今天使用c:choose标签,一直报错:

严重: Servlet.service() for servlet CheckIncome threw exception
org.apache.jasper.JasperException: <h3>Validation error messages from TagLibraryValidator for c in /hk_life/income_balance/Balance_day.jsp</h3><p>73: Illegal text inside "c:choose" tag: " ...".</p>

网上查了一下,Illegal text inside "c:choose" tag  这个错误,只需要将c:choose标签之间的空格和换行去掉即可

报错的代码:

<c:choose>
<c:when test="${ss.result_code == 0}">
      成功
</c:when>
<c:otherwise>
     失败
   </c:otherwise>
</c:choose>

修改后的代码:

<c:choose><c:when test="${ss.result_code == 0}">成功</c:when><c:otherwise>失败</c:otherwise></c:choose>
