I have a model like this:
public class Employee {
@JsonProperty("emplyee_id")
private Integer id;
@JsonProperty("emplyee_first_name")
private String firstName;
@JsonProperty("emplyee_last_name")
private String lastName;
@JsonProperty("emplyee_address")
private String address;
@JsonProperty("emplyee_age")
private Byte age;
@JsonProperty("emplyee_level")
private Byte level;
//getters and setters
}
now I need to create two JSONs using this (only) model.
the first one must like this for example:
{
"employee_id":101,
"employee_first_name":"Alex",
"employee_last_name":"Light",
"employee_age":null,
"employee_address":null
}
and the second one must like this for example:
{
"employee_id":101,
"employee_level":5
}
by the way, I already tested @JsonIgnore and @JsonInclude(JsonInclude.Include.NON_NULL).
the problem of the first one (as much as I know) is, those fields can't be included in other JSONs (for example if level get this annotation, it won't be included in the second JSON)
and the problem of the second one is, null values can't be included in JSON.
so can I keep null values and prevent some other property to be included in JSON without creating extra models? if the answer is yes, so how can I do it? if it's not I really appreciate if anyone gives me the best solution for this state.
thanks very much.
it could be useful for you using @JsonView annotation
public class Views {
public static class Public {
}
public static class Base {
}
}
public class Employee {
@JsonProperty("emplyee_id")
@JsonView({View.Public.class,View.Base.class})
private Integer id;
@JsonProperty("emplyee_first_name")
@JsonView(View.Public.class)
private String firstName;
@JsonProperty("emplyee_last_name")
@JsonView(View.Public.class)
private String lastName;
@JsonProperty("emplyee_address")
private String address;
@JsonProperty("emplyee_age")
private Byte age;
@JsonProperty("emplyee_level")
@JsonView(View.Base.class)
private Byte level;
//getters and setters
}
in your json response add @JsonView(Public/Base.class) it will return based on jsonview annotations
//requestmapping
@JsonView(View.Public.class)
public ResponseEntity<Employee> getEmployeeWithPublicView(){
//do something
}
response:
{
"employee_id":101,
"employee_first_name":"Alex",
"employee_last_name":"Light",
"employee_age":null,
"employee_address":null
}
for the second one
//requestmapping
@JsonView(View.Base.class)
public ResponseEntity<Employee> getEmployeeWithBaseView(){
//do something
}
response
{
"employee_id":101,
"employee_level":5
}
