Unreachable code
我的 JSP页面中有段代码如下：
<div class="content">
<ul class="class_date">
<li id="class_month">
<%
TopicBiz tb=new TopicBizImpl();
List<Topics> topics=tb.getTopics();
request.setAttribute("topics",topics);
String topicId=request.getParameter("ntid");
if(topicId==null) response.sendRedirect("Index.jsp");
return;
%>
<c:forEach var="topic" items="${topics}" varStatus="status">
<a href="CIndex.jsp?ntid=${topic.tid}"><b><c:out value="${topic.tname}"></c:out></b></a>
</c:forEach>
An error occurred at line: 170 in the jsp file: /pages/CIndex.jsp
Unreachable code
167: String topicId=request.getParameter("ntid");
168: if(topicId==null) response.sendRedirect("Index.jsp");
169: return;
