Try this: 试试这个：
<td>
<a href=<%= "\"result.jsp?Id=" + resultset.getInt(1) + "\"" %> ><%= resultset.getInt(1) %></a>
</td>

I suggest you take a look at the generated HTML. 我建议你看一下生成的HTML。 It looks like the result of the first <%=resultset.getInt(1)%> is written outside the value of the href. 看起来第一个<%=resultset.getInt(1)%>写在href的值之外。 This might work better: 这可能会更好：
<td><a href="result.jsp?Id=<%=resultset.getInt(1)%>" ><%= resultset.getInt(1) %></a></td>
On a side note I would sugest you take a look at expression language and use that instead of inlining java code in your JSP. 在旁注中我会说你看看表达式语言并使用它而不是在JSP中内联java代码。 It is hard to debug and maintain such code. 很难调试和维护这样的代码。
