使用 ui:composition 时如何更改页面的头元素

我想问一个问题，我有一个像这样的主模板

<?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:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html">

    <h:head>
        <title>Login</title>
    </h:head>

    <h:body>
        <div id="top">
            <ui:insert name="top">
                <ui:include src="header.xhtml" id="header"/>
            </ui:insert>
        </div>
        <div>
            <div id="content">
                <ui:insert name="content"></ui:insert>
            </div>
        </div>
        <div id="bottom" style="position: absolute;top: 675px;width: 100%" align="center">
            <ui:insert name="bottom">
                <ui:include src="footer.xhtml" id="footer"/>
            </ui:insert>
        </div>
    </h:body>
</html>

在我的每个页面上我都使用类似的东西

<?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:ui="http://java.sun.com/jsf/facelets"
    xmlns:p="http://primefaces.prime.com.tr/ui"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html">

    <h:head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
        <title>City Setup</title>
    </h:head>

    <h:body>
        <ui:composition template="./WEB-INF/templates/layout.xhtml">
            <ui:define name="content">
                <h:form id="cityReviewform">
                    ......
                </h:form>

            </ui:define>
        </ui:composition>
    </h:body>
</html>

现在由于 ui;composition 发生了什么，我的图块属性现在在每个页面上工作，因为 ui:composition 丢弃它之外的每个标签。现在在每个页面上我都有一个登录标题（即主模板）。所以我想问我怎样才能在每个页面上显示自己的标题而不是登录（主模板标题）？

谢谢

I want to ask a question that i have a master template like this

<?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:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html">

    <h:head>
        <title>Login</title>
    </h:head>

    <h:body>
        <div id="top">
            <ui:insert name="top">
                <ui:include src="header.xhtml" id="header"/>
            </ui:insert>
        </div>
        <div>
            <div id="content">
                <ui:insert name="content"></ui:insert>
            </div>
        </div>
        <div id="bottom" style="position: absolute;top: 675px;width: 100%" align="center">
            <ui:insert name="bottom">
                <ui:include src="footer.xhtml" id="footer"/>
            </ui:insert>
        </div>
    </h:body>
</html>

On my each page i am using something like this

<?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:ui="http://java.sun.com/jsf/facelets"
    xmlns:p="http://primefaces.prime.com.tr/ui"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html">

    <h:head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
        <title>City Setup</title>
    </h:head>

    <h:body>
        <ui:composition template="./WEB-INF/templates/layout.xhtml">
            <ui:define name="content">
                <h:form id="cityReviewform">
                    ......
                </h:form>

            </ui:define>
        </ui:composition>
    </h:body>
</html>

Now what is happening that because of the ui;composition my tile attribute is now working on each page, because ui:composition discard every tag outside of it. Now on each page i have a title of Login(i.e of master template). So i want to ask that how can i do this that on each page, its own title shown instead of Login(master tempalte title)?

Thanks

在模板客户端中，之外的一切都会被忽略。您需要更改模板方法，为主模板中的标题提供，以便可以通过定义它。 code> 在模板客户端中。

主模板：

<!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html">

    <h:head>
        <title><ui:insert name="title">Login</ui:insert></title>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    </h:head>

    <h:body>
        <div id="top">
            <ui:insert name="top">
                <ui:include id="header" src="header.xhtml"/>
            </ui:insert>
        </div>
        <div>
            <div id="content">
                <ui:insert name="content" />
            </div>
        </div>
        <div id="bottom">
            <ui:insert name="bottom">
                <ui:include id="footer" src="footer.xhtml" />
            </ui:insert>
        </div>
    </h:body>
</html>

模板客户端：

<ui:composition template="/WEB-INF/templates/layout.xhtml"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:p="http://primefaces.prime.com.tr/ui"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html">

    <ui:define name="title">City Setup</ui:define>

    <ui:define name="content">
        <h:form id="cityReviewform">
            ...
        </h:form>
    </ui:define>
</ui:composition>

如何使用 JSF 2.0 Facelets 在 XHTML 中包含另一个 XHTML？

In the template client, everything outside <ui:composition> is ignored. You need to change your template approach to provide an <ui:insert> for the title in the master template, so that it can be defined by an <ui:define> in the template client.

Master template:

<!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html">

    <h:head>
        <title><ui:insert name="title">Login</ui:insert></title>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    </h:head>

    <h:body>
        <div id="top">
            <ui:insert name="top">
                <ui:include id="header" src="header.xhtml"/>
            </ui:insert>
        </div>
        <div>
            <div id="content">
                <ui:insert name="content" />
            </div>
        </div>
        <div id="bottom">
            <ui:insert name="bottom">
                <ui:include id="footer" src="footer.xhtml" />
            </ui:insert>
        </div>
    </h:body>
</html>

Template client:

<ui:composition template="/WEB-INF/templates/layout.xhtml"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:p="http://primefaces.prime.com.tr/ui"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html">

    <ui:define name="title">City Setup</ui:define>

    <ui:define name="content">
        <h:form id="cityReviewform">
            ...
        </h:form>
    </ui:define>
</ui:composition>
