使用Spring MVC处理多个URL参数

Question

I have a Spring Controller class set up with @RequestMapping("/vehicle") set at the class level. One method of this class is

@RequestMapping(method = RequestMethod.GET)
@ResponseBody
public Vehicle getVehicleByRegistration(
    @RequestParam(value="doAs", required = true) String doAsUser,
    @RequestParam(value="registration", required = true) String registration) throws IOException {

    return vehicleController.getByIndex(registration, doAsUser);
}

and I'm sending queries to it like:

curl -iv localhost:8096/vehicle/?doAs=user&registration=ABC1234

When executed, I get a response containing:

"exception":"org.springframework.web.bind.MissingServletRequestParameterException","message":"Required String parameter 'registration' is not present"

If I reverse the order of doAs and registration in the URL then the error says that 'doAs' is not present .

If I modify the method to only take one argument (either doAs or registration ) then it works fine.

What's going wrong here? I've tried using param in the @RequestMapping but that doesn't work either.

Answer 1

You're not protecting the ampersand from the shell, which is why you're also getting other weird shell output. Put the URL in quotes.

Answer 2

Try quoting the url you are passing to curl, in other post I saw that the ampersant was backgrounding the job. try:

curl -iv "localhost:8096/vehicle/?doAs=user&registration=ABC1234"
