大家好（就像其他人一樣）繼承了一些struts 1代碼。我需要爲此項目添加更多頁面。Struts 1 ActionForm - 從純HTML中檢索集合
我無法弄清楚的是如何映射幾個不同但類似性質的輸入元素到我的ActionForm中。
讓我詳細說明。我在用戶輸入越來越多的項目時動態地創建了一個新的<Input>元素（我使用YUI自動完成表單元素，並且對於每個輸入的輸入，我將它作爲輸入元素添加到我的表單並繪製新的YUI自動完成 - 複雜的聲音，我知道）
所以......我的形式看起來有點像（...一些美化後一些這樣的...）：

我的stuts-config的相關部分。 xml文件是：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">
<struts-config>
<data-sources />
<form-beans>
<form-bean name="TestCaseForm" type="com.blahblah.mycoolapp.forms.TestCaseForm" />
</form-beans>
<action-mappings>
<action path="/pages/SaveTestCase" name="TestCaseForm"
type="org.springframework.web.struts.DelegatingActionProxy" scope="request">
</action>
</action-mappings>
<message-resources parameter="MessageResources" />
</struts-config>
我也用彈簧2.56（相關部分是）：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean name="/pages/SaveTestCase" class="com.blahblah.mycoolapp.actions.TestCaseBuilderSaveAction" />
</beans>
我的Java ActionForm類（從我所學過的淨值）爲：
package com.blahblah.mycoolapp.forms;
import java.util.ArrayList;
import java.util.List;
import org.apache.struts.action.ActionForm;
public class TestCaseForm extends ActionForm {
private static final long serialVersionUID = 2352146257739099766L;
private String scenario;
private String ruleID;
private String testCaseName;
private List<String> SelectedRows = new ArrayList<String>() ;
public String getScenario() {
return scenario;
}
public void setScenario(String scenario) {
this.scenario = scenario;
}
public String getRuleID() {
return ruleID;
}
public void setRuleID(String ruleID) {
this.ruleID = ruleID;
}
public String getTestCaseName() {
return testCaseName;
}
public void setTestCaseName(String testCaseName) {
this.testCaseName = testCaseName;
}
public List<String> getSelectedRows() {
return SelectedRows;
}
public void setSelectedRows(int index, String value) {
this.SelectedRows.add(value);
}
}
問題是爲什麼我在我的TestCaseBuilderSave Action中獲得一個空的SelectedRows？
感謝所有誰有耐心看完這麼長的問題...
和（希望）感謝你的潛在救星:)
編輯1：
由於爲了@ ahiru的請求我發佈了我的行動課程 - 暫時只是一個簡單的過程。幾乎什麼都不做，類：
public class TestCaseBuilderSaveAction extends Action {
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request,
HttpServletResponse response) throws Exception {
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","attachment;filename=superfish.xml");
try
{
ServletOutputStream out = response.getOutputStream();
String contentStr = "<Yaneeve>Has been here...</Yaneeve>";
byte[] bytes = contentStr.getBytes();
out.write(bytes, 0, bytes.length);
out.flush();
out.close();
}catch(Exception e){
e.printStackTrace();
}
return null;
}
}
謝謝，我已經嘗試了兩件事......既沒有你提出的方法，也沒有陣列的工作。就我而言，它可能是一個List，一個數組，一個Map，一個圖，不管...只要我使用ActionForm獲取數據到服務器 – Yaneeve 2010-06-16 12:51:50
將給你的數組示例另一個嘗試...... – Yaneeve 2010-06-16 13:18:05
@ahiru：至於「我也很好奇，如果春天和struts一起玩很好（我沒有做過這方面的研究）」我只有整合了struts 1與春天，而不是struts 2，但從我短暫的經驗，初始設置是有點棘手，但從那時起（大部分）是平穩的航行 – Yaneeve 2010-06-16 13:19:47
