这是我第一次处理网络服务。简单地说,我需要从泽西网络服务客户端(在javascript中实现的网页内)发送一个帖子请求到我的maven模块之一的泽西服务。
正如我所说,我已经在我的一个maven模块中创建了jersey-server,我想以某种方式运行它(我不知道如何运行Web服务程序。)在启动我的实现的客户端之前。通过在网上搜索,我看到了很多例子,但他们都使用了tomcat。所以我的第一个问题是,我是否需要使用tomcat(或类似的东西)才能运行Web服务?其次,下面我分享了我的泽西服务器模块。我怎么能开始运行呢?
package com.exampleProject.rest;
import javax.ws.rs.*;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import java.util.List;
@Path("/test")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class SiderRecommender {
@POST
@Path("/functiontest")
public List<Recommendation> sampleFunction() {
// return something here. I removed it for simplicity.
}
}

您没有 在已安装的网络服务器中运行Jersey应用。您可以在嵌入式服务器中运行它,这意味着服务器以独立模式运行,使用正常的main
方法。
如果您正在使用Maven,并且熟悉创建Maven原型,则可以使用jersey-quickstart-grizzly2
原型
jersey-quickstart-grizzly2
除外)jersey-quickstart-grizzly2
)。这是您使用原型项目免费获得的所有内容。
Main.java
package com.underdog.jersey.grizzly;
import org.glassfish.grizzly.http.server.HttpServer;
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
import org.glassfish.jersey.server.ResourceConfig;
import java.io.IOException;
import java.net.URI;
/**
* Main class.
*
*/
public class Main {
// Base URI the Grizzly HTTP server will listen on
public static final String BASE_URI = "http://localhost:8080/myapp/";
/**
* Starts Grizzly HTTP server exposing JAX-RS resources defined in this application.
* @return Grizzly HTTP server.
*/
public static HttpServer startServer() {
// create a resource config that scans for JAX-RS resources and providers
// in com.underdog.jersey.grizzly package
final ResourceConfig rc = new ResourceConfig().packages("com.underdog.jersey.grizzly");
// create and start a new instance of grizzly http server
// exposing the Jersey application at BASE_URI
return GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI), rc);
}
/**
* Main method.
* @param args
* @throws IOException
*/
public static void main(String[] args) throws IOException {
final HttpServer server = startServer();
System.out.println(String.format("Jersey app started with WADL available at "
+ "%sapplication.wadl\nHit enter to stop it...", BASE_URI));
System.in.read();
server.stop();
}
}
MyResource.java
package com.underdog.jersey.grizzly;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
/**
* Root resource (exposed at "myresource" path)
*/
@Path("myresource")
public class MyResource {
/**
* Method handling HTTP GET requests. The returned object will be sent
* to the client as "text/plain" media type.
*
* @return String that will be returned as a text/plain response.
*/
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getIt() {
return "Got it!";
}
}
MyResourceTest.java
package com.underdog.jersey.grizzly;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.WebTarget;
import org.glassfish.grizzly.http.server.HttpServer;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import static org.junit.Assert.assertEquals;
public class MyResourceTest {
private HttpServer server;
private WebTarget target;
@Before
public void setUp() throws Exception {
// start the server
server = Main.startServer();
// create the client
Client c = ClientBuilder.newClient();
// uncomment the following line if you want to enable
// support for JSON in the client (you also have to uncomment
// dependency on jersey-media-json module in pom.xml and Main.startServer())
// --
// c.configuration().enable(new org.glassfish.jersey.media.json.JsonJaxbFeature());
target = c.target(Main.BASE_URI);
}
@After
public void tearDown() throws Exception {
server.stop();
}
/**
* Test to see that the message "Got it!" is sent in the response.
*/
@Test
public void testGetIt() {
String responseMsg = target.path("myresource").request().get(String.class);
assertEquals("Got it!", responseMsg);
}
}
pom.xml
- 我自己添加了jersey-media-json-jackson
和maven-assembly-plugin
,以便您可以创建一个可运行的jar文件。

综上所述,您可以从命令行cd
到项目并执行
mvn clean package
java -jar target/jersey-grizzly-jar-with-dependencies.jar
,应用程序将启动。
您可以从http://localhost:8080/myapp/myresource
那就是它。请注意,以上是一个普通的jar项目。因此,如果你不能按照如何创建原型,你可以将上面的所有内容复制到一个jar项目中。
另见:
答案 1 :(得分:-1)
答案 2 :(得分:-1)
我无法评论第一个答案。所以我在这里添加评论。如果选择使用原型生成项目,则命令行应为
mvn archetype:generate -DarchetypeArtifactId=jersey-quickstart-grizzly2 -DarchetypeGroupId=org.glassfish.jersey.archetypes -DinteractiveMode=false -DgroupId=com.underdog.jersey.grizzly -DartifactId=simple-service -Dpackage=com.underdog.jersey.grizzly -DarchetypeVersion=2.23.1
而不是link中的命令行。这将与peeskillet提供的pom一起使用
