输入字符串的 NumberFormatException

发布于 2024-10-06 22:20:36 字数 15854 浏览 7 评论 0原文

我在 JSF 支持 bean 中有以下方法：

public List<Rent> getTopMemebers(){
    return rentDAO.findByMonthAndYear(MonthReport, YearReport);
}

我在数据表中显示它：

<p:dataTable value="#{rentController.topMemebers}" var="item">
    <p:column>
        <h:outputText value="#{item.rentid}"/>
    </p:column>
    ...
</p:dataTable>

但我得到以下异常：

它是如何引起的以及如何修复它？\

原文

I have the following method in a JSF backing bean:

I am displaying this in a datatable:

    <p:column>
        <h:outputText value="#{item.rentid}"/>

那么，

<h:outputText value="#{item.rentid}" />

造成这种情况的原因是：

java.lang.NumberFormatException: For input string: "rentid"
    ...
    at javax.el.ArrayELResolver.getValue(ArrayELResolver.java:195)
    ...
    at javax.faces.component.UIOutput.getValue(UIOutput.java:168)

您是否正在运行您认为正在运行的代码？堆栈跟踪中 ArrayELResolver 的参与表明 #{item} 实际上是一个类似于 Object[] 的数组。数组值只能通过整数索引（如 #{item[0]}）获取，但您可以使用字符串 rentid 作为 #{item .rentid} 导致了这个异常。

确保 RentController#getTopMembers() 返回 List，而不是 List 并且 的版本正确code>RentController 被声明为 #{rentController} 托管 bean。

So,

<h:outputText value="#{item.rentid}" />

is causing this:

java.lang.NumberFormatException: For input string: "rentid"
    ...
    at javax.el.ArrayELResolver.getValue(ArrayELResolver.java:195)
    ...
    at javax.faces.component.UIOutput.getValue(UIOutput.java:168)

Are you running the code you think you're running? The involvement of ArrayELResolver in the stacktrace indicates that #{item} is actually an array like Object[]. Array values can only be obtained by an integer index like #{item[0]}, but you're accessing it with a string rentid as #{item.rentid} which caused this exception.

Ensure that RentController#getTopMembers() returns a List<Rent>, not List<Object[]> and that the correct version of RentController is been declared as #{rentController} managed bean.
