About this tutorial

This is a tutorial to show how to create and manage Hibernate relationships within AppFuse. This tutorial was written for AppFuse 1.8 and the AppGen pieces may not work with previous versions.

[1] Create Weblog.java, Entry.java and add XDoclet tags
[2] [Many-to-One] Create a new Category object and modify Entry.java to use it
[3] [One-to-Many] A Weblog object can have many Entries
[4] [Many-to-Many] ???
[5] Lazy-Loading Issues
[6] Managing relationships and indexed properties in the UI

Create Weblog.java, Entry.java and add XDoclet tags [#1]

For our purposes, the Weblog entity is a list of available weblogs. A Weblog object has the following properties an id, a username, a dateCreated, and a blogTitle. Every Entry object has an id, a text, and a timeCreated property. The first thing to do is create some objects to persist. Let's create both a "Weblog" object and an Entry object (in the src/dao/**/model directory).




package org.appfuse.model;



public class Weblog extends BaseObject {

  private Long id;

  private String username;

  private Date dateCreated;

  private Date blogTitle;





    /*

     Generate your getters and setters using your favorite IDE: 

     In Eclipse:

     Right-click -> Source -> Generate Getters and Setters

    */

}




package org.appfuse.model;



import java.util.Date;



import org.apache.commons.lang.builder.EqualsBuilder;

import org.apache.commons.lang.builder.HashCodeBuilder;

import org.apache.commons.lang.builder.ToStringBuilder;

import org.apache.commons.lang.builder.ToStringStyle;



/**

 * @hibernate.class table="entry"

 */

public class Entry extends BaseObject {



  private Long id;



  private String text;



  private Date timeCreated;



  private Integer version;

[Many-to-One] Create a new Category object and modify Entry.java to use it [#2]

[One-to-Many] A Weblog object can have many Entries [#3]

[Many-to-Many] ??? [#4]
