Spring-mvc – set a default value for a path variable at RequestMapping in SpringMVC

spring-mvc

Is it possibile to set a default value to a @PathVariable in SpringMVC?

 @RequestMapping(value = {"/core/organization/{pageNumber}", "/core/organization"} , method = RequestMethod.GET)
    public String list(@PathVariable Integer pageNumber, ModelMap modelMap) {

In this case. If I access the page without pageNumber I want to set a default value to 1.

Is that possible?

There's no way to to set a default value, but you can create two methods:

@RequestMapping(value = {"/core/organization/{pageNumber}", "/core/organization"} , method = RequestMethod.GET)
    public String list(@PathVariable Integer pageNumber, ModelMap modelMap){
...
}


@RequestMapping(value = {"/core/organization/", "/core/organization"} , method = RequestMethod.GET)
    public String list(@PathVariable Integer pageNumber, ModelMap modelMap){
Integer pageNumber=defaultvalue;
...
}

Non-matched part of the URL is exposed as a request attribute named HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE:

@RequestMapping("/{id}/**")
public void foo(@PathVariable("id") int id, HttpServletRequest request) {
    String restOfTheUrl = (String) request.getAttribute(
        HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
    ...
}

GET http://localhost:8080/public/test/1,2,3,4

@RequestMapping(value="/test/{firstNameIds}", method=RequestMethod.GET)
@ResponseBody
public String test(@PathVariable String[] firstNameIds)
{
    // firstNameIds: [1,2,3,4]
    return "Dummy"; 
}

(tested with Spring MVC 4.0.1)
