I have the following request

{
"attachments":[
    {
        "fields":[
            {
                "value":"Testing value"
            }
        ]
    }
],
"channel":"testing",
"value":"Testing value"

}

and want to make it as a request in Java, but I am struggling how to represent it and use it. So far I've done this

public class RequestTest {
    ArrayList<ArrayList<String>> attachments = new ArrayList<ArrayList<String>>();
    ArrayList<String> fields = new ArrayList<String>();
    private String channel;
    private String value;
}

But I am not sure how to put the value and how to call it after that.

CodePudding user response：

You have to create an object structure like:

public class RequestTest {
    ArrayList<Attachment> attachments = new ArrayList<>();
    private String channel;
    private String value;
}

public class Attachement {
    ArrayList<Field> fields = new ArrayList<>();
}

public class Field {
  String value;
}     

Then you can use jackson or gson to create the json string you expect.

CodePudding user response：

If you want to present the request in Java class, then you should create a class named "Field" and class named "Attachment".

    public class Field{
        private String value;
    }

    public class Attachment{
        private List<Field> fields;
    }

    public class RequestTest{
        private List<Attachment> attachments;
        private String channel;
        private String value;
    }

If you want to present it with JsonObject, you can refer to JsonObject
