Spring @Required Annotation Example

Date: 2018-09-09

This tutorial demonstrates Spring's @Required annotation, which mandates bean property setter injection. Applying @Required to a setter method ensures that the corresponding property receives a value during configuration. The annotation's activation requires including <context:annotation-config/> or defining RequiredAnnotationBeanPostProcessor in the Spring configuration file. Failure to inject a required property throws a BeanInitializationException. The tutorial provides a step-by-step guide with code examples, including setting up a Maven project and configuring dependencies.
