+  "summary": "Replace verbose Spring XML bean definitions with concise annotation-driven configuration in Spring Boot.",
+  "explanation": "Traditional Spring applications wired beans through XML configuration files, declaring each class and its dependencies as verbose <bean> elements. While annotation support existed since Spring 2.5, XML remained the dominant approach until Spring Boot introduced auto-configuration. Spring Boot detects beans annotated with @Component, @Service, @Repository, and @Controller via classpath scanning, satisfies dependencies through constructor injection automatically, and configures infrastructure like DataSource from the classpath — eliminating all XML wiring files.",
