我遇到了一些我无法解决的问题。我正在做一个h:dataTable,有一些我可以访问的属性,有些属性我没有。不知道为什么......这是代码:
myPage.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://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<h:head></h:head>
<h:body>
<ui:composition template="/WEB-INF/templates/basic.xhtml">
<ui:define name="content">
<h:dataTable value="#{data.result}" var="table" width="30%" border="1">
<h:column>
<h:graphicImage value="#{table.image}" width="200" height="200" />
</h:column>
<h:column>
#{table.name}
</h:column>
<h:column>
#{table.description}
</h:column>
</h:dataTable>
</ui:define>
</ui:composition>
</h:body>
</html>
这是Data.java:
package com.sources;
import java.util.List;
public class Data {
private List<Article> result;
public Data() {
// name, description, image
result.add(new Article("Tales of", "game", "/Images/" + "image.jpg"));
result.add(new Article("Harry potter", "book1", "/Images/" + "image.jpg"));
result.add(new Article("Harry potter", "book2", "/Images/" + "image.jpg"));
}
public List<Article> getResult() {
return result;
}
}
"/Images/" + "image.jpg"
路径是正确的,如果我在"/Images/image.jpg"
h:graphicImage
中写value
,它就会正确显示。
完成后,Article.java:
package com.sources;
import java.util.List;
public class Article {
private String name;
private String description;
private String image;
public Article() {}
public Article(String name, String description, String image) {
this.setName(name);
this.setDescription(description);
this.setImage(image);
}
public String getName() {
return name;
}
public void setName(final String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(final String description) {
this.description = description;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
}
在myPage.xhtml中,我可以访问#{table.name}
,#{table.description}
,但不能访问#{table.image}
。
以下是我收到的错误:/myPage.xhtml @26,75 value="#{table.image}": Property 'image' not found on type com.sources.Article
