In JAX-RS, you can use @FormParam annotation to bind HTML form parameters value to a Java method. The following example show you how to do it :
1. HTML Form
See a simple HTML form with “post” method.
<html> <body> <h1>JAX-RS @FormQuery Testing</h1> <form action="rest/user/add" method="post"> <p> Name : <input type="text" name="name" /> </p> <p> Age : <input type="text" name="age" /> </p> <input type="submit" value="Add User" /> </form> </body> </html>
2. @FormParam Example
Example to use @FormParam to get above HTML form parameter values.
import javax.ws.rs.FormParam;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;
@Path("/user")
public class UserService {
@POST
@Path("/add")
public Response addUser(
@FormParam("name") String name,
@FormParam("age") int age) {
return Response.status(200)
.entity("addUser is called, name : " + name + ", age : " + age)
.build();
}
}
3. Demo
Access HTML Page. URL : http://localhost:8080/RESTfulExample/UserForm.html
When “add user” button is clicked, it will redirect to URL : http://localhost:8080/RESTfulExample/rest/user/add
and display the following output :
addUser is called, name : favtuts, age : 30Download Source Code
