Jersey @BeanParam webservices Restful JAX-RS tutorial
The annotation that may be used to inject custom JAX-RS "parameter aggregator" value object into a resource class field, property or resource method parameter.
The JAX-RS runtime will instantiate the object and inject all it's fields and properties annotated with either one of the @XxxParam annotation (@PathParam, @FormParam ...) or the @Context annotation. For the POJO classes same instantiation and injection rules apply as in case of instantiation and injection of request-scoped root resource classes.
Example
package com.candidjava.webservices.controller;
import javax.ws.rs.BeanParam;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import com.candidjava.webservices.bean.User;
@Path("/User")
public class RegisterProcess
{
@POST
@Path("/RegisterProcess")
@Produces(MediaType.APPLICATION_JSON)
public Response getRegisterDetails(@BeanParam User user)
{
String username = user.getUsername();
String password = user.getPassword();
System.out.println(username);
System.out.println(password);
return Response.ok().status(200).entity(user).build();
}
}User Bean
package com.candidjava.webservices.bean;
import javax.validation.constraints.Min;
import javax.validation.constraints.NotNull;
import javax.ws.rs.FormParam;
public class User
{
@NotNull
@Min(value=3)
@FormParam("txt_username")
private String username;
@FormParam("txt_password")
private String password;
public String getUsername()
{
return username;
}
public void setUsername(String username)
{
this.username = username;
}
public String getPassword()
{
return password;
}
public void setPassword(String password)
{
this.password = password;
}
}
