java - 如果其他语句不起作用的jsp

我的代码有什么问题吗？我的if else语句不起作用。

<%
String pages = request.getParameter("page");
%>
<input type="hidden" id="page" value="<%=pages%>"/>
        <div class="navbar navbar-fixed-bottom">
        <div class="navbar-inner">
            <a class="brand" href="index.jsp">PeachMangoPie</a>
            <ul class="nav pull-right">
            <li <%if(pages=="papoy"){out.write("class='active' ");}%>><a href="index.jsp?page=papoy">Papoy</a></li>
            <li class="divider-vertical"></li>
            <li <%if(pages=="chuckie"){out.write("class='active' ");}%>><a href="index.jsp?page=chuckie">Chuckie</a></li>
            <li class="divider-vertical"></li>
            <li <%if(pages=="dutchmill"){out.write("class='active' ");}%>><a href="index.jsp?page=dutchmill">Dutch Mill</a></li>
            <li class="divider-vertical"></li>
            <li <%if(pages=="icecream"){out.write("class='active' ");}%>><a href="index.jsp?page=icecream">Ice Cream</a></li>
            <li class="divider-vertical"></li>
            <li <%if(pages=="chicken"){out.write("class='active' ");}%>><a href="index.jsp?page=chicken">Chicken</a></li>
            <li class="divider-vertical"></li>
            <li <%if(pages=="straberrycake"){out.write("class='active' ");}%>><a href="index.jsp?page=strawberrycake">Strawberry-Cake</a></li>
            </ul>
        </div>
        </div>

最佳答案

您需要使用.equals方法测试字符串是否相等。
尝试以下方法：

<li <%if(pages.equals("papoy")){out.write("class='active' ");}%>><a href="index.jsp?page=papoy">Papoy</a></li>
