在POST请求中发送响应

Question

My route POST /article/create Application.create

Application.java file

public static void create(Article article) {
   article.save();
  //send article ID (article.id) after saving

}

Is it possible to send article.id as a response to the client once the article has been saved in the DB? If yes, what is the best way to do it

Answer 1

You didn't specify which version of play you are using, but if it's play2 your method signature looks like missing return type.

Please see more from here, and decide yourself how you want to return newly created id

http://www.playframework.com/documentation/2.2.x/JavaResponse

You have several possibilities to return id

• headers
• body of response
• or even cookies

Inside body you can return just id, or embed id inside json, xml, html or some other data structure.
