如何将JsonView应用于嵌套实体

public class Views {
    public static class Public {}
    public static class Internal extends Public {}
}

public class User {
    @JsonView(Views.Public.class)
    private String username;

    @JsonView(Views.Internal.class)
    private String password;

    // getters and setters
}

ObjectMapper mapper = new ObjectMapper();

// 序列化时指定视图
String publicViewJson = mapper.writerWithView(Views.Public.class).writeValueAsString(user);
String internalViewJson = mapper.writerWithView(Views.Internal.class).writeValueAsString(user);

// 反序列化时指定视图
User publicViewUser = mapper.readerWithView(Views.Public.class).forType(User.class).readValue(publicViewJson);
User internalViewUser = mapper.readerWithView(Views.Internal.class).forType(User.class).readValue(internalViewJson);
