How to copy properties from a bean to another bean in different class? [duplicate]

Question

I have two java class with same properties names.How Can I copy all the properties to another bean filled with data.I don't want to use the traditional form to copy properties because I have a lot of properties.

Thanks in advance.

1 class

@ManagedBean @SessionScoped public class UserManagedBean implements Serializable {      private static final long serialVersionUID = 1L;     private String userSessionId;     private String userId;     private String name;     private String adress;     ...................... 

2 class

public class UserBean {      private String userSessionId;     private String userId;     private String name;    .................... 

Answer 1

Use BeanUtils:

import org.apache.commons.beanutils.BeanUtils;  UserBean newObject = new UserBean();  BeanUtils.copyProperties(newObject, oldObject); 

Answer 2

Check out the Dozer Framework - its an object to object mapping framework. The idea is that:

• Usually it will map by convention.
• You can override this convention with a mapping file.

. . therefore mapping files are as compact as possible. Its useful for many cases, such as mapping a use-case specify service payload on to the reusable core model objects.

When delivering the SpringSource training courses we used to point out this framework very often.

Edit:

These days try MapStruct.
