我正在得到

org.apache.jasper.JasperException：/WEB-INF/AllClientBatchDetails.jsp(54,103) 需要等号

这是我将请求属性设置为batchProgressMetricsList 的jsp

及其调用的对象的数组列表。我有 AggregateBatchProgressMetrics。在 AggregateBatchProgressMetrics 内部，我有一个名为 getBatchMetricsList 的方法，它返回一个名为 BatchProgressMetrics 的对象的数组列表。如果我在没有嵌套的 c:forEach 标签的情况下运行它，它会运行得很好，但如果我包含嵌套的标签，它就会失败。有人可以帮我吗？

提前致谢。阿尔马斯

I have request attribute set to batchProgressMetricsList and its an array list of an object called. I have AggregatedBatchProgressMetrics. Inside aggregatedBatchProgressMetrics i have a method called getBatchMetricsList which return an arraylist of object called BatchProgressMetrics. If i run it without the nested c:forEach tag, it would just run fine, but if i include the nested one it just fails. Can somebody please help me?

Thanks in advance.

尝试将其更改

items="${aggregatedBatchProgressMetrics["batchMetricsList"]}"

为：

items="${aggregatedBatchProgressMetrics['batchMetricsList']}"

Try changing this:

items="${aggregatedBatchProgressMetrics["batchMetricsList"]}"

to this:

items="${aggregatedBatchProgressMetrics['batchMetricsList']}"

替换

<c:forEach var="batchProgressMetrics" items="${aggregatedBatchProgressMetrics["batchMetricsList"]}">

为

<c:forEach var="batchProgressMetrics" items="${aggregatedBatchProgressMetrics['batchMetricsList']}">

双引号过早关闭 items 值，导致 EL 无效。当使用具有良好 sytnax 突出显示功能的编辑器时，您应该很快就发现了这一点（就像这里的 SO :) ）。

Replace

<c:forEach var="batchProgressMetrics" items="${aggregatedBatchProgressMetrics["batchMetricsList"]}">

<c:forEach var="batchProgressMetrics" items="${aggregatedBatchProgressMetrics['batchMetricsList']}">

The doublequote was closing the items value too soon which resulted in invalid EL. You should have spotted this soon enough when using an editor with decent sytnax highlighting (like here on SO :) ).
