An example of mapping two classes is defined below. Note: Explicit xml mapping for 2 classes is not required if all the field mapping between src and dest object can be performed by matching on attribute name. Custom xml class mapping is only required when you need to specify any custom field mappings.

These mappings are bi-directional so you would never need to define an XML map for TestObjectPrime to TestObject. If these two classes had references to complex types that needed type transformation, you would also define them as mappings. Dozer recursively goes through an object and maps everything in it. Data type conversion is performed automatically. Dozer also supports no attribute mappings at all. If supplied two classes that are not mapped, it simply tries to map properties that are the same name.
