java – 如何更新示例以使用最新版本Jetty(9.1.0.RC2)和Jersey(2

所以这里你Go – 两个例子,一个使用JettyHttpContainerFactory,另一个使用Jersey ServletContainer.

首先是泽西资源 – 非常简单.这将使用“test”路径设置类,使用hello路径设置一个方法,接受以纯文本形式生成“Hello World”的GET.

@Path("/test")
public class TestResource {

    @GET
    @Path("hello")
    @Produces(MediaType.TEXT_PLAIN)
    public String hello() {
       return "Hello World";
    }
}

接下来是服务器类：

public class ExampleServer {

    public static void main(String[] args) {

            URI baseUri = UriBuilder.fromUri("http://localhost/").port(9998).build();
            ResourceConfig config = new ResourceConfig(TestResource.class);
            Server server = JettyHttpContainerFactory.createServer(baseUri,config);
       }
}

最后是pom依赖项(注意这两个例子都有依赖关系).

<dependencies>
            <dependency>
                <groupId>org.eclipse.jetty</groupId>
                <artifactId>jetty-server</artifactId>
                <version>9.1.3.v20140225</version>
            </dependency>
            <dependency>
                <groupId>org.eclipse.jetty</groupId>
                <artifactId>jetty-servlet</artifactId>
                <version>9.1.3.v20140225</version>
            </dependency>
            <dependency>
                <groupId>org.glassfish.jersey.core</groupId>
                <artifactId>jersey-server</artifactId>
                <version>2.7</version>
            </dependency>
            <dependency>
                <groupId>org.glassfish.jersey.containers</groupId>
                <artifactId>jersey-container-servlet-core</artifactId>
                <version>2.7</version>
            </dependency>
            <dependency>
                <groupId>org.glassfish.jersey.containers</groupId>
                <artifactId>jersey-container-jetty-http</artifactId>
                <version>2.7</version>
            </dependency>
            <dependency>
                <groupId>org.glassfish.jersey.media</groupId> 
                <artifactId>jersey-media-moxy</artifactId> 
                <version>2.7</version> 
            </dependency>
            <!-- if you want to enable JSON support,include Moxy and Jersey will automatically enable the Feature -->

      </dependencies>

另请参阅https://jersey.java.net/apidocs/2.7/jersey/javax/ws/rs/core/Feature.html以了解功能 – 通过在类路径中包含Moxy,Jersey将自动注册MoxyJSONFeature.如果您更愿意使用Jackson,则需要手动注册JacksonFeature以及依赖项.您可以在注册资源的同一初始化参数中注册任何功能(以逗号分隔)

如果您希望配置为servlet,请将其用作ExampleServer代码

public class ExampleServer {

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

            Server server = new Server(9998);

            ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
            context.setContextPath("/");

            server.setHandler(context);

            ServletHolder jerseyServlet = context.addServlet(org.glassfish.jersey.servlet.ServletContainer.class,"/*");
            jerseyServlet.setInitOrder(0);

            /*This parameter tells the Jersey Servlet which of your REST resources to load. In this example we're adding the TestResource class. Jersey will then invoke this class for requests coming into paths denoted by the @Path parameter within the TestResource class. If you have multiple classes,you can either list them all comma separated,of use "jersey.config.server.provider.packages" and list the package name instead */
            jerseyServlet.setInitParameter("jersey.config.server.provider.classnames","foo.bar.TestResource");
            server.start();
            server.join();
       }
}

请注意servlet版本,我正在定义资源的类名.如果您有一些,最好使用jersey.config.server.provider.packages提供软件包名称

希望这可以帮助.如果您有任何问题,请告诉我.
