Custom Annotation for Logging Define an annotation to mark methods requiring logging: @Target(ElementType.METHOD) @Retention(RetentionPolicy.RUNTIME) public @interface AuditLog { String category() default ""; String action() default ""; } Log Entity Structure Create a data model for log records: @Data public class S ...

Fundamentals of Aspect-Oriented Programming Core Concepts AOP (Aspect Oriented Programming) is a programming paradigm focused on modularizing cross-cutting concerns. While OOP structures code around classes and objects, AOP concentrates on separating common functionalities—such as logging, security, or transaction management—from the core busin ...

Implementing JDBC with Spring Framework Creating a database table for student records: CREATE DATABASE STUDENT; USE STUDENT; CREATE TABLE STUDENT( ID INT PRIMARY KEY AUTO_INCREMENT, NAME VARCHAR(20) NOT NULL, AGE INT NOT NULL, SEX TINYINT(1) UNSIGNED DEFAULT 0 NOT NULL )AUTO_INCREMENT = 100000; INSERT INTO STUDENT(NAME,AGE, ...

Configuring AOP Using XML in Spring Spring supports aspect-oriented programming through both annotations and XML-based configuration. While annotation-driven AOP is more common in modern applications, XML configuration remains a viable and explicit alternative—especially in legacy or highly controlled enviroments. 1. Defining the Aspect Class T ...

IOC Section 1. Spring Ecosystem Overview Spring is a comprehensive ecosystem providing essential infrastructure for Java application development. The Spring ecosystem typically consists of: Spring Framework - the core framework Spring Boot - adds auto-configuration capability, which reads Spring Boot Starter configuration during startup, initi ...

Developers integrating Spring, SpringMVC, and MyBatis often encounter scenarios where @Transactional annotations seemingly fail, resulting in persistent database changes despite runtime exceptions. Log files typically contain the warning: JDBC Connection will not be managed by Spring, indicating the transaction advisor never intercepted the met ...

Aspect-Oriented Programing (AOP) Overview According to the Spring tutorial by King God's Spring 07: "AOP Made Simple" (qq.com) Understanding AOP Aspect-Oriented Programming (AOP) refers to a programming paradigm that enables unified maintenance of program functionalities through pre-compilation and runtime dynamic proxies. AOP exten ...

Spring is a comprehensive, open-source Java framework originally created by Rod Johnson in 2003. It is designed to simplify enterprise application development by providing a layered architecture. Spring is often described as a "one-stop-shop" (full-stack) framework because it offers solutions for various layers of an application, incl ...

Architectural Integration Strategy Persistence Layer Configuration The persistence layer is handled by MyBatis. The process begins with a configuration file, typically named SqlMapConfig.xml. To integrate this with Spring, a specific Spring configuration file (e.g., applicationContext-dao.xml) is created to manage the DAO beans. The primary c ...

In Spring Boot applications, we can enable scheduling support using the @EnableScheduling annotation and create scheduled tasks with the @Scheduled annotation. The @Scheduled annotation supports three configuration methods for execution timing: cron(expression): Executes based on a Cron expression. fixedDelay(period): Executes at fixed interva ...
