java-ee Java RESTful Web Services (JAX-RS) POST Method
Example
import javax.ws.rs.FormParam;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;
@Path("hello")
public class HelloWorldResource {
@POST
@Path("/receiveParams")
public Response receiveHello(@FormParam("name") String name, @FormParam("message") String message) {
//process parameters
return Response.status(200).build();
}
@POST
@Path("/saveObject")
@Consumes("application/json")
public Response saveMessage(Message message) {
//process message json
return Response.status(200).entity("OK").build();
}
}
First method can be invoked through HTML form submission by sending captured input parameters. Form submit action should point to -
/hello/receiveParams
Second method requires Message POJO with getters/setters. Any REST client can call this method with JSON input as -
{"sender":"someone","message":"Hello SO!"}
POJO should have the same property as JSON to make serialization work.
public class Message {
String sender;
String message;
public String getSender() {
return sender;
}
public void setSender(String sender) {
this.sender = sender;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
