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" and Entry objects (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;



public class Entry extends BaseObject {

  private Long id;

  private String text;

  private Date timeCreated;





    /*

     Generate your getters and setters using your favorite IDE: 

     In Eclipse:

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

    */

}

[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]
