Implementing Data Masking In modern application development, protecting personally identifiable information (PII) is a critical requirement. A clean way to handle this in a Spring Boot environment is by leveraging custom Jackson annotations. This approach allows us to mask data during the JSON serialization process without adding heavy third-pa ...

System Architeecture Backend Technology Stack The system utilizes Spring Boot as the core backend framework, which follows the convention-over-configuration principle to minimize XML configuration overhead. Spring Boot automatical configures components based on project dependencies, allowing developers to focus on business logic implementation. ...

Configuring an Interceptor Register a custom interceptor by implementing WebMvcConfigurer and overriding addInterceptors. Define URL patterns to match and exclude. A global pattern such as /** also targets static resources, so explicit exclusions are necessary. @Configuration public class WebInterceptorConfig implements WebMvcConfigurer { ...

Modern enterprise architectures often involve sophisticated permission management, particularly with in platform or "middle-office" services designed to centralize common functionalities. In such a setup, user authentication and core authorization logic are frequently externalized to dedicated identity and access management (IAM) syst ...

This platform enables a community-driven waste recycling ecosystem by connecting individuals who wish to dispose of recyclable materials with authorized collection centers. The system promotes environmental sustainability by incentivizing proper waste segregation and facilitating transparent, traceable transactions between users and recycling e ...

Microservices Architecture Overview Microservices lack a strict formal definition, but the concept is best understood by contrasting it with traditional monolithic web applications. Monolithic Architecture In a traditional monolithic architecture, such as that found in early taxi-hailing software, all functional modules—passenger management, bi ...

JPA vs. JDBC Starter Dependency HierarchyThe spring-boot-starter-data-jpa artifact inherently depends on spring-boot-starter-jdbc. This establishes the JDBC starter as the foundational data access layer, while JPA operates as a higher-level abstraction built on top of it.Spring Data JPA OverviewSpring Data JPA serves as a powerful abstraction t ...

MyBatis is an open-source Java persistence framework that simplifies data base interactions by reducing JDBC boilerplate code. It supports custom SQL, stored procedures, and advanced mappings. This article covers basic CRUD operations using annotations, XML mappings, and dynamic SQL. Basic CRUD with MyBatis Start by creating a Spring Boot pr ...
