Spring is a popular Java-based framework for developing large-scale enterprise-level applications both on and off the web. It is based on the dependency injection design pattern and allows for building decoupled applications. It has grown in popularity over the years due to this nature and the number of supported projects that are still ongoing. Spring also provides support for connection to databases using both JDBC methods and object-relational mapping libraries such as Hibernate.
This course starts with how to set up simple Spring projects and define beans. We then move on to web-based MVC projects. Persistence and transactions are covered, looking at both JDBC and Hibernate ORM implementations. Finally, we cover how to secure an application, including authentication methods and user roles.
The course will be taught as a series of presentations, walk-through examples and exercises to complete. The exercises start as walkthroughs to build basic Spring projects, but by the end free reign is given to design and write larger web applications based on a given scenario. Previous experience of using standard Java is essential, and experience of using databases and writing simple queries will also be required.
- Essential: Familiarity with object-oriented programming in Java
- Essential: Familiarity with basic database operations and some experience with SQL
