One thing I love about .NET is the ability to have a database file along with the project. I know that using a SQLite database, this can be done, but did someone achieve this with a MySQL database backend?
So for instance, if I run a java program, it should be able to start its own mini MySQL server and manipulate data. So essentially, I want the same flow as with a SQLite but I need the power of MySQL.
A quick search shows this: MySQL Connector/MXJ — for embedding MySQL server in Java applications on the MySQL Downloads page at:
If you don't mind using MariaDB (the open source variant of MySQL, basically works the same) MariaDB4j can be the perfect option for production enviroments.
MariaDB4j is a Java (!) "launcher" for MariaDB (the "backward compatible, drop-in replacement of the MySQL(R) Database Server", see FAQ and Wikipedia), allowing you to use MariaDB (MySQL(R)) from Java without ANY installation / external dependencies. Read again: You do NOT have to have MariaDB binaries installed on your system to use MariaDB4j!
As it works completely without any requirements that have to be on the users' pc it is probably the best option to get MySQL embedded. Converting a project that doesn't use an Embedded database into MariaDB4j is as easy as calling:
DB db = DB.newEmbeddedDB(3306);
Read the github page for more information. Maven central dependency is:
<dependency>
<groupId>ch.vorburger.mariaDB4j</groupId>
<artifactId>mariaDB4j</artifactId>
<version>2.2.3</version>
</dependency>
If you do mind using MariaDB, another option is Wix Embedded MySQL.
Wix Embedded MySQL is a library that provides a way to run real MySql within integration tests.
Why?
- Your tests can run on production-like environment: match version, encoding, timezone, database/schema/user settings;
- Its easy, much easier than installing right version by hand;
- You can use different versions/configuration per project without any local set-up;
- Supports multiple platforms: Windows, Linux and OSX;
- Provides constantly updated multiple versions of MySql - 5.5, 5.6, 5.7;
- Testing matrix for all supported OSes (x86/x64) and versions (5.5, 5.6, 5.7).
For future reference to anyone looking to embed mysql, there is a utility from the mysql guys that does this http://downloads.mysql.com/archives/c-mxj/
It sounds like you want an embedded database. While MySQL Connector seems nice, it will launch a separate server process. If you want the database server to run in the Java virtual machine, there are several embedded databases for Java.
The two that I've seen used the most are:
