RESTEasy - 需要完整路径的@Path？ [英] RESTEasy - @Path requiring a full path?

问题描述

我正在搞乱JAX-RS并创建了一个调用生成JSON的REST服务的应用程序。我试过Jersey，一切都很顺利，但我不得不切换到RESTEasy，因为我的应用程序需要用JDK5构建。我将我的web.xml更改为以下内容：

I was messing around with JAX-RS and made an application which calls REST services which produce JSON. I tried Jersey and everything went fine, but I had to switch to RESTEasy as my application needs to be built with JDK5. I changed my web.xml to something like this:

<web-app>
<context-param>
    <param-name>resteasy.scan</param-name>
    <param-value>true</param-value>
</context-param>

<listener>
    <listener-class>
     org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap
    </listener-class>
</listener>

<servlet>
    <servlet-name>RESTEasy</servlet-name>
    <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>RESTEasy</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>
<!-- ... -->
</web-app>

所以我希望每个以/ rest开头的URL都由RESTEasy处理。我的服务如下：

So I expect every URL starting with /rest to be handled by RESTEasy. My services are as follows:

@Path("/services")
public class MyRESTServices {

    @GET
    @Path("service1")
    @Produces(MediaType.APPLICATION_JSON)
    public Object service1(Blah blah) {

    }
}

使用Jersey工作正常， http：// localhost / MyContext / rest / services / service1 绑定到我的service1（）方法。但是当我改为RESTEasy时，我有一个404：

This worked fine using Jersey, http://localhost/MyContext/rest/services/service1 was bound to my service1() method. When I change to RESTEasy, though, I had a 404:

HTTP状态404 - 无法找到相对的资源：/ rest / services / service1 of full path： http：// localhost / MyContext / rest / services / service1

这意味着RESTEasy处理了请求但找不到绑定到此URL的任何服务。

Which means that RESTEasy handled the request but could not find any service bound to this URL.

在我的课上，将 @Path（/ services）更改为 @Path（/ rest / services）工作了。你知道我为什么会有这种奇怪的行为吗？我读过的所有教程/文档都只提到相对路径，不包括/ rest前缀...

On my class, changing @Path("/services") to @Path("/rest/services") worked, though. Do you have any idea why I got this strange behaviour? All the tutorials/docs I read mentionned only relative paths, not including the /rest prefix...

推荐答案

解决方案：添加在您的web.xml中关注

Solution: add the following in your web.xml

<context-param>
    <param-name>resteasy.servlet.mapping.prefix</param-name>
    <param-value>/rest</param-value>
</context-param>

其中/ rest是< url-pattern> /的开头rest / *< / url-pattern>
