转换Stripes应用程序以使用友好URL [英] Converting a Stripes application to use Friendly URLs

问题描述

我正在研究Fred Daoud的Stripes一书并尝试将Hello World应用程序转换为使用友好URL，因为我不是基于后缀的映射的忠实粉丝，如 http：// localhost：8080 / getting_started / Hello.action 。

I am working through Fred Daoud's Stripes book and trying to convert the Hello World application to use friendly URLs, as I'm not a big fan of suffix-based mappings like http://localhost:8080/getting_started/Hello.action.

这是以前的...

index.jsp：

index.jsp:

<jsp:forward page="/Hello.action"/>

web.xml：

<servlet-mapping>
    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>*.action</url-pattern>
</servlet-mapping>

我的HelloActionBean上没有UrlBinding。我让这本书的例子有效。

and I have no UrlBinding on my HelloActionBean. I have the book example working.

我想知道这些书的例子是否适合早期版本的Stripes，因为我已经下载了1.5.1和我的网页。 xml定义了StripesFilter和StripesDispatcher，而我见过在其他地方使用的DynamicMappingFilter，例如在Fred的TheServerSide上这篇文章中。

I'm wondering if the book examples may suit an earlier version of Stripes, as I've downloaded 1.5.1 and my web.xml defines the StripesFilter and StripesDispatcher whereas I've seen a DynamicMappingFilter used elsewhere, e.g. in this article by Fred on TheServerSide.

无论如何，我做了以下更改：

Anyway, I made the following changes:

index.jsp：

index.jsp:

<jsp:forward page="/hello"/>

web.xml：

<servlet-mapping>
    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>/*</url-pattern>
 </servlet-mapping>

HelloActionBean.java：

HelloActionBean.java:

**@UrlBinding("/hello")**
public class HelloActionBean implements ActionBean 
{

但是，当我尝试通过 http：// localhost：8080加载应用程序时/ getting_started 我看到了：

However, when I try to load the app through http://localhost:8080/getting_started I see this:

net.sourceforge.stripes.exception.ActionBeanNotFoundException: Could not locate an ActionBean that is bound to the URL [/]. Commons reasons for this include mis-matched URLs and forgetting to implement ActionBean in your class. Registered ActionBeans are: {/hello=class stripesbook.action.HelloActionBean, /controller/DefaultView.action=class net.sourceforge.stripes.controller.DefaultViewActionBean, /hello/=class stripesbook.action.HelloActionBean, /controller/DefaultView.action/=class net.sourceforge.stripes.controller.DefaultViewActionBean}
    at net.sourceforge.stripes.controller.AnnotatedClassActionResolver.getActionBean(AnnotatedClassActionResolver.java:341)

如果我通过 http：// localhost访问它： 8080 / getting_started / hello 服务器似乎进入循环，抛出一个接一个的异常。

and if I access it through http://localhost:8080/getting_started/hello the server seems to go into a loop throwing one exception after another.

任何建议表示赞赏 - 谢谢。

Any suggestions appreciated - thanks.

推荐答案

我一直在尝试其他一些事情让它运转起来......

I've been trying out a few other things and got it working ...

我删除了web.xml中现有的DispatcherServlet servlet和servlet-mapping定义，并替换为wit h DynamicMappingFilter。

I removed the existing DispatcherServlet servlet and servlet-mapping definitions in web.xml and replaced with the DynamicMappingFilter.

作为奖励，改变链接事件的传递方式，以便例如

As a bonus, to change the way link events are passed, so that e.g.

http://localhost:8080/getting_started/hello?randomDate=

变为

http://localhost:8080/getting_started/hello/randomDate

将ActionBean上的UrlBinding更改为：

change the UrlBinding on the ActionBean to:

@UrlBinding("/hello/{$event}")
