核心屬性詳解

版本管理最佳實踐

• 無版本號 XSD：spring-beans.xsd 自動匹配當前 Spring 版本（推薦）
• 指定版本：spring-beans-5.3.xsd 鎖定版本，升級需手動修改
• 本地解析：Spring JAR 包 META-INF/spring.schemas 映射本地 XSD，離線也能驗證

常用命名空間速查表

<!-- 數據訪問 -->
xmlns:jdbc="https://www.springframework.org/schema/jdbc"
xmlns:jpa="https://www.springframework.org/schema/data/jpa"

<!-- 任務調度 -->
xmlns:task="https://www.springframework.org/schema/task"

<!-- 消息隊列 -->
xmlns:jms="https://www.springframework.org/schema/jms"

<!-- 安全框架 -->
xmlns:security="https://www.springframework.org/schema/security"

IDE 智能提示配置

IntelliJ IDEA：Settings → Schemas and DTDs → 添加 Spring XSD 映射
Eclipse：Preferences → XML → XML Catalog → Add User Entry
