Integrating Jetty with RESTEasy
提问by rmoh21
Any links on how to integrate Jetty and RESTEasy? I am kinda stuck trying to configure RESTEasy with Jetty together....and there seems to be no credible help on the web.
关于如何集成 Jetty 和 RESTEasy 的任何链接？我在尝试将 RESTEasy 与 Jetty 一起配置时遇到了困难......而且网络上似乎没有可靠的帮助。
public static void main(String[] args) throws Exception
{
Server server = new Server(8080);
WebAppContext context = new WebAppContext();
context.setDescriptor("../WEB-INF/web.xml");
context.setResourceBase("../src/webapp");
context.setContextPath("/");
context.setParentLoaderPriority(true);
server.setHandler(context);
server.start();
server.join();
}
My Web.xml is copied directly from: http://docs.jboss.org/resteasy/docs/1.0.0.GA/userguide/html/Installation_Configuration.html
我的 Web.xml 是直接从以下位置复制的：http: //docs.jboss.org/resteasy/docs/1.0.0.GA/userguide/html/Installation_Configuration.html
The error I get back is a HTTP 404 when I try to open up a link in my resource file. Everything looks reasonable on the surface, any suggestions?
当我尝试打开资源文件中的链接时，返回的错误是 HTTP 404。表面上看起来一切都很合理，有什么建议吗？
My resource file looks like:
我的资源文件看起来像：
package webapp;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
@Path("/*")
public class Resource {
@GET
public String hello() {
return "hello";
}
@GET
@Path("/books")
public String getBooks() {
return "books";
}
@GET
@Path("/book/{isbn}")
public String getBook(@PathParam("isbn") String id) {
return "11123";
}
}
This is the prints that I see when Jetty starts up:
这是我在 Jetty 启动时看到的打印：

To get RESTEasy and Jetty to work together withouta web.xml ensure you have a dependency on resteasy-servlet-initializer in your pom.xml.
要让 RESTEasy 和 Jetty 在没有web.xml 的情况下协同工作，请确保您在 pom.xml 中依赖于 resteasy-servlet-initializer。
This may help (JBoss RESTEasy documentation): https://docs.jboss.org/resteasy/docs/3.0.4.Final/userguide/html/Installation_Configuration.html#d4e111
这可能会有所帮助（JBoss RESTEasy 文档）：https: //docs.jboss.org/resteasy/docs/3.0.4.Final/userguide/html/Installation_Configuration.html#d4e111

Are you sure that @Path("/*") is correct path. Try @Path("/") maybe this * is a problem. As far as I know path expressions does not accept regexps.
您确定 @Path("/*") 是正确的路径吗？试试 @Path("/") 也许这 * 是一个问题。据我所知，路径表达式不接受正则表达式。
EDIT
编辑
I was wrong, you can use regexps in @Path, at least RESTEasy supports that.
我错了，你可以在@Path 中使用正则表达式，至少RESTEasy 支持。
