如何处理漂亮面孔“查询参数”在支持豆中？

我有一个用户列表（dataTable 上的 userId 上有一个指向 /user/view/{userId} 的链接）。单击此 userId 链接后，浏览器将按预期重定向到“查看”页面。

我有一个页面接受第一个用户的 url 模式 http://localhost:8080/user/view/1 和 http://localhost:8080/user/view/2< /code> 第二个等等，但我不知道在加载此页面后如何使用 userId 值。

如何使用 PrettyFaces URLRewriteFilter 实现此目的？当访问页面时 PrettyFaces 注入数据后，如何使用支持 bean 的值（1,2 等）加载数据。有人能解释一下吗？

<url-mapping id="view">
<pattern value="/user/view/#{bean.userId}/" />
<view-id value="/userview.jsf" />
</url-mapping>

我正在使用 JSF2+Primefaces.3.0.M3+Prettyfaces-jsf2.3.3.2 和 GAE。

原文

I have a list of users(dataTable with a link on userId that points to /user/view/{userId}). On clicking this userId link, the browser is redirected to the 'view' page as expected.

I have a page that accepts the url pattern http://localhost:8080/user/view/1 for first user and http://localhost:8080/user/view/2 for the second etc, but I don't know how to use the userId value once this page loads.

How can I achieve this with PrettyFaces URLRewriteFilter? How can I load data using the value of #{bean.userId} (1,2, etc) from the backing bean once PrettyFaces has injected it when the page is accessed. Can anybody explain?

<url-mapping id="view">
<pattern value="/user/view/#{bean.userId}/" />
<view-id value="/userview.jsf" />
</url-mapping>

您需要一个页面加载操作，由 URL 映射配置中的元素指定。首先，您的 bean 中需要一个方法，如下所示：

@Named("bean")
@RequestScoped
public class LoginBean {

public String loadLoggedUser() {
    if ( userId != null ) {
        this.user = user.findById(userId);
        return null;
    }
    return "failure";
}
}

其次，您需要将添加到 URL 映射：

<url-mapping id="view">
     <pattern value="/user/view/#{bean.userId}/" />
     <view-id value="/userview.jsf" />
     <action>#{bean.loadLoggedUser}</action>
</url-mapping>

这里我们定义了要执行的页面操作当请求与我们的模式匹配的 URL 时，在 bean 上，#{bean.loadLoggedUser}。例如：/user/view/2。

You need a page-load action, specified by the <action> element in your URL-mapping configuration. First, you will need a method in your bean, like this:

@Named("bean")
@RequestScoped
public class LoginBean {

public String loadLoggedUser() {
    if ( userId != null ) {
        this.user = user.findById(userId);
        return null;
    }
    return "failure";
}
}

Second, you will need to add the <action> to your URL-mapping:

<url-mapping id="view">
     <pattern value="/user/view/#{bean.userId}/" />
     <view-id value="/userview.jsf" />
     <action>#{bean.loadLoggedUser}</action>
</url-mapping>

Here we have defined a page-action to be executed on a bean, #{bean.loadLoggedUser}, when a URL matching our pattern is requested. For example: /user/view/2.

<url-mapping id="login">
        <pattern> /user/view/1 </pattern>
        <view-id> /legacy/user/login.jsp </view-id> <!-- Non JSF View Id -->
    </url-mapping>
