If I hit the controller multiple times and hammer it, occasionally my modelCode parameter comes through as null. However the URL has the modelCode in it. Using Spring Framework 3.0.5.RELEASE

 @RequestMapping(value="ws/getallvariants/{channelCode}/{modelCode}/{regionId}/{year}")
    public ModelAndView getAllVariants(@PathVariable("channelCode") String channelCode, 
          @PathVariable("modelCode") String modelCode,@PathVariable("regionId") String regionId,@PathVariable("year") String year){ 

    if (modelCode == null)
    {
        int i = 0; // this should never hit, but does.
    }

Have you checked the scope for that controller (is it the default singleton)? — nickdos, Apr 15 '11 at 23:11

Yes, RegEx was the most reliable for me as well. Did this to grab an email address as a parameter:

@RequestMapping(value = "rest/userreadserv/search/{email:.+}", method = RequestMethod.GET)
public ResponseEntity getUserAccountByEmail(@PathVariable String email) {...}

Take a look at Spring MVC @PathVariable getting truncated . The regex approach worked for me:

@RequestMapping({ "/servers/{serverName:.+}" })

In this case not the issue. The parameter is 2 or three alpha numeric characters, no decimals. I've also seen the regionId now go null. – Dilbert789 Apr 13 '11 at 16:38

//in your xml dispatcher  add this property to your default annotation mapper bean as follow
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
    <property name="alwaysUseFullPath" value="true"></property>
</bean>

Updating the spring framework again to the latest version appears to have worked. Apparently when we updated our framework something didn't work correctly.

EDIT:

So this wasn't our issue at all... We had implemented a String Trimmer Editor incorrectly and it was keeping state. So when we put the call under load it would cross results.

And a year later the issue re-appears. It appears that it wasn't solved in the first place. – Dilbert789 Sep 19 '12 at 17:51
The issue was a stringTrimmerEditor actually that wasn't implemented correctly. – Dilbert789 Sep 20 '12 at 14:50
