Develop the Data Transfer Object

We will divide the user interface development into the following three tasks:

• The data transfer object
• The mock service
• The mock user interface

We will look at each of these tasks one by one.

Data transfer object

The data transfer object contains ProtocolDto which has an identifier and a name. There are two subtypes of ProtocolDto known as TCPDto and SNMPDto. The @JsonTypeInfo annotation is used to denote Polymorphic types i.e., the ability of an object to take on many forms and, the kind of metadata used for serializing and deserializing type information. The @JsonSubTypes annotation is used to denote sub-types of serializable polymorphic types.
