h:outputLink将上下文路径添加到URL值的前缀 [英] h:outputLink prefixes context path to a URL value

问题描述

我有一个h:outputLink，如下所示:

<h:outputLink value="#{doc.value}" style="color:blue">#{doc.key}</h:outputLink>

该值为URL www.example.com.当我单击该值时，在地址栏中看到的URL是http://localhost:8080/Project/www.example.com.为什么上下文路径以URL为前缀?

The value is a URL www.example.com. When I click on the value, the URL I am seeing in the address bar is http://localhost:8080/Project/www.example.com. Why is the context path being prefixed to the URL?

我查找了生成的HTML，但是值是没有上下文路径的实际URL.我在JSF中尝试了<a>，但是没有区别.

I looked up the HTML generated, but the value is the actual URL without the context path. I tried <a> in the JSF, but there's no difference.

任何解决此问题的帮助将不胜感激.谢谢！

Any help to fix this would be appreciated. Thanks!

推荐答案

<h:outputLink /> 如果值字段是相对路径，则将其值附加到当前父路径(不是Servlet上下文).这意味着，如果您在http://localhost:8080/Project/users.xhtml中有此特定链接:

<h:outputLink /> appends its value to the current parent path (not the Servlet Context) if the value field is a relative path. It means that if you have this specific link in http://localhost:8080/Project/users.xhtml:

<h:outputLink value="sales.xhtml">
    Sales
</h:outputLink>

这将尝试将您重定向到http://localhost:8080/Project/sales.xhtml.

This will try to redirect you to http://localhost:8080/Project/sales.xhtml.

好吧，当您指定一个相对的地址时，JSF理解它必须将其附加到当前的父URL中.为了避免这种情况，请编写绝对网址:

Well, as you're specifying a relative one, JSF understands it must append it to your current parent url. In order to avoid that, write the absolute url:

public String getValue(){
    return "http://www.example.com";
}

<h:outputLink value="#{doc.value}">
    Custom external url
</h:outputLink>
