Gourmet Recipe Manager - Spring Boot - Version 2

This is a port of Thomas Hinkle (thinkle) Gourmet Recipe Manager.

As explained in the original version, thinkle's original Gourmet Recipe Manager desktop app has suffered frequently over the years by changes made to external components that it depended on and unfortunately he has not had the time to repair the the app after recent upgrades (including Python 3 and Gnome library) changes broke it.

Java is not only "write once/run anywhere", but also was designed for an environment where changes should not break existing Java apps. Hence the port. It was easier than trying to learn all the new external resources used by the Python version, make detailed repairs and wait for it to break again.

Functionality

This version of the system should provide all of the basic Recipe management functions, including adding new recipes, pasting in lists of ingredients, and managing shopping categories. The ultimate intent is to provide all functions that the original Python app did.

Building the app

You must have Maven installed on your system to build a copy of the app from scratch. You must have Java 11 or later installed on your system to run Maven and to run the app.

This project can be built on the command line using the mvn clean install command if you have Maven installed in your PATH.

Note that the first time you run Maven, it may download a lot of data from the Internet. This data will be cached by Maven so thereafter, you will not need an Internet connection unless there are changes to the app.

Running the app

This project can be run from the command line by using the mvn spring-boot:run command. Or do an install build and use the JAR file that Maven builds in the target directory. for example:

java -jar target/gourmetj-0.1.1-SNAPSHOT.jar

The actual JAR name will vary depending on the build version. You can copy this jar to any location you prefer.

You must have a recipe database file (see below) to store the recipes in. By default, it will be looked for in your home directory.

As of the 0.1.4 release, the parts of the application that can alter the database are now password-protected. You will need a .gourmetpw file to contain your userid/password definitions. By default it should be in the same directory that you are running the application from. A sample password file is included in this project.

To actually access the application, open your web browser to http://localhost:8080

Database

This product uses the same database as the Python-based version of the system, which is a SQLite3 database named recipes.db.

At the moment this app cannot build a database from scratch, so you must use an existing copy of a recipes.db file.

Note on JavaServer Faces

The Spring Boot version supersedes a previous port based on the Apache Tobago JSF tag library. It uses the PrimeFaces JSF tag library, as presently that platform has better Spring Boot support. Plus Tobago is quite different from most of the extension tag libraries to the point where it almost isn't JSF.

New in Version 2.0

Database change

The backing database as defined in the project is now MySQL instead of SQLite. The SQLite JDBC driver may have been a bit casual about a few things compared to MySQL. The JPA should work for either database now, although it should be noted that SQLite isn't really intended for multi-user webapps and should only be employed when you run this app on your local desktop.

Improved graphics support

A lot of recipe websites publish images in webp form. Support for webp has now been added.

Better session management

JSF tends to depend on session-scope context. Sessions, however time out and this has been an annoyance when a recipe is being displayed. To minimize this, better timeout mechanisms have been installed and the recipe browser keeps last-search and search-type values in long-lived cookies on the client. The server will read and cache them, but if the server times out, it will automatically re-read the cookies on the next request.

When editing, the AJAX controls tended to get confused when a session timed out. New changes give a "save work" warning 5 minutes before timeout, and force a timeout from JavaScript that exits the unattended page before the user can run afoul of the lost session.

Note that by default, JSF caches ViewState in a session so every JSF View can cause a session to be created, not just Views that reference View- or SessionScoped backing beans. This is alterable by setting an option in the faces-config. force

Developer/deployer note. Because of caching, updated installations

may not render properly. Manually request the "/main.xtml" resource and that should flush out stale info being used by "/main.jsf".
