Objectives
- Understand the core principles of Spring, and of Dependency Injection (DI) / Inversion of Control

- Know the different types of metadata (XML, annotations/@Component, and Java Configuration/@Configuration), and how and when to use them
- Understand and use the complete capabilities of the Core module, such as lifecycle events, bean scopes, and the Spring API
- Use Spring Boot to simplify dependency management and configuration
- Understand and use Boot’s auto-configuration
- Customize Boot’s behavior with properties and in other ways
- Work with the ORM (Object-Relational Mapping) module to integrate Spring with technologies such as JPA
- Use Spring Data to automatically generate JPA-based repository classes
- Understand and use Spring’s transaction support, including the easy-to-use Java annotation support
- Understand REST, and use Spring REST to build RESTful services
- Use Ajax-based front ends with Spring REST
- Use RestTemplate to create Java REST clients
Prerequisites
All attendees must have at least one year of full-time Java and JSP development experience. Prior experience with servlets and JSP is recommended but not required.
