Purpose

This is an introductory example into Spring Core and dependency injection, including e.g. simple REST-style services.

It contains a number of unit tests that, in the sense of test-driven development, currently fail. They can, however, easily be fixed by extending the Spring configuration.

This material has been used for a number of seminars and in introductory lecture at the University of Münster, Germany.

Requirements

• Java 8+ and an understanding of the java language and basic patterns such as the singleton and the factory pattern
• Maven 3+ or an IDE that includes appropriate support for maven builds

Rules and hints

• You do not need to change the tests to make them pass
• Spring Java-Config only, no XML required
• Autowired dependencies are acceptable only in test classes
• Prefer centralised constructor injection over setter-injection or annotation based DI configurations
• All tests can be started (and passed) independently
• Tests may not interfere with each other
• Do not access the bean factory or context classes directly (i.e. using anything along the lines of a getBean(..)-Statement is prohibited)
