Question

晚安。我不明白为什么jsf组件无法转换为html页面。我正在尝试创建将转换为html表的dataTable。JSF版本为-2.1.6-SNAPSHOT

└───WebContent
│   Main.jsp
│   Page 0.xhtml
│   Page1.xhtml
│
├───META-INF
│       MANIFEST.MF
│
├───resources
│   └───css
│           CSS.css
│
└───WEB-INF
    │   faces-config.xml
    │   web.xml
    │
    └───lib
            javax.faces.jar
            jstl-1.2.jar

我正在尝试使用http://localhost:8080/Practice/Page1.xhtml获取Page1 在xhtml之前：

<h:body>
<div class = "Task">
    <h:dataTable value = "#{Countries.countries}" var = "country">
        <h:column>
            <f:facet name="header">Country</f:facet>
            #{country.name}
            //I have also tried outputText but the result is the same - empty
        </h:column>
        <h:column>
            <f:facet name = "header">Capital</f:facet>
            #{country.capital}
        </h:column>
    </h:dataTable>
</div>

这里将转换为HTML：

<div class="Task">
    <h:dataTable value="[Lesson2.Country@4d1e67be, Lesson2.Country@81ce079, Lesson2.Country@7f6b1dc8, Lesson2.Country@395e8b9d]" var="country">
        <h:column>
            <f:facet name="header">Country</f:facet>

        </h:column>
        <h:column>
            <f:facet name="header">Capital</f:facet>

        </h:column>
    </h:dataTable>
</div>

为什么没有转换jsf组件？

为什么在我试图显示国家/地区财产的地方没有空白？在浏览器和Eclipse中都没有什么不对的地方。

这是我的完整.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:ui="http://xmlns.jcp.org/jsf/facelets"
  xmlns:h="http://xmlns.jcp.org/jsf/html"
  xmlns:f="http://xmlns.jcp.org/jsf/core">


  <h:head>
  <title><ui:insert name="title">Default title</ui:insert></title>
  </h:head>

  <h:body>

    <h:dataTable id = "Id" value = "#{Countries.countries}" var = "country">
        <h:column>
            <f:facet name="header">Country</f:facet>
            <h:outputText value = "#{country.name}"/>
        </h:column>
        <h:column>
            <f:facet name = "header">Capital</f:facet>              
            <h:outputText value = "#{country.capital}"/>
        </h:column>

    </h:dataTable>

这里匹配

<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

<h：datatable>未转换为html代码
