Decoupling Lead Notifications with the Observer Pattern in Java
Introdução O Observer Pattern (Padrão Observador) é um padrão de projeto comportamental , ou seja, ele trata de como os objetos se comunicam e distribuem responsabilidades entre si em tempo de execução — diferente dos padrões criacionais (que tratam de como objetos são instanciados) ou estruturais (que tratam de como objetos se compõem). A ideia central é simples: um objeto, chamado Subject (ou…
The article discusses the Observer Pattern, a behavioral design pattern that allows objects to communicate and distribute responsibilities at runtime. It describes a scenario where a lead capture service needs to trigger multiple actions, such as synchronizing with a CRM, notifying sales teams, and sending welcome emails. The Observer Pattern solves the problem of tight coupling by allowing interested objects to subscribe to receive notifications, rather than having the emitter know who needs to be notified.
The article provides a Java implementation of the pattern, using a LeadCaptureService as the subject and four observers: CrmSyncObserver, SalesNotifierObserver, WelcomeEmailObserver, and AnalyticsObserver.
