页眉和页脚的JSP代码结构很好

我目前有以下JSP页面的代码结构:

MyPage.jsp

<jsp:include page="header.jsp"/>
Specific page content
<jsp:include page="footer.jsp"/>

但是,这意味着页眉和页脚代码没有正确的HTML结构。例如,这是简化的页眉和页脚代码:

header.jsp中

<!DOCTYPE html>
<html lang="en">
    <head>
        <title>${param.pageTitle}</title>
    </head>
    <body>
        <div class="container" style="margin-top: 80px;">

footer.jsp中

        </div>
    </body>
</html>

因此,IDE会发出关于&#34;缺少开始标记的警告&#34; /&#34;缺少结束标记&#34;。我不会完全禁用警告,因为它可能会发现HTML结构的合法问题。

是否有更简洁的方法来构建JSP代码,以便我仍然可以以一种好的方式重用页眉和页脚代码?

这可能会有所帮助。请看看。

\home.jsp               // Base Page
\parts\meta.jsp         // To hold page meta information. Useful when working with SEO
\parts\header.jsp       // Resources CSS, images, 
\parts\footer.jsp       // Resources JS

记住

Use <%@include> because it is static include and <jsp:include> is dynamic include. When you use <jsp:include> the file will be included at runtime. When you use <%@include> file will be included at compile time.

所以这里是代码片段。

1)home.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<%@ include file="parts/meta.jsp" %>  
<title>Home Page</title>
<%@ include file="parts/header.jsp" %>  
</head>
<body>
    <div class="view">
        <div class="pages">
            <jsp:include page="parts/page-body.jsp"></jsp:include>
        </div>
    </div>
    <%@ include file="parts/footer.jsp" %>  
</body>
</html>

2)meta.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<meta charset="utf-8">
<meta name="viewport"
    content="width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no, minimal-ui">
<meta name="mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-status-bar-style" content="black">

3)header.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<link href="http://fonts.googleapis.com/css?family=Roboto:400,300,500,700" rel="stylesheet" type="text/css">
<link rel="stylesheet" href="css/my-page.css">
<link rel="stylesheet" href="css/my-icon.css">
<link rel="icon" href="img/icon.png">

4)footer.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<script type="text/javascript" src="js/my-app.js"></script>
<script type="text/javascript" src="js/my-app-service.js"></script>

谢谢:)

您正在做的是完全错误的编程方式。我们使用include标签在另一个页面中插入一个完整的页面。我们不会将页面分成几部分。因此,正确的方法应该是在主jsp页面中包含两个单独的jsp页面作为页眉和页脚而不会扭曲它。那是你的MyPage.jsp应该是: -

<!DOCTYPE html>
<html lang="en">
    <head>
        <title>${param.pageTitle}</title>
    </head>
    <body>
         <jsp:include page="header.jsp"/>
             Specific page content
         <jsp:include page="footer.jsp"/>
    </body>
</html>

并且header.jsp和footer.jsp应该是: -

<!DOCTYPE html>
<html lang="en">
    <head>
    </head>
    <body>
          Specific page content
    </body>
</html>

这是页面的正确结构。
