This tutorial explains how to generate PDF files in Java using the iText library, covering dependency setup, a simple "Hello World" PDF example, converting complex HTML pages to PDF, and dynamic content insertion with Freemarker templates.
This article walks through why repetitive CRUD code wastes development time, reviews existing generators like MyBatis‑Generator and MyBatis‑Plus, and then demonstrates step‑by‑step how to create a custom Java code generator using Freemarker, Maven, and SpringBoot, complete with template and demo code.
This article walks through creating a fully automated Spring Boot and MyBatis code generator using Freemarker templates, detailing each step from extracting table metadata to generating DAO, service, controller, and entity classes, and shows how a single-table CRUD can be produced in seconds.
This guide walks through the need for PDF generation in business scenarios, introduces the iText library (both iText5 and iText7), shows how to add Maven dependencies, provides a minimal “Hello World” PDF example, then details converting HTML (with CSS, images, and Freemarker variables) into PDF, and discusses when custom adaptation is required.
This tutorial demonstrates how to integrate OpenHtmlToPdf with a Spring Boot 3.2.8 application, using Freemarker templates and custom fonts to render HTML content and deliver high‑quality PDF files via a REST endpoint, complete with code examples and configuration details.
This article explains how to design a backend architecture that pre‑generates article HTML with FreeMarker, stores files on cloud servers, caches data in Redis and local memory, and uses LVS, Nginx, and Sentinel to safely handle sudden traffic spikes from viral news.
This article examines injection vulnerabilities in Java template engines Velocity, FreeMarker, and Thymeleaf, details payload extraction, demonstrates how to generate automated detection rules and security operation capabilities, and discusses future directions for comprehensive attack‑chain analysis.
