Mapping two identical classes in java with third party library

Question

I need to convert one object to other .The object has nested of many inner objects.But both source and destination objects are identical by data type , variable name , class name etc. Is there any effective tool to do so with less coding.

I have tried orika but its expecting to define like below

factory.registerClassMap(factory
                .classMap

with all the fields and inner object fields.I ended up with lots of iterator and setting filed mappings.

Help me or guide me Is there any other way to map objects with identical objects.

if i understand correctly your issue , you want to clone an object that has inner references , you could try Apache commons or check [here](http://stackoverflow.com/questions/9264066/beanutils-clonebean-deep-copy) the answers , otherwise youll have to implement a custom DeepCopy method — AntJavaDev, Jun 07 '16 at 06:47
No I dont want to clone the object .I have POJO and JAXB which are identical .I need to set the value from POJO to JAXB — Rithik_Star, Jun 07 '16 at 06:50
ok then you have the pojo object and you will clone it to the JAXB object , if they are identical as you saying and only the package name changes — AntJavaDev, Jun 07 '16 at 06:53

You could have a look at MapStruct.

Another alternative is Dozer. Classes can be mapped 1 on 1 by defining in the mapper xml file attribute wildcard="true". This means that it will automatically try to map every property in the two objects. When the attribute is set to false it will only map explicitly defined fields.

<?xml version="1.0" encoding="UTF-8"?>
<mappings xmlns="http://dozer.sourceforge.net"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://dozer.sourceforge.net
          http://dozer.sourceforge.net/schema/beanmapping.xsd">

    <mapping wildcard="true"> 
        <class-a>org.example.ObjectA</class-a>
        <class-b>org.example.ObjectB</class-b>   
    </mapping> 
</mappings>

is there any example to map two identical object using Mapstruct – Rithik_Star Jun 07 '16 at 06:52
Included other mapping framework in which 1 on 1 mapping is almost done out of the box. – uniknow Jun 07 '16 at 09:25
sorry , I m not using any xml file in my spring servlet 3 application – Rithik_Star Jun 07 '16 at 09:50
The file is dozer specific and has no relation to spring. It should be picked up from the classpath by the frameword itself. – uniknow Jun 07 '16 at 13:38
Answer can be generalized to use any available bean mapper: https://stackoverflow.com/questions/1432764/any-tool-for-java-object-to-object-mapping – tkruse Jan 15 '18 at 01:49

It's better to use a proper cloning library, check this one http://blog.jadira.co.uk/blog/2013/6/25/announcing-jadira-cloning.html
