如何创建 Spring 3 + Tiles 2 Web 应用程序使用 REST-ful URL?

发布于 2024-08-29 19:05:39 字数 1367 浏览 2 评论 0原文

我在使用 Spring 3.0 MVC 解析 URL 时遇到了很大的麻烦。我只是构建一个 HelloWorld 来尝试如何在 Spring 中构建 RESTful web 应用程序,理论上没什么复杂的。

我能够找到的所有示例都基于关注文件扩展名(“*.htm”或“*.do”)的配置,包括人工目录名称前缀(“/foo”)甚至前缀带有点的路径(丑陋),所有方法都使用一些人工正则表达式模式作为解析器的信号。对于 REST 方法,我希望避免所有这些麻烦,并仅使用应用程序的自然 URL 模式。我会假设(可能是错误的)在 web.xml 中我设置了“/*”的 url 模式并将所有内容传递给 DispatcherServlet 进行解析,然后仅依赖控制器中的 URL 模式。

我无法可靠地让我的解析器捕获 URL 模式,并且在我的所有试验中,这会导致资源未找到错误、堆栈溢出(循环)或某种不透明的 Spring 3 ServletException 堆栈跟踪 - 一个我对 Spring 一直感到不满的一个原因是,错误消息通常没有多大帮助。

我想使用 Tiles 2 解析器。我已将 *.jsp 文件放在 WEB-INF/views/ 中,并在应用程序根目录下有一个单行 index.jsp 文件,该文件重定向到由我的layout.xml(Tiles 2 配置器)设置的索引文件。

我做了所有正常的 Spring 3 高级配置:

<mvc:annotation-driven />

<mvc:view-controller path="/" view-name="index"/>

<context:component-scan base-package="com.acme.web.controller" />

...接下来是 UrlBasedViewResolver、InternalResourceViewResolver、UrlFilenameViewController 等的各种组合和配置,以及我的 Tiles 2 配置文件中的各种变体。然后在我的控制器中我尝试获取我的 URL 模式。问题是,我什至无法可靠地让解析器捕获发送到我的控制器的模式。

现在已经持续了好几天,而我认为实施起来非常简单的事情却没有取得真正的进展。我可能试图一次做太多事情,尽管我认为这应该是一个简单的(几乎是默认的)配置。我只是想创建一个简单的 HelloWorld 类型的应用程序,我不认为这是火箭科学。

不是我发布我自己的配置(遍布整个地图),有谁知道一个在线示例:显示一个使用 REST-ful URL 的简单 Spring 3 MVC + Tiles 2 Web 应用程序(即,避免强制 URL 模式)例如文件扩展名、添加的目录名或点)并仅依赖 Spring 3 代码/注释(即 Spring MVC 本身之外的任何内容)来完成此操作? 有没有简单的方法可以做到这一点?

非常感谢您的帮助。

I'm having a heck of a time resolving URLs with Spring 3.0 MVC. I'm just building a HelloWorld to try out how to build a RESTful webapp in Spring, nothing theoretically complicated.

All of the examples I've been able to find are based on configurations that pay attention to file extensions ("*.htm" or "*.do"), include an artificial directory name prefix ("/foo") or even prefix paths with a dot (ugly), all approaches that use some artificial regex pattern as a signal to the resolver. For a REST approach I want to avoid all that muck and use only the natural URL patterns of my application. I would assume (perhaps incorrectly) that in web.xml I'd set a url-pattern of "/*" and pass everything to the DispatcherServlet for resolution, then just rely on URL patterns in my controller.

I can't reliably get my resolver(s) to catch the URL patterns, and in all my trials this results in a resource not found error, a stack overflow (loop), or some kind of opaque Spring 3 ServletException stack trace — one of my ongoing frustrations with Spring generally is that the error messages are not often very helpful.

I want to work with a Tiles 2 resolver. I've located my *.jsp files in WEB-INF/views/ and have a single line index.jsp file at the application root redirecting to the index file set by my layout.xml (the Tiles 2 Configurer).

I do all the normal Spring 3 high-level configuration:

<mvc:annotation-driven />

<mvc:view-controller path="/" view-name="index"/>

<context:component-scan base-package="com.acme.web.controller" />

...followed by all sorts of combinations and configurations of UrlBasedViewResolver, InternalResourceViewResolver, UrlFilenameViewController, etc. with all manner of variantions in my Tiles 2 configuration file. Then in my controller I've trying to pick up my URL patterns. Problem is, I can't reliably even get the resolver(s) to catch the patterns to send to my controller.

This has now stretched to multiple days with no real progress on something I thought would be very simple to implement. I'm perhaps trying to do too much at once, though I would think this should be a simple (almost a default) configuration. I'm just trying to create a simple HelloWorld-type application, I wouldn't expect this is rocket science.

Rather than me post my own configurations (which have ranged all over the map), does anyone know of an online example that: shows a simple Spring 3 MVC + Tiles 2 web application that uses REST-ful URLs (i.e., avoiding forced URL patterns such as file extensions, added directory names or dots) and relies solely on Spring 3 code/annotations (i.e., nothing outside of Spring MVC itself) to accomplish this? Is there an easy way to do this?

Thanks very much for any help.

<bean id="tilesviewResolver" class="org.springframework.web.servlet.view.tiles2.TilesViewResolver" 
            p:order="0"/>

<bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
        <property name="definitions">
            <list>
                <value>/WEB-INF/tiles-defs/tilesConfig.xml</value>
            </list>
        </property>
</bean> 

请参阅 TilesViewResolver

<bean id="tilesviewResolver" class="org.springframework.web.servlet.view.tiles2.TilesViewResolver" 
            p:order="0"/>

<bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
        <property name="definitions">
            <list>
                <value>/WEB-INF/tiles-defs/tilesConfig.xml</value>
            </list>
        </property>
</bean>

您可以尝试 MVC-AJAX Spring 3 示例。

You may try the MVC-AJAX Spring 3 sample.

春季示例应用程序:petcare 具有以轻松方式定义的链接。
您可以从以下位置下载: https://src.springframework.org/svn/spring-samples/
步骤是:
1.定义tiles配置bean(配置xml文件)

<!-- Initializes the Apache Tiles CompositeView system -->
    <beans:bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
        <beans:property name="definitions">
            <beans:value>
                /WEB-INF/**/tiles.xml
            </beans:value>
        </beans:property>
        <beans:property name="checkRefresh" value="true" />
    </beans:bean>
  1. 定义嵌套在UrlBasedViewResolver中的tiles视图类解析器

    value="org.springframework.web.servlet.view.tiles2.TilesView" />

  2. 为每个布局/页面等定义tiles.xml定义文件。

The spring sample application : petcare has the linkages defined in a restful way.
You can download these from : https://src.springframework.org/svn/spring-samples/
The steps are:
1. Define the tiles configuration bean (configuration xml file)

<!-- Initializes the Apache Tiles CompositeView system -->
    <beans:bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
        <beans:property name="definitions">
            <beans:value>
                /WEB-INF/**/tiles.xml
            </beans:value>
        </beans:property>
        <beans:property name="checkRefresh" value="true" />
    </beans:bean>
  1. Define the tiles view class resolver nested in UrlBasedViewResolver

    value="org.springframework.web.servlet.view.tiles2.TilesView" />

  2. Define the tiles.xml definition files for each layout/page etc.
