BeanCopy the annotated bean mapper

BeanCopy ia a bean mapper that works annotation based.

To copy fields of the source and target that are different just use @Copy.
To copy fields of the source and target that are the same dont annotate them.
To prevent copying a field just use the @IgnoreCopy annotation.

Example code:

Fields with different name:

@Copy(copyTo = "testString2")
private String testString;

Fields with the same name:

private String testString;

Fields that should not be copied:

@IgnoreCopy
private String testString;

How to copy from one bean to the other:
In this case the testBean has the value and the emptyTestBean is the one where it is copied to.

TestBean testBean = new TestBean();
EmptyTestBean emptyTestBean = new EmptyTestBean();
BeanCopier beanBeanCopier = new BeanCopier();
beanBeanCopier.beanCopy(testBean,emptyTestBean);

One of the advantages of using BeanCopy is that there is no need for setter methods. This means that you can copy from model to view and vica versa.
