我的用例是为客户提供动态选择模板的便利。我正在尝试使用托管 bean 选择模板，如下所示：

测试模板1.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:ui="http://java.sun.com/jsf/facelets"
      xmlns:h="http://java.sun.com/jsf/html">

    <h:head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
        <link href="./resources/css/default.css" rel="stylesheet" type="text/css" />
        <link href="./resources/css/cssLayout.css" rel="stylesheet" type="text/css" />
        <title>Facelets Template</title>
    </h:head>

    <h:body>
        Template 1

        <div id="content" class="center_content">
            <ui:insert name="content">Content</ui:insert>
        </div>

    </h:body>

</html>

测试模板2.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:ui="http://java.sun.com/jsf/facelets"
      xmlns:h="http://java.sun.com/jsf/html">

    <h:head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
        <link href="./resources/css/default.css" rel="stylesheet" type="text/css" />
        <link href="./resources/css/cssLayout.css" rel="stylesheet" type="text/css" />
        <title>Facelets Template</title>
    </h:head>

    <h:body>
        Template 2

        <div id="content" class="left_content">
            <ui:insert name="content">Content</ui:insert>
        </div>

    </h:body>

</html>

testTemplateClient.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:ui="http://java.sun.com/jsf/facelets">

    <body>

        <ui:composition template="#{templateSelection.selectedTemplate}">

            <ui:define name="content">
                Hello World
            </ui:define>

        </ui:composition>

    </body>
</html>

模板选择.java

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

import javax.inject.Named;
import javax.enterprise.context.Dependent;

/**
 *
 * @author aneeshaider
 */
@Named(value = "templateSelection")
@Dependent
public class TemplateSelection {

    /**
     * Creates a new instance of TemplateSelection
     */
    public TemplateSelection() {
    }

    private String selectedTemplate="./testTemplate1.xhtml";

    public String getSelectedTemplate() {
        return selectedTemplate;
    }

    public void setSelectedTemplate(String selectedTemplate) {
        this.selectedTemplate = selectedTemplate;
    }


}

我无法动态选择模板，而是根本没有选择模板，只显示客户端。任何想法，如何解决？

实际上，我复制了您的代码，仅更改了名称，并且有效。您确定您的路径/名称正确吗？
