Java Jsp页面给了我一个列表，但我的类需要一个集合

java spring jsp spring-mvc

Java Jsp页面给了我一个列表，但我的类需要一个集合,java,spring,jsp,spring-mvc,spring-form,Java,Spring,Jsp,Spring Mvc,Spring Form,我有一个名为Menu的类，有一个名为voceMenuList的字段，其中包含诸如“Home”、“contact”等菜单项通过执行以下操作，您应该能够在不使用计数器变量的情况下进行迭代： <c:forEach items="${menu.voceMenuList}" var="item"> ... URL <form:input path="${item.url}" maxlength="11"/><br/> ... </c:forEach>

我有一个名为Menu的类，有一个名为voceMenuList的字段，其中包含诸如“Home”、“contact”等菜单项

通过执行以下操作，您应该能够在不使用计数器变量的情况下进行迭代：

<c:forEach items="${menu.voceMenuList}" var="item">
...
    URL <form:input path="${item.url}" maxlength="11"/><br/>
...
</c:forEach>


...
URL

...

注意使用

var

代替

varStatus

。通过这种方式，它是一个

集合

并不重要，只要它是可伸缩的集合不维护任何顺序或索引。因此，下面的一段代码不起作用

表单：input path=“voceMenuList[${counter.index}].url“maxlength=“11”

你能试着用下面指定的方式实现你的逻辑吗

<c:forEach items="${menu.voceMenuList}" varStatus="counter" var="voicemenu">
...
    URL <form:input path="voicemenu.url" maxlength="11"/><br/>
...
</c:forEach>


...
URL

...
您在这里所做的是完全不正确地使用表单：输入
，因为路径
属性要求一个字段名称作为一个字符串，类似于模型bean的字段名称。这里有一个EL输出，它是一个url链接字符串，位于字段名的位置。难怪您会得到org.springframework.beans.InvalidPropertyException
，因为没有名为“vocementList[0]”的字段名
mmh，它看起来更像是一个nullpointerexception，位于stacktrace，在您没有包含在questionBinding中的一行代码中，它只适用于索引集合（即arrays.List）不适用于未编制索引的集合。渲染将起作用。把它转换回来是行不通的。是的，那我怎么解决这个问题呢？把它变成索引集合而不是集合。谢谢你的帮助。我已经试过了，但是我有一个错误，你可以在这里看到。我不明白哪里是错误，它不会起作用，也永远不会起作用。路径必须是属性的实际路径，在这种情况下，由于它是一个集合而不是索引集合，因此总是会失败。@Matteo您应该在表单中绑定实际路径谢谢您的帮助。我已经试过了，但是我有一个错误，你可以在这里看到。我不明白哪里是错误，它不会起作用，也永远不会起作用。路径需要是属性的实际路径，在这种情况下，由于它是一个集合而不是索引集合，因此总是会失败。和之前的答案基本相同。
