Question

我的问题是我实现了在新页面中重定向，“结果”在流程结束时。但是在导航器中，它仍然是重定向到此页面后它正在工作的页面的名称。因此，我无法在此页面“结果”上显示托管bean的属性。

这是我的“index.xhtml”：

<!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:f="http://java.sun.com/jsf/core"
    xmlns:p="http://primefaces.org/ui">
<h:head>
    <title>Test</title>
</h:head>

<h:body>

    <h:outputLabel value="Question :">
    </h:outputLabel>

    <h:form id="questionForm">

        <h:outputLabel
            value="#{questionBean.questions[questionBean.counter - 1].askedQuestion}">
        </h:outputLabel>

        <h:selectOneRadio valueChangeListener="#{questionBean.selectQuestion}">
            <f:selectItems
                value="#{questionBean.questions[questionBean.counter - 1].proposals}"
                var="proposal" itemValue="#{proposal}" />
            <p:ajax render="selectedQ" />
        </h:selectOneRadio>

        <h:commandLink value="Question suivante"
            action="#{questionBean.increment()}">
            <f:param name="pageId" value="1" />
        </h:commandLink>

    </h:form>

</h:body>
</html>

这是豆子：

        if (counter > 0) {
            user.getAnswers().add(selectedQuestion);
            System.out.println("answers " + user.getAnswers());
        }

        if (counter == questions.size()) {
            System.out.println("counter finished");

            for (int i = 0; i < user.getAnswers().size(); i++) {

            }

            System.out.println("resultCounter final : " + resultCounter);

            finalResult = resultCounter / (questions.size()) * 100;

            System.out.println("finalResult : " + finalResult);
            return "results";

        } else {

            counter += 1;
            System.out.println("counter out " + counter);
            return "index";
        }

    }

    public void selectQuestion(ValueChangeEvent event) throws AbortProcessingException {

        selectedQuestion = (String) event.getNewValue();

        String goodAnswer = questions.get(counter - 1).getGoodAnswer();

        if (selectedQuestion.equals(goodAnswer)) {
            System.out.println("good answer selected");

        }

    }

}

这是“results.xhtml”：

<!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:f="http://java.sun.com/jsf/core"
    xmlns:p="http://primefaces.org/ui">
<h:head>
    <title>Test</title>
</h:head>

<h:body>

    <h:outputLabel>Votre résultat est de </h:outputLabel>

    <h:outputText value="{questionBean.finalResult}"/> 

    <h:outputLabel>Entrez votre adresse mail pour les résultats</h:outputLabel>
    <h:inputText></h:inputText>


</h:body>
</html>

像我说的结果不能出现;所以结束页面不显示属性：

Votre résultat est de {questionBean.finalResult}Entrez votre adresse mail pour les résultats

如何使用JSF重定向到新页面，也在导航器链接中？
