any tool for java object to object mapping? [closed]

Answer 1

I suggest you try JMapper Framework.

It is a Java bean to Java bean mapper, allows you to perform the passage of data dynamically with annotations and / or XML.

With JMapper you can:

• Create and enrich target objects
• Apply a specific logic to the mapping
• Automatically manage the XML file
• Implement the 1 to N and N to 1 relationships
• Implement explicit conversions
• Apply inherited configurations

Answer 2

You could try Dozer.

Dozer is a Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types.

Dozer supports simple property mapping, complex type mapping, bi-directional mapping, implicit-explicit mapping, as well as recursive mapping. This includes mapping collection attributes that also need mapping at the element level.

Answer 3

ModelMapper is another library worth checking out. ModelMapper's design is different from other libraries in that it:

• Automatically maps object models by intelligently matching source and destination properties
• Provides a refactoring safe mapping API that uses actual code to map fields and methods rather than using strings
• Utilizes convention based configuration for simple handling of custom scenarios

Check out the ModelMapper site for more info:

Answer 4

You can also try mapping framework based on Dozer, but with Excel mapping declaration. They've got some tools and additional cool features. Check at http://openl-tablets.sf.net/mapper

Answer 5

I'm happy to add Moo as an option, although clearly I'm biased towards it: http://geoffreywiseman.github.com/Moo/

It's very easy to use for simple cases, reasonable capable for more complex cases, although there are still some areas where I can imagine enhancing it for even further complexities.

Answer 6

Use Apache commons beanutils:

static void copyProperties(Object dest, Object orig) -Copy property values from the origin bean to the destination bean for all cases where the property names are the same.
