【问题描述】：
我有一个这样的豆子
private String projectName;
private String projectCode;
它包含有效的 getter 和 setter。
在我的 Action 类中，我将它作为 List 返回并进一步传递给 JSP 以显示。
<select class="ibm-styled" name="selectedProjects" id="selectedProjects"
multiple="multiple" tabindex="1">
<s:iterator value="projectList">
<option value="<s:property value='projectCode' />">
<s:property value="projectName"/>
</option>
</s:iterator>
</select>
从 JSP 中的这段代码中，我得到了 selectedProjects 中选定项目代码的列表，并且它们在表单提交后被设置回 Action 类。
现在，在动作类中，我需要迭代这个选定的项目并在某个字符串中获取所有项目名称......我已经编写了这样的代码
if (selectedProjects != null) {
String[] selectedProjectsId = selectedProjects.split(", ");
StringBuffer ProjNames = new StringBuffer();
Iterator<Project> iterator = projectList.iterator();
while (iterator.hasNext()) {
Project beanFromList = iterator.next();
for (int ProjId = 0; ProjId < selectedProjectsId.length; ProjId++) {
if (beanFromList.getProjectCode().equals(
selectedProjectsId[ProjId])) {
ProjNames.append(beanFromList.getProjectName()).append(
", ");
}
}
}
System.out.println(ProjNames);
}
上面的代码没有错误，所有的声明都是正确的……我只能在最后提到的sn-ps中更改我的代码，其余的我不能碰。
我在日志中遇到以下异常......
E ArchiveInputStreamData iterate unable to open file iterator
不知道它是否有效。当执行到达声明迭代器的行时，我确实开始出现调试问题。
请帮帮我！

【问题讨论】：
-
我们看不到您的代码——我们不知道
projectList是什么，因此无法提供帮助。我建议使用标准 Java 命名约定（例如，ProjNames命名错误）和一致的缩进以使内容更易于阅读。 -
如果您在与此问题相关的日志中有错误，那么您应该发布完整的堆栈跟踪。如果没有，就很难理解您的错误消息、错误消息发生的原因和位置。
-
projectList 是我在上面提到的 Bean 类型的数组列表......唯一发生的问题是在使用 Project 类型的迭代器时。我也在添加 StackTrace of Exception
