Question

我在JSF 2.0的视图中使用facelets。我有两个支持bean，两个xhtml视图文件和另一个xhtml模板文件。当我在webapp目录中有第二个视图并且我更改了语言时，一切都很好但是当我将mi第二个视图放入WEB-INF文件夹并且我更改语言时，我在chrome网络控制台中出现以下错误：

POST http://localhost:8080/Languages/WEB-INF/inventory.xhtml 404 (No Encontrado)

这些是我的支持豆：

LanguageBean.java：

package com.testapp;

import java.io.Serializable;
import java.util.LinkedHashMap;
import java.util.Locale;
import java.util.Map;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.context.FacesContext;

@ManagedBean(name = "language")
@SessionScoped
public class LanguageBean implements Serializable {

    private static final long serialVersionUID = 1L;

    private String localeCode;
    private static final String DEFAULT_LOCAL_CODE = "es";

    private static Map<String, Object> countries;
    static {
        countries = new LinkedHashMap<String, Object>();
        countries.put("English", Locale.ENGLISH); // label, value
        countries.put("Français", Locale.FRENCH);
        countries.put("Español", new Locale("es"));
    }

    public Map<String, Object> getCountriesInMap() {
        return countries;
    }

    public String getLocaleCode() {
        if(localeCode == null) {
            localeCode = DEFAULT_LOCAL_CODE;
        }
        return localeCode;
    }

    public void setLocaleCode(String localeCode) {
        this.localeCode = localeCode;
    }

    public void changeLanguage() {

        // loop a map to compare the locale code
        for (Map.Entry<String, Object> entry : countries.entrySet()) {

            if (entry.getValue().toString().equals(localeCode)) {

                FacesContext.getCurrentInstance().getViewRoot().setLocale((Locale) entry.getValue());

            }
        }

    }

}

InventoryBean.java：

package com.testapp;

import java.io.Serializable;
import java.util.Locale;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import javax.faces.context.FacesContext;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@ManagedBean(name = "inventory")
@ViewScoped
public class InventoryBean implements Serializable {

    private static final long serialVersionUID = 4576404491584185639L;

    Logger logger = LoggerFactory.getLogger(InventoryBean.class);

    // Failing path
private static final String INVENTORY_MAIN_VIEW = "/WEB-INF/inventory";
// Working path
    // private static final String INVENTORY_MAIN_VIEW = "/views/inventory";

    public String findProducts() {

        try {
            System.err.println("In inventory backing bean");
        } catch (Exception exception) {
        }

        return INVENTORY_MAIN_VIEW;

    }

    public void changeLanguage() {
        FacesContext.getCurrentInstance().getViewRoot().setLocale((Locale.ENGLISH));
    }

}

这些是视图文件：

default.xhtml

            <h:form id="contentForm">
                <h:outputText value="#{msg['internationalization.test']}" />
                <p:commandButton id="gettingProducts"
                    value="Getting the products..." action="#{inventory.findProducts}" />
            </h:form>
        </f:view>
    </ui:define>
</ui:composition>

inventory.xhtml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

            <h:form id="contentForm">

            </h:form>
        </f:view>
    </ui:define>
</ui:composition>

这是模板xhtml文件（header.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">

    xmlns:p="http://primefaces.org/ui"
    xmlns:ui="http://java.sun.com/jsf/facelets">
<f:view contentType="text/html">
    <h:head>
    </h:head>
    <h:body>
        <div id="content">
            <h:form id="headerForm">
                <h:panelGrid columns="2">
                    <p:outputLabel value="Language :" for="languages" />
                    <h:selectOneMenu required="true" id="languages"
                        value="#{language.localeCode}">
                        <f:selectItems value="#{language.countriesInMap}" />
                        <p:ajax event="change" update="@all"
                            listener="#{language.changeLanguage}" />
                    </h:selectOneMenu>
                </h:panelGrid>
            </h:form>
            <ui:insert name="contentBody" />
        </div>
    </h:body>
</f:view>
</html>

发生了什么事？

Answer 1

HTTP 404 error只是意味着＆＃34; Page Not Found＆＃34;。事实上，/WEB-INF文件夹中的文件无法公开访问。将意图在/WEB-INF文件夹之外公开访问的文件放入。

请注意，这与国际化完全无关。在国际化方面没有做任何事情时（例如简单导航），你会遇到完全相同的问题。
