SiteMesh, SpringMVC, Shiro 配置

时间：2022-05-23 05:01:10

1. 首先在在web.xml文件中，加入SiteMesh和shiro的过滤器，保证SiteMesh的过滤器配置放在shiro的过滤器后面，不然的话，shiro的标签不能正确处理。

    </filter-mapping>

    <session-config>

        <session-timeout>30</session-timeout> <!-- 单位：分钟 -->

    </session-config>

</web-app>

2. pom.xml中引入sitemesh的依赖

    <dependency>

        <groupId>org.sitemesh</groupId>

        <artifactId>sitemesh</artifactId>

        <version>3.0.1</version>

    </dependency>

3. 在WEB-INF下加入sitemesh的配置文件(sitemesh3.xml)：

<?xml version="1.0" encoding="UTF-8"?>

<sitemesh>

    <!-- Map default decorator. This shall be applied to all paths if no other paths match. -->

    <mapping path="/*" decorator="/main.jsp" exclude="false" />

    <!-- Exclude path from decoration. -->

    <mapping path="/js/*" exclude="true" />

    <mapping path="/img/*" exclude="true" />

    <mapping path="/images/*" exclude="true" />

    <mapping path="/css/*" exclude="true" />

    <mapping path="/font-awesome/*" exclude="true" />

    <mapping path="/login" exclude="true" />

    <mapping path="/login.jsp" exclude="true" />

</sitemesh>

main.jsp 为模板页面，<mapping exlude /> 表示不经过sitemesh处理的资源和页面。

4. 模板页面的书写

在模板页面中可以使用下面的标签作为占位符：

<sitemesh:write property='title' />

<sitemesh:write property='head' />

<sitemesh:write property='body' />

被装饰的页面，可以使用自己页面中的对应部分（title, head, body），填充在这些标签的位置。

下面看一个模板页面的例子：

<%@ page contentType="text/html;charset=UTF-8" language="java" pageEncoding="UTF-8" %>

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>

<%@ taglib prefix="s" uri="http://www.springframework.org/tags" %>

<body>

  </ul>

</div>

<!--sidebar-menu-->

<!--main-container-part-->

<sitemesh:write property='body' />

<!-- end-Footer-part -->

</body>

</html>

上面的模板页面使用了：<sitemesh:write property='title' />， <sitemesh:write property='head' />，<sitemesh:write property='body' />

然后我们看下被装饰的页面：

<%@ page contentType="text/html; charset=UTF-8" %>

</script>

</body>

</html>

我们看到被装饰页面的整个 body 部分，会填充到装饰页面中的 <sitemesh:write property='body' /> 处。

正好是注释： <!--main-container-part--> 和 <!-- end-Footer-part --> 相匹配和对应。

注意：模板页面的 <sitemesh:write property='head' /> 最好放置head标签的最后面，因为被装饰页面中的head部分由可能存在依赖于模板页面中的js库。

我们看到sitemesh的使用还是十分简单的。
