Jersey RESTful Web服务gradle设置

Question

我坚持使用jersey库为RESTful Web服务创建gradle项目。项目配置应该能够在jetty应用程序服务器中启动服务。我已经找到了一个资源：https://github.com/ziroby/jetty-gradle-hello-world

我的解决方案的问题是，它使用了过时的球衣版本。我至少需要2版（最新的2.14版）。我试图在maven central上搜索新版本，但在版本2中，很多工件名称发生了变化，我无法正确配置它。

编辑：我在项目中并不特别需要Jetty服务器。它可以是任何应用程序服务器，适用于测试和调试我的应用程序。我也在生产中使用码头，所以使用码头会很不错。

apply plugin: 'java'
apply plugin: 'jetty'

repositories {
    mavenCentral()
}
dependencies {
    testCompile 'junit:junit:4.11'
    testCompile 'org.hamcrest:hamcrest-all:1.3'
    testCompile 'com.sun.jersey:jersey-client:1.17.1'

}
test {
    exclude '**/*IntegrationTest*'
}

task integrationTest(type: Test) {
    include '**/*IntegrationTest*'
    doFirst {
        jettyRun.httpPort = 8080    // Port for test
        jettyRun.daemon = true
        jettyRun.execute()
    }
    doLast {
        jettyStop.stopPort = 8091   // Port for stop signal
        jettyStop.stopKey = 'stopKey'
        jettyStop.execute()
    }
}

测试

public class HelloIntegrationTest {
    private static String HELLO_URL = "http://localhost:8080/hello";

    @Test
    public void testHello() throws Exception {
        Client client = Client.create();
        WebResource webResource = client.resource(HELLO_URL);
        String response = webResource.get(String.class);

        assertThat(response, is("Hello, World!"));
    }
}

资源

@Path("/hello")
public class HelloWebapp {
    private static HelloWorldService helloWorldService = new HelloWorldService();

    @GET()
    public String hello() {
        return helloWorldService.sayHello();
    }
}

第一

摆脱您目前拥有的所有泽西岛依赖关系

dependencies {
    testCompile 'junit:junit:4.11'
    testCompile 'org.hamcrest:hamcrest-all:1.3'
    +------------- ======= JUNK ======= ----------------+
    | testCompile 'com.sun.jersey:jersey-client:1.17.1' |
    | compile 'com.sun.jersey:jersey-core:1.17.1'       |
    | compile 'com.sun.jersey:jersey-server:1.17.1'     |
    | compile 'com.sun.jersey:jersey-servlet:1.17.1'    |
    +---------------------------------------------------+
}

以下是获得基本功能所需的唯一一个

dependencies {
    testCompile 'junit:junit:4.11'
    testCompile 'org.hamcrest:hamcrest-all:1.3'
   +-------------------- ========= GOLDEN ======== -------------------------+
   | compile 'org.glassfish.jersey.containers:jersey-container-servlet:2.14'|
   +------------------------------------------------------------------------+
   /* UPDATE */
   /* Starting Jersey version 2.26, you will also need the following */
   /* compile 'org.glassfish.jersey.inject:jersey-hk2:2.26' */
}

测试

import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.WebTarget;
import static org.hamcrest.CoreMatchers.is;
import static org.hamcrest.MatcherAssert.assertThat;
import org.junit.Test;

public class HelloIntegrationTest {

    private static String HELLO_URL = "http://localhost:8080/hello";

    @Test
    public void testHello() throws Exception {
        Client client = ClientBuilder.newClient();
        WebTarget webTarget = client.target(HELLO_URL);
        String response = webTarget.request().get(String.class);
        System.out.println(response);
        assertThat(response, is("Hello, World!"));
    }
}

这已经通过链接项目的克隆进行了测试。上面只显示了更改。

Update

对于JSON支持使用

org.glassfish.jersey.media:jersey-media-json-jackson:2.14

无需额外配置即可运行。
