Chapter 2: Why Spring Boot over Spring? | Spring Boot Course
Previous Chapter:
Introduction
The Spring Framework is a powerful framework for building enterprise Java applications, but it can be complex and challenging to work with. Common issues include the need for extensive configuration, managing dependencies, deployment complexities, and handling boilerplate code. Spring Boot was created to solve these problems, making it easier for developers to build, run, and maintain Spring applications.

Problems with Using Spring Framework and How Spring Boot Solves Them
Problem 1: Complexity in Configuration
Issue: Traditional Spring applications require a lot of configuration. This can include setting up beans, data sources, transaction management, and more. This complexity can slow down development and make it harder to manage the application.
Solution: Spring Boot uses autoconfiguration to handle most of these settings automatically. By including the right dependencies, Spring Boot can set up default configurations for you.
Example: Setting up a data source
Without Spring Boot:
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
@Configuration
public class DataSourceConfig {
@Bean
public DriverManagerDataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost:3306/mydb");
dataSource.setUsername("user")…
