[FIXED] How to set alias for request parameters in Spring-mvc?

Issue

When having a bean object for request params in spring: is there a way to define an alias for a bean properties?

@RestController
public class MyServlet {
   @GetMapping
   public void test(MyReq req) {
   }
}

public class MyReq {
   @RequestParam("different-name") //this is invalid
   private String name;
   private int age;
}

Of course @RequestParam does not work, but is there a similar annotation I could use?

Solution

Request parameter are bind by setters. You can add an extra setter with original parameter name. Something like:

public class MyReq {
   private String name;
   private int age;

   public void setDifferentName(String differentName) {
      this.name=differentName;
   }
}

NOTE: it will work only if your parameter is camel case like differentName=abc. Will not work with different-name=abc.
