Answer 1

You can manage it in server side with a tricky way.
public class User {
private int id;
private String name;
#JsonIgnore // ignore this field when serialize
private String number;
#JsonProperty(value = "number") // change name of field when serialize
private int intValueOfNumber;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
public int getIntValueOfNumber() {
return Integer.parseInt(number); // parse number string to int
}
public void setIntValueOfNumber(int intValueOfNumber) {
this.intValueOfNumber = intValueOfNumber;
}
}
In this entity #JsonIgnore annotation is ignore your field for JSON serialization and pass intValueOfNumber as int to JSON. Your json will be following:
{"id":1,"name":"Java","number":44124}
You may lost zero suffix of number string when you parse it to int.
