  • 返回JSON: Action中通过 ServletActionContext.getResponse().getWriter() 直接输出JSON
    • +
  • 不返回result: AJAX Action返回 NONE，不经过视图层
    • +
  • 异步验证: 使用 onblur 事件触发AJAX验证，提升用户体验
    • +
  • 定时刷新: 使用 setInterval 实现实时数据监控
    • +

    +
  • 类加载器层次: Bootstrap → Extension → Application → WebApp，形成双亲委派模型
    • +
  • 双亲委派: 类加载时先委托父加载器，父加载器无法加载时才自己加载
    • +
  • 加载过程: 加载 → 验证 → 准备 → 解析 → 初始化，五个阶段确保类正确加载
    • +
  • Struts2类加载: 框架类由Application加载器加载，应用类由WebApp加载器加载

📚 学习要点

+
    +
  • 文件字段命名: 表单中的文件字段名必须与Action中的属性名一致（如 upload）
    • +
  • 三个属性: Action需要提供 File upload、String uploadFileName、String uploadContentType
    • +
  • 多文件上传: 使用数组形式 File[] uploads、String[] uploadsFileName 等
    • +
  • 表单enctype: 必须设置 enctype="multipart/form-data"
    • +
  • 文件验证: 可以在 validate() 方法中检查文件大小和类型
    • +
  • 文件保存: 使用 FileUtils.copyFile() 或手动流操作保存文件
    • +
+ +
+ 💡 提示 +
    +
  • 上传的文件默认保存在临时目录，需要手动移动到目标位置
    • +
  • 建议生成唯一文件名避免冲突（如使用UUID）
    • +
  • 生产环境应该限制上传目录的访问权限
    • +
  • 大文件上传需要考虑分片上传和进度显示

  • 请求入口: 所有请求先经过StrutsPrepareAndExecuteFilter过滤器
    • +
  • ActionProxy: 封装Action的调用信息，包含拦截器栈配置
    • +
  • 拦截器链: 使用责任链模式，前置处理顺序执行，后置处理逆序执行
    • +
  • 值栈: OGNL表达式的根对象，包含Action和上下文数据
    • +
  • 结果渲染: 根据返回字符串查找对应的Result进行视图渲染
    • +
  • 线程安全: 每个请求创建新的Action实例，不存在线程安全问题

  • 值栈根对象: Action对象默认在值栈顶部，可以直接访问其属性
    • +
  • OGNL上下文: 包含request、session、application等Web对象
    • +
  • 类型转换: OGNL自动进行字符串到目标类型的转换
    • +
  • 集合操作: 支持过滤(?)、投影(.{})、选择(^/$)等高级操作
    • +
  • Lambda支持: 可以使用Lambda表达式进行复杂操作
    • +
  • 安全性: OGNL功能强大，注意防范OGNL注入攻击

🛡️ Struts2 拦截器演示

+ +
+ 实验观察点： +
    +
  • 连续刷新页面，观察 Action 调用次数如何累积
    • +
  • 切换到“API 限流栈”，理解为什么拦截器顺序会影响结果
    • +
  • 注意执行时间显示，这就是拦截器注入到 request 的数据
    • +
+
+ +
+

📊 执行统计

+

本次请求执行时间: ms

+ +

Action 调用统计:

+ + + + + + + + +
Action调用次数
+
+ +
+

🔗 拦截器链演示

+

当前使用: customStack (日志 + 计时 + 监控 + 默认栈)

+ 使用 API 限流栈 +

API 栈包含: 日志 + 限流 + 验证 + 计时 + 默认栈

+
+ +
+

📚 拦截器执行顺序

+ 
+请求 → LoggingInterceptor → TimingInterceptor → MonitorInterceptor → Action
+响应 ← LoggingInterceptor ← TimingInterceptor ← MonitorInterceptor ← Result
+
+

注意: 拦截器像洋葱一样，先进入的后退出

+
+ +
+

💡 拦截器核心概念

+
    +
  • Interceptor 接口: init() → intercept() → destroy()
    • +
  • intercept() 方法: 调用 invocation.invoke() 继续链
    • +
  • 拦截器栈: 多个拦截器按顺序组成链
    • +
  • 责任链模式: 每个拦截器决定是否继续
    • +

🛡️ 拦截器 (核心特性)

+

拦截器是 Struts2 最强大的特性之一，基于责任链模式实现 AOP。

+ + +
+ +
+

📝 基础示例

+ +
+ +

📚 学习路径

+ +
+

1. MVC 架构

+
    +
  • Model: Action 类 + JavaBean
    • +
  • View: JSP + Struts 标签库
    • +
  • Controller: StrutsPrepareAndExecuteFilter
    • +
+
+ +
+

2. 拦截器机制

+
    +
  • Interceptor 接口: init() → intercept() → destroy()
    • +
  • interceptor-stack: 组合多个拦截器
    • +
  • 执行顺序: 责任链模式（先入后出）
    • +
+
+ +
+

3. OGNL 表达式

+
    +
  • <s:property value="name"/> - 输出属性
    • +
  • <s:iterator value="list"> - 遍历集合
    • +
  • #request.key - 访问 request
    • +
+
+ +
+

4. 项目结构
