Facelets继承

Question

我想使用 Facelets 从基本模板继承，但我不知道该怎么做；我在同一个文件夹中有两个文件：base.xhtml 和 login.xhtml 我希望 login.xhtml 继承自 base.xhtml，我应该包含任何库以进行简单继承吗？我想要的只是覆盖 login.xhtml 上的标题标签和 body 标签；

base.xhtml :

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:ui="http://java.sun.com/jsf/facelets">
    <h:head>
        <title><ui:insert name="titre" /></title>
        <link type="text/css" rel="stylesheet" href="resources/css/bootstrap.css"></link>
        <link type="text/css" rel="stylesheet" href="resources/css/tether.min.css"></link>
        <script type="text/javascript" src="resources/js/jquery.js"></script>
        <script type="text/javascript" src="resources/js/tether.min.js"></script> 
        <script type="text/javascript" src="resources/js/bootstrap.js"></script>
        <script type="text/javascript" src="resources/js/sortable.js"></script>

    </h:head>
    <h:body>

    </h:body>
</html>

Answer 1

模板页面，即 template_name.xhtml 通常放在 WEB-INF 文件夹中，可能在您新创建的文件夹下，如下所示：

--WEB-INF 
    |--templates
        |--template.xhtml

template.xhtml:

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
      xmlns:f="http://xmlns.jcp.org/jsf/core">

    <h:head>
      <ui:insert name="tabTitle">
          Some default title
      </ui:insert>

      // normally you leave spaces for you to define external resources
      <ui:insert name="css" />
      <ui:insert name="js" />

    </h:head>
    <h:body>

      <ui:insert name="body">
           Default content
      </ui:insrt>               

    </h:body>
</html>

然后，每当您想使用上方模板时：

some_page.xhtml

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
      xmlns:f="http://xmlns.jcp.org/jsf/core"

      template="/WEB-INF/templates/template.xhtml">


    // the just override any <ui:insert /> tag you want by setting the
    // name="" attribute to which ever you want to override

    <ui:define name="body">
          this will be the content that overrides your template "body", the rest will stay the same
    </ui:define>

</ui:composition>

不需要其他任何东西的原因是因为 <ui:compsition 标签不会考虑其标签之外的任何内容。
