将Jetty与JAX-RS-Jersey集成 [英] Integrating Jetty with JAX-RS-Jersey

问题描述

在详尽搜索网络和Stackoverflow之后，我仍然在试图弄清楚如何整合Jersey和Jetty提供的RESTlet样式界面。

After an exhaustive search of the web and Stackoverflow, I am still stuck with trying to figure out how to integrate a RESTlet style interface provided by Jersey with Jetty.

我的Jetty服务器已启动并运行，因此Jersey似乎也很容易使用，有没有人知道如何将两者结合在一起？任何具体的链接都会有所帮助 - 我对servlet编程也有点新意。

I have my Jetty server up and running and as such Jersey seems pretty easy to use as well, does anyone know how to tie the two together? Any concrete links would help — I am a little new to servlet programming as well.

推荐答案

我使用Jetty和Jersey创建了一个应用程序一会儿回来。它只是一个标准的webapp：

I created an app using Jetty and Jersey a while back. It's just a standard webapp really:

web.xml：

<servlet>
    <servlet-name>rest.service</servlet-name>
    <servlet-class>
        com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
    <init-param>
        <param-name>com.sun.jersey.config.property.resourceConfigClass</param-name>
        <param-value>com.sun.jersey.api.core.PackagesResourceConfig</param-value>
    </init-param>
    <init-param>
        <param-name>com.sun.jersey.config.property.packages</param-name>
        <param-value>your.package.with.jersey.resources</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>rest.service</servlet-name>
    <url-pattern>/service/*</url-pattern>
</servlet-mapping>

休息资源：

package your.package.with.jersey.resources;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.SecurityContext;

@Path("login")
public class LoginResource {

    @Context
    private SecurityContext security;

    @GET
    @Produces(MediaType.APPLICATION_XML)
    public String login() {

        String email = security.getUserPrincipal().getName();
        return "ok";
    }
}

Jetty starter：

Jetty starter:

public class StartJetty {

    public static void main(String[] args) throws Exception {

        Server server = new Server();
        SocketConnector connector = new SocketConnector();
        // Set some timeout options to make debugging easier.
        connector.setMaxIdleTime(1000 * 60 * 60);
        connector.setSoLingerTime(-1);
        connector.setPort(8080);
        server.setConnectors(new Connector[] { connector });

        WebAppContext bb = new WebAppContext();
        bb.setServer(server);
        bb.setContextPath("/");
        bb.setWar("src/main/webapp");

        server.addHandler(bb);

        try {
            System.out.println(">>> STARTING EMBEDDED JETTY SERVER, PRESS ANY KEY TO STOP");
            server.start();
            while (System.in.available() == 0) {
                Thread.sleep(5000);
            }
            server.stop();
            server.join();
        } catch (Exception e) {
            e.printStackTrace();
            System.exit(100);
        }
    }
}
