JAX RS – 12 – @FormParam & @Form
Merhaba Arkadaslar
Bu bolumde @FormParam ve @Form annotation’larini inceleyecegiz.
PersonResource.java
package _06.formParam.service;
import javax.ws.rs.FormParam;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
@Path("/person-formParam")
public class PersonResource {
@POST
@Path("/addPerson")
public String addPerson(@FormParam("name") String name, @FormParam("surname") String surname) {
String message = "addPerson is called. " + "Welcome , " + name + " " + surname;
return message;
}
}
Dikkat edecek olursak @POST annotation’ini kullandik. @FormParam annotation ile formdaki ilgili form parametrelerine erisim saglayabiliriz.
The @javax.ws.rs.FormParam annotation is used to access application/x-www-form- urlencoded request bodies.
When the input request body is of the type "application/x-www-form-urlencoded", a.k.a. an HTML Form, you can inject individual form parameters from the request body into method parameter values.
Ornegimizi test etmek icin Desktop’ta basit bir HTML form olusturabiliriz ;

Benzer sekilde action kismini resteasy projesine gonderecek sekilde degistirip test edebiliriz.
<form id="form1" action="http://localhost:8080/injavawetrust.resteasy.tutorial/person-formParam/addPerson" method="post">
Ya da onceki bolumlerde ekledigimiz REST plugin’leri araciligiyla HTTP POST istegini data form bilgilerini ekleyerek gonderebiliriz.
Bir baska ornek olarak @Form annotation’ini kullanabiliriz. Bu annotation sadece RESTEasy icin gecerlidir.
Person.java
package _06.formParam.model;
import javax.ws.rs.FormParam;
public class Person {
@FormParam("name")
private String name;
@FormParam("surname")
private String surname;
//getters and setters
//toString
}
@Form annotation’ini import org.jboss.resteasy.annotations.Form olarak import ediyoruz.
PersonResource.java
package _06.formParam.service;
import javax.ws.rs.FormParam;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import org.jboss.resteasy.annotations.Form;
import _06.formParam.model.Person;
@Path("/person-formParam")
public class PersonResource {
@POST
@Path("/addPerson")
public String addPerson(@FormParam("name") String name, @FormParam("surname") String surname) {
String message = "addPerson is called. " + "Welcome , " + name + " " + surname;
return message;
}
@POST
@Path("/addPersonModel")
public String addPersonModel(@Form Person person) {
String message = "addPersonModel is called.";
return message + " " + person.toString();
}
}
