Jackson - custom serializer that overrides only specific fields

Question

I know how to use a custom serializer in Jackson (by extending JsonSerializer), but I want the default serializer to work for all fields, except for just 1 fiel

Answer 1

with the help of @JsonView we can decide fields of model classes to serialize which satisfy the minimal criteria ( we have to define the criteria) like we can have one core class with 10 properties but only 5 properties can be serialize which are needful for client only

Define our Views by simply creating following class:

public class Views
{
    static class Android{};
    static class IOS{};
    static class Web{};
}

Annotated model class with views:

public class Demo 
{
    public Demo() 
    {
    }

@JsonView(Views.IOS.class)
private String iosField;

@JsonView(Views.Android.class)
private String androidField;

@JsonView(Views.Web.class)
private String webField;

 // getters/setters
...
..
}

Now we have to write custom json converter by simply extending HttpMessageConverter class from spring as:

    public class CustomJacksonConverter implements HttpMessageConverter
