通过manage-bean进行JSF动态模板选择

我的用例是为客户端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：

testTemplate1.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>

testTemplate2.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>

TemplateSelection.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。知道怎么解决吗？

实际上我复制了您的代码，只更改了名称，就成功了。你确定你的路径/名称是正确的吗？
