!!Add testGetPersons methods to DAO and Manager Tests [#3]

To create a List screen (also called a master screen), we need to create methods that will return all the rows from our ''person'' table. Let's start by adding tests for these methods to our PersonDaoTest and PersonManagerTest classes. I usually name this method ''getEntities'' (i.e. getPersons), but you could also use ''getAll'' or ''search'' - it's really just a matter of personal preference.

The reason I'm passing in a person object to the ''getPersons'' method is to allow for filtering (based on values in person) in the future.

Neither of these classes will compile at this point since the ''getPersons'' method does not exist on our Interfaces (PersonDao and PersonManager), not on our Implementations (PersonDaoHibernate and PersonManagerImpl). Let's giddyup and add those suckers.

Save all your files and make sure everything compiles with __ant clean compile__. Now you should be able to run both tests by running the following:

!!Add getPersons methods to DAO and Manager Interfaces and Implementation classes [#4]

First, let's modify our interfaces to include a ''getPersons'' method. Open src/dao/**/persistence/PersonDao.java and add the following:

;:''You will need to import java.util.List in each of these interfaces. In Eclipse, Ctrl+Shift+O is the fastest way.''

[{Java2HtmlPlugin

public List getPersons(Person person) throws DAOException;

}]

Then, open src/service/**/service/PersonManager.java and add a similar method:

[{Java2HtmlPlugin

public List getPersons(Object person) throws Exception;

}]

Now we need to add the implementation (a.k.a. "the meat") for these methods into our DAO and Manager implementations. Open src/dao/**/persistence/PersonDaoHibernate.java and add the following method:

;:%%(color: blue)''I looked in UserDAOHibernate.java and used the getUsers method as a template for getPersons.''

[{Java2HtmlPlugin

/**

* @see org.appfuse.persistence.PersonDao#getPersons(org.appfuse.model.Person)

public List getPersons(Person person) throws DAOException {

return getHibernateTemplate().find("from Person p order by upper(p.firstName)");

}

}]

You'll notice here that we're doing nothing with the ''person'' parameter. This is just a placeholder for now - in the future you may want to filter on it's properties using [Hibernate's Query Language|http://www.hibernate.org/hib_docs/reference/html/query-language.html] (HQL) or using [Criteria Queries|http://www.hibernate.org/hib_docs/reference/html/query-criteria.html].

Also, add a ''getPersons'' method to src/service/**/service/PersonManagerImpl.java:

[{Java2HtmlPlugin

/**

* @see org.appfuse.webapp.service.PersonManager#getPersons(java.lang.Object)

public List getPersons(Object obj) throws Exception {

return dao.getPersons((Person) person);

}

}]

Save all your files and make sure everything compiles with __ant clean package-web__. Now you should be able to run both tests by running the following:
