JAX-RS @CookieParam Annotation Example with RESTEasy 3
March 09, 2015
1. Primitive type
2. JAX-RS Cookie Class
3. A class with constructor with single string argument.
4. A class with static method named as valueOf with one string argument.
5. Using registered implementation of javax.ws.rs.ext.ParamConverterProvider
For more detail find the JAX-RS doc.
Here we will show demo for some scenarios discussed above. We are creating two classes as below.
UserDataOne.java
package com.concretepage;
public class UserDataOne {
private String sessionId;
public UserDataOne(String sessionId){
this.sessionId = sessionId;
}
public String getSessionId() {
return sessionId;
}
public void setSessionId(String sessionId) {
this.sessionId = sessionId;
}
}
UserDataTwo.java
package com.concretepage;
public class UserDataTwo {
private static String data;
public static String getSessionId() {
return data;
}
public static void valueOf(String sessionId){
data = sessionId;
}
}
EmployeeService.java
package com.concretepage;
import java.util.HashMap;
import java.util.Map;
import javax.ws.rs.CookieParam;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;
import org.jboss.resteasy.annotations.providers.jackson.Formatted;
@Path("/cookie")
public class EmployeeService {
@GET
@Path("/oneway")
@Produces("application/json")
@Formatted
public Response oneWay(@CookieParam("sessionid") String userAgent ) {
Map<String,String> map = new HashMap<String,String>();
map.put("sessionid", userAgent);
return Response.ok(map).build();
}
@GET
@Path("/secondway")
@Produces("application/json")
@Formatted
public Response secondWay(@CookieParam("sessionid") UserDataOne data) {
return Response.ok(data).build();
}
@GET
@Path("/thirdway")
public Response thirdWay(@CookieParam("sessionid") UserDataTwo data) {
return Response.ok(UserDataTwo.getSessionId()).build();
}
}
Output
If our application is setting cookie named as sessionid, then we can use below URL to test the application.1. http://localhost:8080/concretepage-1/employee/cookie/oneway
2. http://localhost:8080/concretepage-1/employee/cookie/secondway
3. http://localhost:8080/concretepage-1/employee/cookie/thirdway
