How to use jQuery to post JSON data to a Struts2 Action class

Question

I\'ve a problem sending data from jQuery to struts2 action class. I have seen the question: JSON Jquery to Struts2 action but I don\'t understand the solution quite well.

Answer 1

{"id":"1","code":"111","name":"ffffd"}

Step 1 : Create a bean/pojo to accumulate/encapsulate the above fields

class MyBean{
    String id,code,name;
    //getters & setters
}

Step 2 : Change your action code to receive a List of MyBeans

public class Update extends ActionSupport{
    private List data;

   //other code, getters & setters
}

Step 3: Configure your action to de-serialize JSON data and fill the action fields (using json-plugin)

    
        
         
            true
        

Step 4 : Make necessary changes in the ajax request body being sent to match the action-params/fields

var data = JSON.stringify(dataObj);
$.ajax({
  url: "Update",
  type: "post",
  data:  "data:"+data,
  dataType: 'json',
  contentType:"application/json;charset=utf-8",
  success : function(){
    alert("You made it!");
  }
});

The above code is untested.
