Spring Framework Lecture Notes

---

1. Introduction

• Discussion on the Spring Framework.
• Various topics will be covered such as beans, software requirements, configuration file, and dependency injection.

2. Required Software

• The following software will be required to start the project experimentally:
  • IDE (like Eclipse, NetBeans, IntelliJ IDEA)
  • Tomcat Server (for web projects)
  • MySQL (for the database)

3. Project Setup

• Creating a Maven Project:
  • Create a new Maven project in Eclipse.
  • Choose Maven Archetype: Quickstart.
  • Name the project (e.g., com.spring).

3.1. Adding Dependencies

• Include the necessary dependencies in the project:
  • Spring Core
  • Spring Context
• Dependencies are added in the POM.xml file.

4. Creating Java Bean

• Create a simple POJO class (Java Bean):
  • Include properties, getters, and setters.
  • Example: Student class with properties for name, ID, and address.

5. Creating Configuration File

• An XML file (config.xml) needs to be created.
• Define Spring Beans in this file:
  • Declare classes using the <bean> tag.
  • Set property values (Setter Injection).

6. Dependency Injection

• The Spring Container (IOC Container) will create the objects and manage their lifecycle.
• Set property values and obtain objects through configurations.

7. Conclusion

• Setting up everything at once simplifies many processes.
• In the next class, we will look at Constructor Injection and Reference Types.

8. Important Points

• Any changes can only be made in the configuration file, not in the Java code, making maintenance easier.

9. Video Length

• The video is long but important and informative.
