本文介绍了一个使用Struts2框架实现的表单处理示例，通过自定义的AutoArrayList类实现了动态表单元素的创建与更新。具体展示了如何在Action中设置和获取表单数据，并在JSP页面上利用Struts标签库进行表单元素的迭代显示。

ActionForm:

public List checkResultList = new AutoArrayList(SourceCodeCheckResult.class);

	public List getCheckResultList() {
		return checkResultList;
	}


	public void setCheckResultList(List checkResultList) {
		this.checkResultList.clear();
		this.checkResultList.addAll(checkResultList);
	}

AutoArrayList

import java.util.ArrayList;

public class AutoArrayList extends ArrayList {
	private Class itemClass;

	public AutoArrayList(Class itemClass) {
		this.itemClass = itemClass;
	}
	public Object get(int index) {
		try {
			while (index >= size()) {
				add(itemClass.newInstance());
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
		return super.get(index);
	}
}

页面上代码:

<logic:iterate id="checkResultList" name="requestForm" property="checkResultList" indexId="logId">
		    <tr>
		        <td><bean:write property="lineNo" name="checkResultList" /></td>
		        <td>
		        	<bean:define id="rule" name="checkResultList" property="rule" />
		        	<a href="#" class="clickTip"  ruleid='<bean:write property="id" name="rule" />' />
		            #<bean:write property="id" name="rule" /> <bean:write property="name" name="rule" />
		            </a>
		        </td>
		        <td>
		        <html:hidden property="logId" name="checkResultList" indexed="true"/>
		        <html:textarea property="reason" cols="5" rows="10" name="checkResultList" indexed="true"/></td>
		        <td><html:textarea property="comment" cols="5" rows="10" name="checkResultList" indexed="true"/></td>
		        <td>
		        	<html:select name="checkResultList" property="reason" onchange="checkHistoryReason()">
                        <html:option value="">----Please Select one -----</html:option>
                        <logic:notEmpty  property="history" name="checkResultList">
                        	<html:options property="history" name="checkResultList"/>
                        </logic:notEmpty>                        
                     </html:select>	        
		        </td>
		    </tr>
		</logic:iterate>

Action代码:

RequestForm requestForm = (RequestForm)form;
	  List updateData = requestForm.getCheckResultList();
	  SourceCodeCheckDao dao = (SourceCodeCheckDao) SpringBeanFactory
	    .getBean(SourceCodeCheckDao.ROLE);
	  	boolean pass = dao.updateCheckRusultList(updateData);
