将 Jetty 与 JAX-RS-Jersey 集成

2022-01-21 00:00:00 java jax-rs servlets jersey jetty

在对 web 和 Stackoverflow 进行了详尽的搜索之后，我仍然试图弄清楚如何将 Jersey 提供的 RESTlet 样式接口与 Jetty 集成.

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.

我已经启动并运行了我的 Jetty 服务器，因此 Jersey 似乎也很容易使用，有人知道如何将两者联系在一起吗?任何具体的链接都会有所帮助——我对 servlet 编程也有点陌生.

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

不久前我使用 Jetty 和 Jersey 创建了一个应用程序.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";
    }
}

码头启动器:

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);
        }
    }
}
