`<c:forEach var="keyword" items="${keywords}">`
`<c:set var="test1">${keyword}</c:set>`
`<c:out value="${bulkAssayDetails[test1]}" />`
`<c:forEach var="assaydetails" items="${bulkAssayDetails[test1]}"> `
`</c:forEach>'
`</c:forEach>`
${keywords}
是一套
在c:我可以打印该值
对于第二个c:forEach得到以下错误javax.servlet.jsp.JspTagException: Don't know how to iterate over supplied "items" in <forEach>
