jsp报错问题之“使用jstl的c标签choose报错Illegal text inside "c:choose" tag问题”

一.报错

[bessky_it][ERROR][2022-03-25 17:19:07] | PLATFORM | ):[c]鍜孾/com.bessky.pss.portal/purchase/sample_apply_add.jsp]鐨凾agLibraryValidator鐨勯獙璇侀敊璇秷鎭�66: Illegal text inside "c:choose" tag: " | URL=sample/applys/create | com.bessky.platform.filter.RequestContextFilter.doFilterInternal(RequestContextFilter.java:117)

二.问题代码

<c:choose>
   <!--获取登录人部门 = 209或 获取登录人部门 = 245-->
   <c:when test="${sessionScope.authenticated_user.department.departmentId == 209 ||sessionScope.authenticated_user.department.departmentId == 245}">
      <app:select required="required" classes="input-medium" items="${domain.applyUsers }" listkey="userId" listvalue="display" headkey="1" headvalue="王子威" name="sampleApply.purchaseBy" select2="true"></app:select>
   </c:when>
   <c:otherwise>
      <app:select required="required" classes="input-medium" items="${domain.applyUsers }" listkey="userId" listvalue="display" headkey="" headvalue="" name="sampleApply.purchaseBy" select2="true"></app:select>
   </c:otherwise>
</c:choose>

三.原因

因为注释问题：<!--获取登录人部门 = 209或 获取登录人部门 = 245-->导致的报错

去掉注释就好了（并非所有人有效）
