MapMaid

MapMaid serializes, deserializes and validates Java objects in a clean and non-invasive way. It deeply understands and respects the concepts of Domain-Driven Design.

Rationale

Almost any modern application nowadays is dealing with mapping incoming requests to domain objects and outputting resulting domain objects to a specific format (typically JSON, XML or YAML).

As a result, we keep writing the same code over and over again:

• Parse strings into domain objects
• Validate the objects on initialization
• Process the requests
• Serialize the response objects

While there are numerous frameworks that help you on some of the stages of this process, we believe there is a need for a simple, non-invasive library that would allow you to integrate this process into your application seamlessly and concentrate on your business logic.

Highlighted features

• Designed for Domain-Driven Design:

  • MapMaid automatically understands factory methods
  • MapMaid understands the concept of Custom Primitives or Value Types
  • MapMaid understands the concept of Serialized Objects

• No Magic - MapMaid is using your objects the same way as a programmer:

  • MapMaid will not read nor write private fields
  • MapMaid will not write values into final fields
  • MapMaid will not invoke private methods
  • MapMaid will not generate dynamic proxies
  • MapMaid will not generate bytecode
  • MapMaid does not favour the use of annotations

• Domain-Driven Validation:

  • MapMaid allows you to check for validation exceptions and aggregates them accordingly
  • You will know precisely which field of which object was faulty
  • MapMaid also offers ways to detect redundant validation exceptions

• Non-intrusive usage and configuration:

  • Configuration in one place
  • No annotations
  • Simple adaptation to your specific style of defining objects
  • No dependencies to serialization and validation frameworks in your domain code

• Flexible:

  • Support for all common data formats (JSON, XML and YAML)
  • Serialize and deserialize any object of any class - no matter how weird their structure
