how to Auto Trim Strings of bean object in spring with Restful api?

Issue

I want to trim all the form string fields trim automatically (trailing & leading spaces only)

Suppose if I pass FirstName = " robert " Expected: "robert"

Controller class having following code :

@InitBinder
public void initBinder ( WebDataBinder binder )
{
    StringTrimmerEditor stringtrimmer = new StringTrimmerEditor(true);  
    binder.registerCustomEditor(String.class, stringtrimmer);
}

@RequestMapping(value = "/createuser", method = RequestMethod.POST)
public Boolean createUser(@RequestBody  UserAddUpdateParam userAddUpdateParam) throws Exception {

    return userFacade.createUser(userAddUpdateParam);
}  

when I debug the code, It's coming into @InitBinder but not trimming bean class string fields.

Solution

The annotation @InitBinder doesn't work with @RequestBody, you have to use it with the @ModelAttribute annotation

You can find more information in the Spring documentation:
