Spring MVC bean mapping to HTTP GET request parame

问题:

In Jersey there is @BeanParam annotation with which I can have request parameters mapped to bean attributes.

In Spring I can find only @RequestBody which obviously works with request body and not request parameters.

Is there a way to have request parameters mapped to a bean using Spring?

回答1:

Simply create a Pojo Java Bean with fields with names that match your request parameters.

Then use this class as an argument for your request handler method (without any additional annotations)

public class Example {
   private String x;
   private Integer y;

   //Constructor without parameter needed!
   public Example(){}

   //Getter + Setter
}

@Controller
@RequestMapping("someUrl")
public class SomeController {

    @RequestMapping
    public String someHandler (Example example) {
          System.out.println(example.getX());
          return "redirect:someOtherUrl";
    }
}
