Spring MVC Controller mapping regex

Question

My controller mappings:

@RequestMapping(value = "{objectId}/{objectName: [a-zA-Z-]+}", method = GET)
public String getObjects(@PathVariable Integer objectId, Model model) { ... }

@RequestMapping(value = "{objectId}/{objectName: [a-zA-Z-]+}_{category}", method = GET)
public String getObjectsForCategories(@PathVariable Integer objectId, 
                                      @PathVariable String category, 
                                      Model model) { ... }

And the urls I'm hitting:

http://localhost:8080/objects/2/xyz

http://localhost:8080/objects/2/xyz_mobile

Spring unable to find the handler and complains with No mapping found for HTTP request.

Remove the space between : and regex and Try again.

According to the Spring MVC documentation:

The @RequestMapping annotation supports the use of regular expressions in URI template variables. The syntax is {varName:regex} where the first part defines the variable name and the second - the regular expression.

So, you should remove the space between : and regex, like the following:

@RequestMapping(value = "{objectId}/{objectName:[a-zA-Z-]+}", method = GET)
                                                ^ Space is removed
