<h1>属性绑定与 ModelDriven 绑定怎么理解</h1>
<p>这页用来解释 Struts2 如何把请求参数装配进 Action。建议配合用户资料表单和字段校验实验一起看。</p>
<h2>Property-driven</h2>
<h2>属性驱动绑定</h2>
<ul>
<li>Define simple fields directly on the action.</li>
<li>Expose setters and getters for each form field.</li>
<li>Great for short demos and small forms.</li>
<li>直接在 Action 上定义简单字段。</li>
<li>为表单字段提供对应的 setter / getter。</li>
<li>适合短流程 Demo 和小型表单。</li>
</ul>
<h2>Model-driven</h2>
<h2>ModelDriven 绑定</h2>
<ul>
<li>Return a dedicated model object from <code>getModel()</code>.</li>
<li>Keep request data separate from action orchestration logic.</li>
<li>Better for larger forms and nested objects.</li>
<li>通过 <code>getModel()</code> 返回一个独立模型对象。</li>
<li>把请求数据和 Action 编排逻辑拆开。</li>
<li>更适合复杂表单和嵌套对象。</li>
