Struts和Sitemesh整合,實現多個裝飾器

web.xml配置

<filter>
    <filter-name>struts-prepare</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter</filter-class>
</filter>

<filter>
    <filter-name>sitemesh</filter-name>
    <filter-class>com.opensymphony.sitemesh.webapp.SiteMeshFilter</filter-class>
</filter>

<filter>
    <filter-name>struts-execute</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>struts-prepare</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<filter-mapping>
    <filter-name>sitemesh</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<filter-mapping>
    <filter-name>struts-execute</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

注意: <filter-mapping>的順序必須是以上順序,struts-prepare-->sitemesh-->struts-execute.不然的話裝飾器不會起做用.

Sitemesh xml配置

<!-- 配置裝飾器 -->
<decorators defaultdir="/WEB-INF/decorators"><!-- 裝飾器頁面目錄 -->
    <!-- 不裝飾的頁面 -->
    <excludes>
        <pattern>/login.jsp</pattern>
        <pattern>/qiantai/userinfo/*</pattern>
        <pattern>*My97DatePicker.htm</pattern> 
    </excludes>
    
    // 這個裝飾器裝飾那個路徑下的, 這裏能夠配置多個裝飾器
    <decorator name="main" page="houtai/main.jsp">
        <pattern>/*</pattern>
    </decorator>
    <decorator name="menu" page="houtai/menu.jsp" />
    <decorator name="header" page="houtai/header.jsp" />
    <decorator name="footer" page="houtai/footer.jsp" />
    
    // 前臺裝飾樣式
    <decorator name="qt_main" page="qiantai/main.jsp">
        <pattern>/qiantai/*</pattern>
    </decorator>
    <decorator name="qt_header" page="qiantai/header.jsp" />
    <decorator name="qt_footer" page="qiantai/footer.jsp" />
</decorators>

注意: 裝飾器配置時不一樣裝飾器中<decorator>標籤中的name屬性的值不能同樣,不然會出現裝飾頁面混淆的狀況.
