Example on how to integrate Orika mapper into Spring in a very clean way.

OrikaBeanMapper (class)

This is the class you want to import into your project, or just copy-paste as it is, since, it works the same if you have zero or many custom mappers or converters.

It does two things:

• Configures the Orika MapperFactory and factory builder.
• Registers into the MapperFactory all CustomConverter and CustomMapper classes annotated with @Component.

To use it we just need to autowire it into the class and we'll be able to map any combination of classes with it:

@Autowired
private OrikaBeanMapper mapper;
private User user;

user = new User("Leo", "Messi", 28);
UserDto dto = mapper.map(user, UserDto.class);

Custom Mappers (example)

• Create a class that extends CustomMapper whenever you need to customize the mapping between two classes.
• Override mapAtoB and/or mapBtoA methods and implement the logic on how to map the attributes that need a specific way of being mapped. The fields not specified here will be mapped by default, i.e. matching by name and copying the value from one bean to the other.
• Annotate the class with @Component so it can be discovered by OrikaBeanMapper.

Custom Converters (example)

• Create a class that extends CustomConverter whenever you need to tell Orika how to convert a class type to another when a mapping is being done.
• Implement convert method.
• Annotate the class with @Component so it can be discovered by OrikaBeanMapper.
